Roof Waterproofing Projects Spray Polyurea Waterproof Coating
Introduction
Spray Polyurea Waterproof Coating is a new type waterproof coating. A component is isocyanate compounds; B component is amine compounds with chain extender, pigment, and filler, and auxiliaries etc. Construction technology is applied by spraying to mix the two components, generating the elastic waterproof coating.
