Process of making fuel resistant material and product made therefrom

A fuel resistant material for use in collapsible tanks, comprising:

• a substrate having a primer coat impregnated thereon;
• a first rubber film layer of a first thickness applied on a first side of the substrate;
• a second rubber film of a second thickness applied on a second side of the substrate, the second rubber film being thinner than the first rubber film;
• and
• a third rubber film over laid on the second rubber film, the second rubber film having thickness approximately equal to a difference in thickness between the first rubber film and the second rubber film.

A fuel resistant material for use in collapsible tanks resulting from a process comprising:

• preparing a spreadable rubber mixture;
• spread coating the rubber mixture onto a substrate;
• drying the rubber and the substrate to create a primed substrate;
• applying a first rubber film on a first surface of the primed substrate and a second rubber film on a second surface of the primed substrate, the first rubber film being applied at a thickness greater than a thickness of the second rubber film on the second surface to create an off balanced substrate;
• applying a third rubber film to the second surface to a produce a thickness substantially equal to that of the first surface to create a final coated product;
• and
• curing the final coated product.
