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 epoxy compound is used over QTP 1700 primer to produce a thin-film paint and slip-resistant finish for rapid floor repairs. Work is permitted at substrate and air temperatures from +5 °C. At +20 °C, pedestrian traffic is allowed after 3 h and full mechanical load after 4 h. Shore D hardness is 87–93; pot life is 17 minutes.
