Standardtype for solvent and solvent-free systems. Reacts with Epoxy, Isocyanate and unsaturated compounds.Useable as a high reactive hardener for Epoxy-systems to enhancethe curing speed even at low temperatures. Additive for fast curing in high-solid PU-systems. Binder for Thiourethane-systems and Thiol-Ene- systems (thermal or UV-curing). Additive for radiation curing systems, to reduce the oxygen inhibition, volume shrinkage and to increase the hardening speed.Additive for polysulfide sealants to increase the crosslink density.
