KHIMTRAST PU Enamel for polyurea, rubber crumb, self-levelling floors — UV-resistant

Sealers and topcoats

The enamel covers already finished coatings — KHIMTRAST ENP (universal) self-levelling floors, polyurea and rubber crumb — no earlier than 24 h after they have been installed. The aliphatic isocyanate-based hardener makes the coating weather- and UV-resistant, so the enamel is also used outdoors. Gloss is at least 70 %, adhesion to polymer substrates not more than 1 point, service range −50…+60 °C with short-term heating up to +140 °C.
