Wetisol Spray 400 — hot-spray polyurea
Sprayed polyurea for foundations, tanks, roofs and bridges: a seamless membrane with 350–450% elongation, working from −60 to +90 °C.

Wetisol S-MP2 is a one-component zinc-filled polyurethane compound: it primes steel before Wetisol polycarbamide coatings and at the same time protects it from corrosion through a galvanising effect. The primer is used on tanks, metal fencing of water bodies, bridge supports, ship decks and hulls, drilling platforms and metal roofs. Work is possible at temperatures from −15 to +40 °C and air humidity of 30–98%, and the coat dries to degree 3 in no more than 2 h. Packaging — metal buckets of 1, 10 and 25 kg.
