Polytek Poly 74-40 15 Gallon Kit

Poly 75-60 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to an amber, Shore A60 rubber. This is a pourable rubber, but it can be easily thickened with PolyFiber II Thickener for brush-on application.

Poly 74-30 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to an amber (color varies), Shore A30 rubber. For a transparent, amber version of this rubber, consider Poly 74-30 Clear Liquid Rubber.

For Poly 74-Series, Poly 75-Series, Poly 77-Series & PT Flex Series polyurethane rubbers, add Part C Softener to  for a lower viscosity mix and softer cured rubber. Add Part X Accelerator to accelerate pour times and demold times.
