One-pack moisture curing polyurethane paint, pigmented with specific inert lamellar pigments. Thanks to the special lamellar structure of the pigmentation, a very tight paint film is obtained with excellent water and corrosion resistance. The inert pigmentation and the polyurethane binder provide a high chemical resistance.
These properties make it possible to apply Polyguard as coal tar free alternative where normally coal tar products are used.
Polyguard is especially recommended for immersion circumstances (seawater).
