Curing Agents

QR Polymers provide curing agents for epoxy resins, mainly for applications at room temperature. These are as varied as ambient curing paints for metal or for concrete (industrial anticorrosion paints, marine anticorrosive primers, pipe coatings or tank linings), civil engineering applications such as self-levelling or trowellable floorings, mortars, concrete repair, concrete modification, tank laminating, or adhesives for tiles or concrete.

Our curing agents are of various types: unmodified and modified aliphatic or cycloaliphatic amines, epoxy/(cyclo)aliphatic amine adducts, poly(amino)amides and their adducts, Mannich bases and various special curing agents, including waterbornes.
