Formlastic™ Series

Low Shrinkage Urethane Rubber

Formlastic 48 & 60 are filled urethane rubbers used to make molds for production casting of concrete. They feature low viscosity for easy mixing / pouring and cure with minimal bubble entrapment. Mix ratio is 1A:1B by volume, and the rubbers cure in 24 hours to an ultimate Shore hardness of either Shore 48A or 60A. Cured rubber is dimensionally stable (low shrinkage), offers good wear resistance and will render color accurate concrete castings.

IMPORTANT: This product does not contain mercury or quartz silica (non-carcinogenic).
