Aliphatic polyisocyanate based on isophorone diisocyanate (IPDI) and dissolved aromatic 100 and n-butyl acetate. Used as an "additive resin" in existing, ready-for-use coating formulations to accelerate drying, curing, and chemical crosslinking to obtain shorter dry, tape, and recoat times, and improved hardness and gasoline resistance in cured films. Offers compatibility with air-drying alkyd resin.
