Product Description
KS-929 Single-component Polyurethane Waterproof Coating
KS-929 can be applied on wet surface and complicated projects with its unique mechanism of reaction by atmospheric moisture and
the NCO end group of the PUP to form a seamless, strong bonding, elastic and flexible waterproof film.
Product features
* One-component packaging, ready to use, avoid unstable condition when mixing
* Anti-aging, acid & alkali resistance, high & low temperature resistance performance
* Environment friendly: conform to the harmful substances standard GB 50325-2001
* Apply combine with high polymer membrane, self-adhesive polymer modified-bitumen waterproof membrane.
* High bonding strength, high adhesion, excellent performance
Applicable scope
Non-exposed roof, underground projects, kitchen & bath and non-drinking water project
Application procedures
