WEBAC® 4270T
WEBAC 4270T is a low-viscosity, fast-curing epoxy primer. It is characterized by excellent adhesion to the substrate and high resistance to oil and moisture, and is also suitable for use at low temperatures. The material cures with constant volume and becomes tack-free, offering impressive mechanical strength. It is used as a special primer on demanding substrates and as a mortar for hollow coves.
