Powder coatings produced with crosslinkers capable of curing at low temperatures and coated articles produced therefrom

摘要

A solid isocyanate-based composition having a glass transition temperature of at least 30 DEG C is produced by at least partially blocking the isocyanate groups of a polyisocyanate with a compound corresponding to the specified Formula I. This blocked isocyanate composition is useful in the production of powder coatings which are capable of being cured at temperatures of from 80 to 220 DEG C.
