This solvent-free aliphatic polyaspartic ester resin carries secondary amino groups reactive with -NCO. It serves as a reactive diluent for 2K PU coatings with ultra-high solids and near-zero VOC, including floor coatings, anti-corrosion topcoats, automotive & commercial vehicle coatings and general industrial coatings, complying with indoor air quality standards. Its performance is similar to NH-1720, while industrial hygiene is improved thanks to drastically reduced diethyl fumarate content (< 0.5 wt.%).
Product Features
· Lower viscosity; usable as reactive diluent for polyaspartic coatings or raw material for high-solids low-viscosity eco-friendly coatings
· Moderate reactivity; blending with NH242 / NH243 extends pot life for hand-brushed polyurea
· Cured film features excellent resilience, gloss and smooth hand feel
· Reacts with TOCPOLY elastic curing agents to produce high-performance elastic materials with elongation up to 400%
