Abstract
Coating compositions, comprising (I) blocked urethane prepolymers, particularly those derived from tetramethyl-xylylene diisocyanate, and (II) curatives, such as polyether polyamines, oxyalkylene ethers of polyamines and ketimines of polyamine, are disclosed. Plastisol compositions, which comprise vinyl chloride polymers, plasticizers, and adhesion promoters, comprising (I) a blocked polyisocyanate, such blocked urethane prepolymers as above, or isocyanurate or biuret-containing blocked polyisocyanate, and (II) active amino group-containing mono- or poly-amide compounds, are also disclosed. These compositions are useful for coating metal surface to improve resistance to chipping.
