QTP® 2640 (2640 F, 2640 G) — polyurethane-cement for heavy loads
Heat- and chemical-resistant polyurethane-cement for areas of extra-heavy mechanical and chemical exposure, continuously up to +130 °C.

This water-reducible epoxy compound forms a vapour-permeable coating with a semi-matt silky surface, making it suitable for substrates with residual moisture. It is poured or painted over QTP 3000 primer to produce smooth, slip-resistant, thin-film paint or highly filled levelling coatings. Pot life at 20 °C is 90 minutes, and continuous heat resistance is up to +65 °C. The solids content is 75 %.
