Tough-Coat

Durable UV Resistant Exterior Clear Coating

Tough-coat E90-78

KEY TOUGH-COAT E90-78 is a low viscosity, one component, UV resistant polymeric water-based urethane coating with excellent thermal shock resistance and outstanding mar, abrasion and chemical resistance. This one component (1K) pre-catalyzed, self-crosslinking coating does not require pre-mixing/activation with a second component, minimizing waste.

With a 30 minute tack-free time regardless of ambient conditions, this coating is ideal for applications requiring multiple coats per day and for high output production demands. TOUGH-COAT E90-78 is quick-drying and ready for light use within an hour and full service use within 24 hours. The resulting coating is a full strength, tough and durable coating that makes it ideal for sealing and substrate protection. The water-based formula allows for easy solvent-free water clean-up.
