Description
MAX BOND LOW VISCOSITY A/B is a two-part epoxy/polyamide resin system specially formulated to provide structural strength to a variety of marine and boat building uses such as structural fiberglassing, waterproofing, and high strength bonding application.
It is the low viscosity version (thinner) of MAX BOND family of marine grade resin systems providing improved ease of use and faster fiberglass fabric wetting.
Please note that the consistency of this formulation is similar 30-weight motor oil. It is only diluted from the base epoxy and curing agent formulation to yield ease of use and general fabric impregnation. Over dilution of the resin system
(below 1000 cPs similar to the consistency of mineral oil) are over diluted with lower functional epoxy diluents that will also dilute or lower the final cured mechanical strength. All the MAX BOND series of epoxy resin demonstrates excellent adhesion to polyester based marine hulls.
It is best suited for structural building and reinforcement, waterproofing and in all manners of boat building construction, repair, and maintenance.
MAX BOND LOW VISCOSITY A/B demonstrates negligible loss of mechanical properties from continuous water immersion. MAX BOND LOW VISCOSITY A/B will cure even in humid and low-temperature conditions. It is generally room temperature cured but can be snap cured at elevated temperatures for a short period of time.
MAX BOND LOW VISCOSITY A/B demonstrates structural bond strengths to a variety of substrates commonly used in the manufacturing of modern marine vessels of such as wood, steel, aluminum, copper and other metal alloys, polyester constructed fiberglass and most plastics.
MAX BOND LOW VISCOSITY A/B performs well in wide range of service temperature and resists cracking and delamination caused by repeated impact cyclic vibration, thermal expansion/contraction and physical breakdown due to continuous seawater immersion.

Apply another coat of the epoxy, this time do not add any solvent to insure maximum strength development.
- Use a plastic spreader or flat plastic spreader to consolidate the fiberglass to wood. Use this to smoothen the fiberglass and remove excess resin and entrapped air bubbles.
- Allow the epoxy resin to cure for 24 hours.
- Upon cure, the cured laminate can be directly painted with a UV resistant polyurethane or acrylic paint to protect the epoxy resin from the damaging effects of direct UV (sunlight) exposure.

WHICH EPOXY IS BEST FOR YOUR APPLICATION?
Epoxy based polymers are one of the most versatile thermoset plastics that can be modified into a multitude of applications and fit very specific task as demanded by the application. It offers ease of use and generally safer to handle over other types of thermoset resins which make it the choice material for many high-performance composites.
New ideas demand new technology in material science and the skill to compose its constituent into a synergistic composite.
What is impact testing?
Impact testing is one of the most revealing test methods that demonstrate a material's ability to resist and withstand a high-rate of pressure loading at a short amount of time. Its behavior during and after the impact can define its maximum mechanical property and conditional limits upon its destruction.
The impact resistance of an object provides the ultimate measure of its resistance to its definitive destruction. Governed by the many laws and dynamics of physics, a skilled chemist or materials engineer can determine the design equilibrium and ultimate performance by careful analysis of the material’s disassociation and the manner of its destruction.
With this knowledge, other aspects of mechanical performance can be accurately derived and through skillful engineering, one can determine the impact energies the part can withstand and design the construction that will resist such assaults over the projected life span.

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. |

The fabric is more pliable and can comply with complex contours and spherical shapes. Because of its tight weave style,
satin weaves are typically used as the surface ply for heavier and courser weaves.
This technique helps reduce fabric print through and requires less gel coat to create a smoother surface.
Step Three:
Proper Lay-Up Technique
Pre-lay-up notes
Lay out the fabric and pre-cut to size and set aside
Avoid distorting the weave pattern as much as possible
For fiberglass molding, ensure the mold is clean and adequate mold release is used
View our video presentation above "MAX EPOXY RESIN MIXING TECHNIQUE"
Mix the resin only when all needed materials and implements needed are ready and within reach
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 weights regardless of weave pattern
1 yard of 8 OSY fabric at 38 inches wide weighs 224 grams
1 yard of 10 OSY fabric at 38 inches wide weighs 280 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 224 GRAMS
(224 grams of dry fiberglass / 60%) X 40% = 149.33 grams of resin needed
So for every square yard of 8-ounce fabric,
It will need 149.33 grams of mixed resin.
Computing for resin and curing agent requirements based on
149.33 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
149.33x 66.67%= 99.56 grams of Part A RESIN
149.33x 33.33%= 49.77 grams of Part B Curing Agent
99.56+ 49.77 = 149.33 A/B MIXTURE
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 film of 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 dispersed throughout the fiberglass with minimal mechanical agitation or by spreading.

For Vacuum Bagging And Resin Infussion Process
Similar to "addition cure" or catalytic polymerization, Ultraviolet Curing is another method that has gained popular use in the polymer adhesives and coatings application. It offers a unique curing mechanism that converts a liquid polymer into a solid plastic upon exposure to UV radiation. The two common commercially significant method are "FREE RADICAL INITIATION" and CATIONIC REACTION. In both reaction polymerization occurs via decomposition of a Photoinitiator blended within the resin system; upon exposure to the adequate wavelength of Ultraviolet energy the photoinitiator degrades and cause a ring opening or cleavage of the photoinitiator molecule and induces rapid polymerization or cross-linking.
The polymerization reaction can be either free radical or cationic and occurs almost instantaneous creation of a polymer network.
