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.
