DESCRIPTION
MAX GRE A/B is a two-part epoxy-based resin system (Bis A/Bis F Epoxy Hybrid) formulated for gasoline resistance. It is a premium grade resin system for repairs and restoration of metal fuel tanks that demonstrates excellent adhesion to metals, aluminum and other substrates used in fuel cells and tanks.
MAX GRE A/B is 100% solids and does not contain non-reactive components. MAX GRE A/B is resistant to swelling, softening, and loss of adhesion from immersion and direct contact to modern gasoline and diesel fuels. It demonstrates excellent dimensional stability and resistance to impact damage.
MAX GRE A/B is used as a barrier coating for metal and FRP fuel cells. It provides a high degree of chemical-resistance against petroleum-based gasoline, diesel, and ethanol fuel blends (E85).
MAX GRE A/B is an anti-corrosion coating for steel substrates, and prevents oxidation on aluminum and copper metals.
MAX GRE A/B works well as an impregnating resin for fiberglass, carbon fiber fabrics for patching, reinforcing and fabricating FRP composite fuel cells. MAX GRE A/B is used as a strong adhesive for bonding metals, FRP composites, and most porous substrates.
Surface Preparation For Metal Tank Repair
The metal substrate must be cleaned appropriately to remove oily residue by chemical degreasing. Remove and loose or flaking rust, and for the best adhesion performance, abrade or sandblast the surface to bare metal, so the MAX GRE A/B coating is in direct contact with the metal substrate. Use acetone or alcohol to degrease the surface and ensure that the substrate is dry and free from contamination before application.
For aluminum substrates, chromic acid etching is recommended for bonding and coating.

Precaution: As with industrial chemicals of the same nature, avoid direct skin contact using protective gloves and eyewear. Ensure the work area is well ventilated when working with flammable fuels. Extinguish any flame source to prevent fuel vapors accidental ignition. Always practice safety first.
MAX GRE A/B is mixed 2:1 by weight or by volume and offers a 35 to 45 minute working time. Use a scale to measure the proper mix ratio accurately, which dramatically affects cured chemical resistance, especially when mixing small batch sizes. The mixed consistency is similar to cooking oil. MAX GRE is self-leveling and will continue to flow until the MAX GRE resin gels or converts to a solid.
As a coating, apply the MAX GRE using a brush or roller coat. The ideal coating thickness to create a hermetic barrier is 0.015-inch or 15 mils and may require several applications to achieve the target coating thickness. Allow the first coat to cure for 5 to 6 hours at 75°F and repeat the application directly on top of the previous application. Once the desired thickness is achieved, allow the MAX GRE to fully cure 36 to 48 hours at 25°C to 30°C before use.
To use the MAX GRE as an adhesive, prepare the substrates to its bare condition so the MAX GRE is directly applied and in full contact with the base substrate. Ensure bond foot-print is relative to the amount of force that is expected. Mix the proper amount of the resin and curing agent for the application. Bondline control media such as ‘Potter’s Glass Bead’ is typically mixed with the MAX GRE to meter the ideal bondline thickness of 5 to 7 mils. Apply the mixed MAX GRE on both substrates to be bonded and assemble. Apply sufficient clamping force to ensure both substrates are mated. Allow to fully cure for 36 to 48 hours at 25°C to 30°C before use.
MAX GRE also works well as a potting compound for encapsulating fuel level sensors. It is suitable up to a ¾-inch thick casting or embedding. Upon cure, MAX GRE is non-conductive and provides electrical insulation for low voltage signals for gauges and meters. MAX GRE bonds well to copper wires and holds connections in place. It is resistant to pull-outs from expansion and contraction coefficients and mechanical vibration from average use and environment.
As an impregnating resin for composite fabrication, use silane or volan treated fabrics for the best epoxy resin compatibility and wet-out. Saturate the fabric with the MAX GRE at 33 percent resin content. Allow to fully cure for 48 hours at 25°C to 30°C before use. Observe composite fabricating guidelines for making fuel cells.
Cured MAX GRE Specimens in E85 Gasoline Continuous Immersion Test
HARDNESS TEST AFTER 30 DAY IMMERSION
Testing the Durometer Hardness of the specimens determines if the cures resin is being affected by the gasoline immersion. The weights and Durometer Hardness of the specimens were measure before and after the immersion test and any changes in weights and hardness are measured.
After several years of continuous gasoline immersion, the MAX GRE test specimens exhibited excellent Shore hardness retention and weight stability demonstrating its excellent chemical resistance.
Testing Weight Change After Prolonged Gasoline Immersion.
Negligible Change In Weight (Less Than 0.03%) Measured, Demonstrating Excellent Gasoline (E85 Grade) Resistance.
Starting from June 2009 to February 2020, specimens have been fully immersed in gasoline and has shown no appreciable change in dimension, weight, and durometer hardness.

EVERYTHING YOU NEED TO MEASURE, MIX, DISPENSE & APPLY
Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system.
T
he 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.
