Additional Information

Chemical nature: 70% isocyanurate based
Applications: Adhesives
automotive OEM and car repair paints
fleet and maintenance coatings
Advantages: compatibility with 2K-PUR, polyesters, acrylates, flexible medium-oil or short-oil alkyd resins and other OH-group containing resins, dilution in aromatics and esters, light stability and outstanding weathering resistant in polyurethane paints, by partial use of Vestanat® T 1890 in 2K-PUR paints based on linear aliphatic polyisocyanates the drying performance, surface hardness, pot life and chemical resistance against enviromental impact can be improved
Storage: Vestanat® T 1890-E can be stored in unopened containers for at least one year without loss of quality
Handling: The basic reactivity of Vestanat® T 1890-E is lower compared to linear aliphatic polyisocyanates. In order to improve the reactivity, the use of tin- or bismuth-catalysts are recommended. The amount to be used depends on the type and the OH-number of the resin and is typically in the range of 0.01 and 0.1% by wt., calc. on solids.
