RotoShield

ROTOSHIELD is a high performance polymer coating designed to yield multiple releases when used in the rotational molding process. This semi-permanent coating, when properly applied, will not build up on the tool surface and will not transfer or otherwise interfere with secondary bonding or painting. ROTOSHIELD is a 100% solvent-free, completely NON-VOC formulation that exceeds the most demanding environmental requirements and when combined with our water-based cleaner, WATERCLEAN, and optional water-based conditioner SEALBRITE, provides a 100% Non-Hazardous release system for the rotational molding industry.
