WebPolyurethane paints cross-linked with the share of atmospheric oxygen. They are mainly urethane oils (obtained by reacting diisocyanates with natural unsaturated oils), and urethane-alkyd resins modified with unsaturated oils. Drying and cross-linking of these products takes place by oxidation (oxidative cross-linking). • WebPearlbond™ TPU (Thermoplastic Polyurethane) Pearlbond crystalline TPU is a cost-saving formulation for the production of Hot melt adhesives, and Reactive Hot Melts Adhesives (HMAs) and Reactive Hot Melts (HMPUR), typically used in automotive interior parts, bookbinding, furniture, textile and footwear. Pearlbond TPU for HMAs.
