WEBAC® 4270E
WEBAC 4270E is a very low-viscosity, fast-curing EP primer that cures to a viscoelastic to rigid state, with constant volume and no tackiness. Thanks to its excellent wetting of the substrate and high compatibility with oil and moisture, the material penetrates well into dry, damp, open-pored, and even oily mineral substrates, where it promotes secure bonding. Due to its high mechanical strength, WEBAC 4270E is suitable as a special primer for demanding substrates as well as for mortar screeds, scratch coats, and leveling compounds.
