 CASTING.

4 FLUID OUNCES CAST VOLUME

MAX 1618 A/B is formulated without the use of any silicone based surfactants that cause turbidity even in very thick castings.

Silicone defoamers are formulation additives that cause mixed air bubbles to be unstable and causes self-degassing. It is commonly used in all types of industrial fluids to prevent foaming during processing.

It is an integral additive in paints protective and conformal coatings as an antifoam additive.

However, silicone defoamers and surfactants create turbidity in clear epoxy resin. It is purposely designed to be immiscible (will not blend with or form a stable solution) with epoxy resin polymers so when air bubbles formed from mixing of the curing agent to initiate polymer cross-linking, it causes air bubbles to be unstable. When an air bubble encounters the silicone defoamer compound within the mixture, the lamella or the skin boundary of the bubble loose structural equilibrium and causes it to burst due to the differential surface tension of the polymer resin and the suspended silicone molecules. These physical dynamics cause a defoaming action within the resin matrix.

This incompatibility between the epoxy polymer and the silicone defoamer cause turbidity and loss of optical transparency that is increasingly evident in thick castings or coatings.

MAX CLR-TC is our top coat resin system designed for thin film applications that is formulated with silicone based defoamers and surfactants to reduce the occurrence of air bubbles and surface blemishes from becoming stable as the epoxy polymer converts from a liquid to a solid plastic.

Heat Resistance Study By Shore Durometer Hardness Test

The heat resistance of MAX 1618 A/B was tested by heating a 2-inch cube in 5-degree increments and the Shore hardness was determined using both the Shore A and D scale. This test demonstrates the heat resistance of the MAX 1618 A/B by determining at what temperature the Shore Hardness reading dramatically change. At 140 °F a considerable change in Shore D Hardness Scale occurred due to the sharp needle-like indenter of the equipment began puncturing the surface of the specimen which may make the Scale D Hardness an unreliable test data.

The Shore A scale demonstrated a dramatic change in hardness at 240°F which demonstrates it maximum heat tolerance.


Shore Hardness is a measure of the resistance of a material to penetration of a spring loaded needle-like indenter.
Dr. Dmitri Kopeliovich 
Hardness of Polymers (rubbers, plastics) is usually measured by Shore scales.
Shore A scale is used for testing soft Elastomers (rubbers) and other soft polymers.
The hardness of hard elastomers and most other polymer materials 
(ThermoplasticsThermosets) is measured by the scale.Shore Hardness is tested with an instrument called Durometers. A Durometer utilizes an indenter loaded by a calibrated spring. The measured hardness is determined by the penetration depth of the indenter under the load.

Two different indenter shapes and two different spring loads are used for two Shore scales (A and D).

The loading forces of Shore A: 1.812 lb (822 g), Shore D: 10 lb (4536 g). 

Shore hardness value may vary in the range from 0 to 100. Maximum penetration for each scale is 0.097-0.1 inch.

This value corresponds to minimum Shore hardness: 0. Maximum hardness value 100 corresponds to zero penetration.

MAX 1618 A/B THICK COATINGS APPLICATION ON WOOD PLAQUES BAR TOPS AND COUNTER TOPS

The coverage will depend on 3 basic factors:

1. The thickness of the coating measuring from an impermeable substrate

The type of substrate or material

Will it absorb the liquid coating or not

The surface profile or roughness

The surface tension of the substrate

2. The method of application that will dictate the USAGE or LOSS FACTOR

Spraying the coating has the highest loss factor

Roll coating is less

Brush applied is even less

Flow coating yield the lowest material loss factor

3. Solids content; the MAX 1618 A/B is 100% solids meaning it does not contain any volatile solvents or nothing evaporates from the applied coating

COVERAGE CALCULATION GUIDE

USE THESE THEORETICAL FACTORS TO DETERMINE COVERAGE OF ANY UNFILLED EPOXY RESIN

TO DETERMINE COVERAGE ON A FLAT SMOOTH SURFACE, CALCULATE THE LENGTH X WIDTH X THICKNESS IN INCHES

TO OBTAIN THE CUBIC VOLUME INCH OF THE MIXED RESIN NEEDED.

USE THE FOLLOWING EQUATION:

1 GALLON OF RESIN CAN COVERS 1604 SQUARE FEET

PER 1 MIL OR 0.001 INCH CURED COATING THICKNESS

(LENGTH X WIDTH X COATING THICKNESS)/ 231 CUBIC INCHES PER GALLON = CUBIC INCHES OF COATING NEED

FOR EXAMPLE

50 INCHES X 36 INCHES X 0.010 (10 MILS) = 18 CUBIC INCHES

18/231= .0779 GALLON OF MIXED RESIN

USE THE FOLLOWING FACTORS TO DETERMINE THE GALLON NEEDED AND THE CONVERT IT TO THE APPROPRIATE VOLUME OR WEIGHT:

FOR EXAMPLE:

231 X .0779 = 17.99 CUBIC INCHES

OR

4195 GRAMS X .0779 = 326.79 GRAMS

FLUID GALLON 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 TO MASS CONVERSIONS

1 GALLON OF MIXED UNFILLED EPOXY RESIN = 9.23 POUNDS

1 GALLON OF MIXED UNFILLED EPOXY RESIN = 4195 GRAMS

BASICS STEPS OF WOOD SEALING AND WATERPROOFING

    • Insure that the wood is as dry as possible; any excessive moisture will be sealed within the wood once it is impregnated with the wood.
    • Use a fast evaporating solvent to dilute the epoxy such as acetone or MEK  (ketone based solvents). Add no more than 5% solvent by weigh or by volume to the mixed resin.
    • Insure that all wood surface is coated with the epoxy sealant. For best results coat the entire exposed surface area with the prepared epoxy resin mixture.
    • Apply multiple coats until all porosity of the wood is sealed; some grain raising can be expected upon coating.
    • Allow the applied coats to cure for at least 24 to 36 hours before proceeding
    • For a smoother finish, sand the cure surface just enough to remove surface gloss and removed and surface blemishes caused by the grain raising
    • Apply another coat of the epoxy, this time without the addition of the solvent to insure a hermetic seal and serve as an aesthetic top coat barrier.
    • Apply an aliphatic based polyurethane coating unto the epoxy coating if the wood structure is going to be exposed to direct UV
    • Allow to cure and then apply the reinforcing fiberglass if needed by applying the resin first and then apply the fiberglass unto the resin.

MAX 1618 A/B is supplied solvent free to save shipping, handling and packaging cost. A 3% to 5% addition of acetone as a  diluent or thinner will effectively lower the viscosity and surface tension of the resin and make an effective penetrating solution and create a hermetic barrier, making the wood impervious to water or ambient moistureAcetone 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.

 

http://www.aqmd.gov/rules/download.html

 

Using acetone as fast evaporating thinner provides higher cured properties since the bulk of the acetone evaporates prior to the MAX 1618 curing thus eliminating any plasticizing effect caused by the entrapped solvent within the resin matrix. Compared to other systems that utilize slow evaporating solvents MAX 1618 demonstrates higher wood penetrating and water proofing performance.

 

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. A 10% to 15% addition to

the mixed MAX 1618 resin provides excellent viscosity reduction and lowering of the epoxy resin's dynamic surface tension allowing deeper penetration while evaporating efficiently from the system.

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. 

MAX 1618 A/B is mixed at a 2:1 mix ratio and exhibits a very low initial viscosity. It is resistant from ‘blushing’, exhibits excellent resistance to air bubble entrapment and retention, moderate working time reactivity and it cures to a very transparent clear resin system with a low refractive index.

MAX 1618 A/B exhibits low dimensional shrinkage during cure, heat performance of up to 220°F, adhesion to 'hard to bond to' plastics and low surface energy (LSE) substrates with exceptional impact and chemical resistance. It's cured mechanical properties also demonstrate high compressive strength, toughness, tensile strength and other mechanical performance crucial in structural strength applications.

POSSIBLE HEAT CURING TECHNIQUES

If an oven is not available to provide the needed thermal post cure, exposing the assemble part to direct solar heat
(sun exposure) for a period will provide enough heat cure for the part to be handled.
 Other heat curing such as infrared heat lamps can be used if a heat chamber or oven is not available.

MAX EPOXY RESIN IN ONE CONVENIENT KIT
Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system.
The container in which the epoxy and curing agent is mixed is an important consideration when mixing an epoxy resin system. 
The container must withstand the tenacity of the chemical and must be free of contamination.
Most epoxy curing agent has a degree of corrosivity, as a general practice, protective gloves should be worn when handling chemicals of the same nature.
