WPA 3460

Polyurea Primer


WPA 3460 is a single component primer based on polyether polyol and modified MDI isocyanate. The primer is a polyurethane pre-polymer with a surplus of isocyanate which reacts with the moisture in the substrate to cure the product. The product was designed as a low viscosity concrete primer for preparing substrates prior to applying the WPA 3400 spray applied membrane.
