QTP® 4630 — rigid-elastic coating for ramps and entrances
Epoxy-polyurethane coating for areas of heavy vehicle traffic, ramps and entrances, performing from −60 to +60 °C.

This multi-purpose epoxy primer is distinguished by its pigmented component A, a thick coloured liquid. It is used in epoxy and polyurethane systems, for tight-scrape filling neat or with quartz, and as a binder for repair compounds and hygienic coving. Pot life is 35 minutes and compressive strength 78 MPa. The kit weighs 24 kg; the shelf life is 12 months.
