PRODUCT DESCRIPTION
MAX GRE THIXO A/B is a two-part epoxy-based resin system (Bis A/Bis F Hybrid) formulated for gasoline resistance. It is a premium-grade resin system for repairing and restoring fuel tanks. 
MAX GRE THIXO A/B to steel, aluminum, fiberglass-reinforced, and other substrates used in fuel cells and tanks. 
MAX GRE THIXO 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 with modern gasoline and diesel fuels. 
It demonstrates excellent dimensional stability and resistance to impact damage. 
MAX GRE THIXO A/B is used as a barrier coating for metal and FRP fuel cells.
It is also a strong adhesive for bonding and patching metals and FRP fuel tanks.
Upon cure, MAX GRE yields excellent resistance against petroleum-based gasoline, diesel with and without ethanol fuel blends (E85).

Induced Corrosion Caused By Ethanol Blend
Ethanol blended gasoline and diesel blends are more susceptible to water absorption due to the ethanol additive in almost all commercially sold fuel blends. Water molecule from ambient humidity is readily absorbed with ethanol ng ions forming an electrolyte solution. This creates high corrosion activity when the ethanol fuel blend comes in contact with metals.
MAX GRE A/B is electrically non-conductive, thus shielding the metal substrate making the metal less susceptible to corrosion. Fuel tanks made from steel(Fe) or aluminum(Al) tanks metal tanks are more susceptible to oxidation or corrosion.

Surface Preparation For Gas Tank Repair
The MAX GRE THIXO must be in direct contact with the base substrate to yield a strong bond.
The substrate must be well prepared to ensure good adhesion.Clean and degrease the oily residue left by gasoline or diesel.
Remove old coating by mechanical sanding or bead blasting.
Use acetone to degrease the surface before applying the MAX GRE resin system.The substrate must be dry and free of contaminants to ensure the repair yields a strong bond that does not peel or delaminate.

Test To Determine If The Surface Is Suitable For
MAX GRE Application.
Use this "water-bead" test to quickly check the wettability of the surface.

A surface that demonstrates low surface tension prevents
the liquid resin to wet-out and cause poor adhesion.

Mixing And Application
MAX GRE THIXO A/B is mixed 2:1 by weight or by volume and offers a 35 to 45 minute working time. Use a scale to accurately measure the proper mix ratio, which significantly affects cured chemical resistance, especially when mixing small batch sizes.
The mixed consistency is similar to ketchup and is easily applied using a brush or spatula.
The ideal coating thickness to create a hermetic barrier is 0.015-inch or 15 mils - the thickness of a business card.
MAX GRE THIXO will maintain this applied film thickness on a vertical plane.

For thicker applications, allow the first coat to cure for 5 to 6 hours at 75°F, then apply the second coat directly on top of the previous coat.
Once the desired thickness is achieved, allow the MAX GRE to fully cure for 36 to 48 hours at 25°C to 30°C before use.

To use the MAX GRE THIXO as an adhesive, prepare the substrates to its bare condition.
Remove any existing coating so the MAX GRE THIXO is applied directly to the base substrate and in full contact.
Ensure the bondline area is proportional to the expected force.

Mix the appropriate amounts of resin and curing agent for the application.
Bond line 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 assembled.
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.

Please view the following video demonstration of the proper mixing of epoxy resins. 
The resin and curing agent must be mixed to a uniform consistency to eliminate tacky or uncured spots.
