Isothane Elastomer A755 is a polyether based resin system which, when combined with Isothane M15 Prepolymer, will produce a polyurethane elastomer of 55-60°A hardness. Elastomer A755 is cold castable, free from MOCA, mercury based catalysts, TDI and flammable solvents.
Two Component elastomer PPG based resin/ MDI prepolymer.

Uses
Typical uses include the production of medium sized castings and medium dimension mould production. The products excellent resistance to hydrolysis lends itself to marine and other wet environment uses.
Elastomer A755 can be readily processed and cured at room or elevated temperatures. The convenient mix ratio and low viscosity allow easy processing.
