Quantum1 is specially engineered to have excellent filling properties, while eliminating the need for finishing putty. Dispensing and mixing is made easy with the 825mL cartridge. Never guess again how much catalyst is the right amount. Quantum1 utilizes patent pending 10:1 technology that is the successful integration of polyester and epoxy chemistries. As a result, Quantum1 has less shrinkage, better sandability and better repair quality than traditional body fillers and putties. Quantum1 also passes 500 hr salt spray (ASTM B117) and is compatible with HAPS-compliant and waterborne coatings.
