VCPU-3 Spraying Polyurea (Pure) Waterproof Coating
Introduction
VCPU-3 is a 100% solid, fast set, spray-applied, two component aromatic polyurea elastomer. The system consists of the A component, a quasi-prepolymer rich of free NCO, and the B component, a mixture of polyetheramine, amine extenders and other additives. The unique polyurea chemistry allows this material to be tolerant of moisture and lower temperatures during application. This means that high humidity and hidden moisture in concrete has minimal effect on the application of this product.
Features
* Fast cure, short downtime but non-sagging.
* Moisture and temperature insensitivity during processing.
* High thermal stability.
* Extraordinary physical properties.
* Excellent adhesion to primed concrete.
* Seamless, flexible and waterproof.
* High elongation properties, resistance to freeze-thaw.
* Superior weather resistance.
* No chalking and fading in long-term outdoor use.
