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

A solid isocyanate-based composition having a glass transition temperature of at least 30° 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...
