摘要
The present invention relates to multi-component compositions including an isocyanate component and an amine component, wherein the isocyanate component includes a prepolymer, obtainable from toluene isocyanate and a polytetramethylene polyol, and the amine component includes a dialkylthio aryl diamine and possibly a polytetramethylene oxide polyamine. Corresponding compositions can be advantageously used as flowable or spreadable resin systems for producing surface protection coatings in casting house applications and are characterized by a significantly improved resistance to abrasion in comparison with conventional casting resin systems based on hexamethylene diisocyanate and dimethyl thiotoluene diamine.
