DESCRIPTION
MAX PCR A/B is a two-component epoxy based resin system formulated to provide excellent sealing properties for wood and porous substrates. It is specially designed as a protective coating and penetrating sealant against the marine environment, water, alkali and acidic compounds. MAX PCR A/B exhibits excellent resistance to various solvents, gasoline and prevents microbial and fungal infestation preserving the wood' structural properties.
MAX PCR A/B demonstrates durability and exceptional adhesion to wood, stone, masonry and concrete substrates.
MAX PCR A/B can also be utilized to stabilize and encapsulate rotted or damaged wood and prevent further deterioration. It will stabilize damaged wood by sealing the porosity to retard propagation of any fungal growth and reinforce wood rot by binding the wood fibers into a homogenized wood/resin composite. The cured coating will have a high gloss and “blush-free” finish that is receptive to a top coat finish formulation such as the MAX PCR A/B can withstand extremely cold temperatures and repeated thermal cycling without fracturing or peeling. It is resistant to deterioration due to fungal infestation, alkali damage from cementitious efflorescence and continuous water immersion.
MAX PCR A/B is supplied 100% solids (no solvent) and does not contain Ozone Depleting Chemicals.

Other Commercial Epoxy Penetrating systems contain highly toxic solvents such as toluene, naphtha and other aromatic solvents that are also considered as an environmental pollutant. Most epoxy penetrating solutions utilize and overuse slow evaporating solvents creating a weak resin barrier. These solvents do not take part in the polymerization process and if any unevaporated solvent cures within the resin matrix, it will lower the chemical resistance and mechanical properties of the penetrating resin.
Solvents entrapped within the cured epoxy matrix will continue to evaporate and cause dimensional shrinkage and cause the wood to drastically warp.
Adding the proper solvent will lower the dynamic surface tension of the resin thus improving the penetrating properties. It will also extend the working time providing longer penetrating periods.
MAX PCR A/B is supplied solvent free to save cost on packaging and shipping of an easy to incorporate Acetone solvent that will effectively lower the viscosity of the mixed resin and make an excellent wood penetrating sealer. Acetone is also considered as a None Hazardous Air Polluting Substance (None-HAPS) and is exempt under AQMD (Rule 102 Group 1, RULE 1107 and 1113) and EPA guidelines and mandates governing the release of petroleum-based solvents.
Using acetone as fast evaporating thinner, no more than 7% by weight or by volume, demonstrates the lowest loss of performance due to residual acetone within the cured resin matrix. Residual solvents entrapment will typically act as a plasticizer in the resin matrix causing lowered mechanical properties. Acetone is widely available at most paint or hardware store and can be added at the time of use. Other solvents can be used but acetone demonstrates the best results.
The recommended 7% addition to the mixed MAX PCR resin provides the highest viscosity reduction and lowering of the epoxy resin's dynamic surface tension allowing deeper penetration while evaporating efficiently from the system prior to the epoxy curing into a solid phase.
The fast evaporation and volatility of the acetone reduce any plasticizing effect upon cure of the resin matrix. Entrapment of any solvent within the cured epoxy matrix will eventually evaporate causing volume shrinkage, porosity, and loss of water-resistant properties.
Any entrapped solvent will act as a fugitive solvent that will lower the water and chemical resistance of the cured resin.

Mix the Resin And Curing Agent Only After The Surface Is Prepared For Application.
STEP 1. SURFACE PREPARATION
The quality of adhesion of any coating or adhesive application is dependent on how well the surface is prepared. The resin system must be able to properly 'wet-out' the surface to form a continuous film. Surfaces demonstrating poor wettability prevents the liquid resin from forming a cohesive bond. Improper surface wetting yields poor adhesion and will delaminate during use.
Wetting is the ability of a liquid to interfaces or wet-out a solid surface; its dynamics is expressed as surface tension. A surface that demonstrates low surface tension, such as waxed surface, oily surface or slick plastics like Teflon will prevent the liquid resin to wet-out and cause poor adhesion.
In the same respect, if the surface is coated from a previous application, the epoxy adhesion is limited to adhesion quality of the primary coating is applied over. Make sure to remove any loose or peeling old coating before application to avoid delamination. If possible remove the old coating by mechanical sanding or power washing so the applied epoxy is in direct contact with the base substrate. Applying a coating over oil-based stain should be avoided.POOR WETTING OF THE RESIN (CRAWLING) DUE TO OIL-BASED STAIN APPLIED ON WOOD
To achieve good surface wetting and crerate a strong bond, ensure the surface is oil-free. Degrease the surface and lightly sand to improve surface wetting.
The Following Surface Preparation Procedures Are Recommended.
METALS AND CONCRETE
Degrease Metals– Wipe surface with a lint-free rag dampened with Methyl Ethyl Ketone (MEK) or acetone to remove all oil, dirt, and grease.
Degrease Concrete- Use 2 cups of TSP (trisodium phosphate) detergent per 5 gallons of hot water and scrub with a stiff deck brush. Rinse with water and allow to dry.Etch Metals – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of:
Sodium Dichromate
4 Parts By Weight
Sulfuric Acid
10 Parts By Weight
Water
30 Parts By Weight
The solution is held at 160°F (71°C), and the parts left immersed for 5 to 7 minutes. Rinse – remove metal parts from etching bath and rinse with clean water. (distilled water is recommended).
Etch Concrete- Use commercially sold concrete etching solution (hydrochloric acid based works best). Neutralized per instructions, rinse and allow to dry thoroughly.
ALTERNATE PROCEDURE
Degrease, scour and dry – Often etching as outlined above is not practical. The metal surfaces may be cleaned by degreasing as noted above, scouring with an alkaline cleanser followed by rinsing and drying.Degrease and dry – Degrease the surface as noted above, sand or sandblast the surface lightly but thoroughly. Rinse with acetone or Methyl Ethyl Ketone (MEK), and dry.
GLASS
Degrease – With MEK as above, or with a strong boiling solution of a good grade household detergent.
Etch – For optimum results, degreasing can be followed by the chromic acid bath outlined above.
WOOD
Sand – Bonding surfaces should be sanded lightly, but thoroughly to remove all external contamination.
Clean – Carefully remove all dust, or particles of wood from sanded areas. A stiff and clean brush or compressed air can be used.
PLASTIC
Clean – Remove all dirt, oil, or other surfaces contaminated with detergent soap or degreasing solvent and water, followed by thorough rinsing and drying. A solvent that does not have a detrimental effect may also be used.
Sand – Surfaces to be bonded should be sanded lightly, but thoroughly to remove surface sheen.
Clean – Carefully remove all dust or particles of plastic from the sanded area. A clean brush, lint-free cloth, or compressed air may be used.
CHECK THE PART A OR RESIN BOTTLE FOR CRYSTALLIZATION
During the winter months, the PART A or RESIN component may crystallize and cause poor cure performance. Our MAX Epoxy Resins are formulated with high purity grade resin polymers which makes it prone to crystallization when exposed to temperatures below 57°F. Crystallization can also occur after the resin has been stored over a period. It will appear as a waxy white mass at the bottom of the bottle. The PART A or RESIN component must be in its liquid form to thoroughly mix with the PART B or curing agent to achieve full cure.
DO NOT USE UNLESS PROCESSED
View the following video for identification and processing.
DETERMINE THE AMOUNT THE BATCH SIZE NEEDEDBegin by mixing a small batch to gain experience with the polymerization process of the MAX PCR resin system. Blending amounts greater than 1000.0 grams or 1 quart in volume requires careful mixing and ensuring the mixed resin is applied and used within the established working time to prevent exothermic "run-away" reaction. Do not let the mixed resin to sit in mass greater than 10 minutes. The heat generated during polymerization will accelerate the chemical reaction and cause a 'run-away' reaction to occur that can generate temperatures above 300°F and cause an uncontrollable chemical reaction. Mix the proper amount of resin and curing agent and apply within 10-15 minutes to avoid this from occurring.Calculate the amount to be mixed by measuring the length x width x thickness of the area to be coated to obtain the cubic volume of the resin needed. Use These Factors To Convert Gallon Needed Into Volumetric Or Weight Measurements.
Fluid Gallon To Volume Conversion
1 Gallon = 231 Cubic Inches
1 Gallon = 128 Ounces
1 Gallon = 3.7854 Liters
1 Gallon = 4 Quarts
1 Gallon = 16 Cups
Fluid Gallon Mass Conversions
1 Gallon Of Mixed Unfilled Epoxy Resin = 9.23 Pounds
1 Gallon Of Mixed Unfilled Epoxy Resin = 4195 Grams
Take into account that some of the coating thickness will be absorbed into the porosity. Mix a batch of the MAX PCR at the proper 2:1 mix ratio and apply it onto the bare wood first, and allow to cure until it has set dry to the touch. This application will seal the surface and prevent further absorption and prevent air bubbles from outgassing that will cause unsightly bubbles from getting entrapped in the coating. The sealing application will also cause "grain-raining' to occur.
When a liquid coating is applied over wood, fibers will begin to swell as it gets impregnated with the resin.
This will produce what is called 'grain raising' to occur. Raised grains are small end fibers protruding from the coating causing unsightly unevenness. Allow the applied resin to cure and lightly sand the surface using fine-grit sandpaper. Once the surface is prepared, apply the second coat of MAX PCR which will yield a smooth blemish free coating.
CALCULATING HOW MUCH RESIN TO MIX
The coating thickness is a big factor that dictates resin coverage. For protective coatings, a minimum coating thickness of 0.010-inch or 10 mils is recommended. Thicker coating thickness up to 0.500 mils or 1/2 inch per can be applied; however, consider the exothermic heat the resin produces when cured in a concentrated mass. The larger the mass, the higher the exothermic temperature is generated, the shorter the working time
To calculate coating thickness of 0.010-inch or 10 mils is recommended.
Calculation: 1608 / 10 = 160.8 Square Feet 1 Gallon Coverage
For high-build or thick casting of 1/2 inch (500.0 mils)
Calculation: 1608 / 500 = 3.21 Square Feet 1 Gallon Coverage
MIXING PROCEDURE
The two components must be mixed thoroughly to eliminate problems such as tacky or uncured spots. Use the "two container method" as demonstrated in this video demonstration, which ensures a homogeneous mixture of the resin and curing agent.

APPLICATION DEMONSTRATIONS
Condition the ambient temperature to 75°F for best results. Ensure that the work area is dust free and well ventilated. MAX PCR is self-leveling and will continue to flow until it polymerization converts it to a solid phase. It can be applied by using a bristle or high-density foam brush/roller or poured into place. MAX PCR is self-leveling, ensure the surface is level and secure any leaks by using tape to create a temporary patch and prevent leakage.

TYPES OF FABRIC WEAVE STYLE AND SURFACE FINISHING
FOR RESIN TYPE COMPATIBILITY
Fabrics are generally considered ”balanced” if the breaking strength is within 15% warp to fill and are best in bias applications on lightweight structures. “Unbalanced” fabrics are excellent when a greater load is required one direction and a lesser load in the perpendicular direction.
Weaves:
Most fabrics are stronger in the warp than the fill because higher tension is placed on the warp fiber keeping it straighter during the weaving process. Rare exceptions occur when a larger, therefore stronger thread is used in the fill direction than the warp direction.
PLAIN WEAVE Is a very simple weave pattern and the most common style. The warp and fill yarns are interlaced over and under each other in alternating fashion. Plain weave provides good stability, porosity and the least yarn slippage for a given yarn count. | 8 HARNESS SATIN WEAVE The eight-harness satin is similar to the four-harness satin except that one filling yarn floats over seven warp yarns and under one. This is a very pliable weave and is used for forming over curved surfaces. | 4 HARNESS SATIN WEAVE The four-harness satin weave is more pliable than the plain weave and is easier to conform to curved surfaces typical in reinforced plastics. In this weave pattern, there is a three by one interfacing where a filling yarn floats over three warp yarns and under one. | 2x2 TWILL WEAVE Twill weave is more pliable than the plain weave and has better drivability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two filling yarns. |

Pre-lay-up notes
Mix the proper amount of resin needed and be accurate proportioning the resin and curing agent. Adding more curing agent than the recommended mix ratio will not promote a faster cure. Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance. When mechanical load or pressure is applied to the composite laminate, the physical strength of the fabric should bear the stress and not the resin. If the laminate is over saturated with the resin it will most likely to fracture or shatter instead of rebounding and resist damage.
Don’t how much resin to use to go with the fiberglass?
A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight, this is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application.
For general hand lay-ups, calculate using 60% fabric weight to 40% resin weight as a safety factor. This will ensure that the fabricated laminate will be below 40% resin content depending on the waste factor accrued during fabrication.
Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY data.

Typical fabric weight regardless of the weave pattern
1 ounce per square yard is equal to 28.35 grams
1 square yard equals to 1296 square inches (36 inches x 36 inches)
FOR EXAMPLE
1 yard of 8-ounces per square yard (OSY) fabric weighs 226 grams
1 yard of 10-ounces per square yard (OSY) fabric weighs 283 grams
Ounces per square yard or OSY is also known as aerial weight, which is the most common unit of measurement for composite fabrics. To determine how much resin is needed to adequately impregnate the fiberglass, use the following equation:
(Total Weight of Fabric divided by 60%)X( 40%)= weight of mixed resin needed
OR
fw= fabric weight
rc= target resin content
rn=resin needed
MASTER EQUATION
(fw/60%)x(40%)=rn
FOR EXAMPLE
1 SQUARE YARD OF 8-OSY FIBERGLASS FABRIC WEIGHS 226 GRAMS
(226 grams of dry fiberglass / 60%) X 40% = 150.66 grams of resin needed
So for every square yard of 8-ounce fabric, it will need 150.66 grams of mixed resin.
Computing For Resin And Curing Agent Amount
150.66 grams of resin needed
MIX RATIO OF RESIN SYSTEM IS 2:1 OR
50 PHR (per hundred resin)
2 = 66.67% (2/3)
+
1 = 33.33%(1/3)
=
(2+1)=3 or (66.67%+33.33%)=100% or (2/3+1/3)= 3/3
150.66 x 66.67%= 100.45 grams of Part A RESIN
150.66 x 33.33%= 50.21 grams of Part B CURING AGENT
100.45 + 50.21 = 150.66 A/B MIXTURE
GENERAL LAY-UP PROCEDURE
Apply the mixed resin onto the surface and then lay the fabric and allow the resin to saturate through the fabric.
NOT THE OTHER WAY AROUND
This is one of the most common processing error that yields sub-standard laminates. By laying the fiberglass onto a layer of the prepared resin, fewer air bubbles are entrapped during the wetting-out stage. Air is pushed up and outwards instead of forcing the resin through the fabric which will entrap air bubbles. This technique will displace air pockets unhindered and uniformly disperse the impregnating resin throughout the fiberglass.
HAND LAY-UP TECHNIQUE
Eliminating air entrapment or void porosity in an epoxy/fiberglass lay-up process
Similar to the Vacuum Bagging Process where the negative pressure is used to apply consolidation force to the laminate while the resin cures, the resin is infused into the fabric lay-up by sucking the impregnating resin and thus forming the composite laminate.
The VARTM Process produces parts that require less secondary steps, such as trimming, polishing or grinding with excellent mechanical properties. However, vacuum infusion requires more additional or supplemental related equipment and expendable materials. So the pros and cons of each presented composite fabrication process should be carefully determined to suit the user's capabilities and needs.
Please view the following video demonstration which explains the process of Vacuum Infusion or VARTM process.
