Polyurethanes (PU)

Polyurethanes (PU) are widely used as resins in paints and coatings industry. Polyurethane paints and coatings exhibit excellent color retention, increased scratch, abrasion and moisture resistance as well as high gloss. Polyurethane can be used as one component system (1K formulation) and two components systems (2K formulations). In 1K formulation, a high molecular weight PU is mixed with isocyanate that cures with moisture; In 2K formulations, a polyisocyanate reacts with a polyol or a polyamine. Polyurethane coatings are applied on various substrates in diverse markets like automotive, aerospace, wood coating, floor coating, textile coating.
