Blocked Polyisocyanates

A blocked polyisocyanate for crosslinking of suitable hydroxylated resins like polyester, acrylic and alkyd resins. It may be classified as an exceptionally light fast and weathering resistant hardener; it is characterized by an excellent balance of reactivity and storage stability of the formulated paint. Application fields include exterior can coatings, coil coatings, automotive OEM topcoats and primers/surfacer.

A solvent-free, blocked cycloaliphatic polyisocyanate, based on isophorone diisocyanate used for crosslinking suitable hydroxylated resins like polyester, acrylic and alkyd resins. Dissolved in plasticizers, VESTANAT® B 1358/100 can also be used for modifying of PVC or other thermoplastic materials.

A blocked polyisocyanate for the crosslinking of OH-terminated resins/dispersions. Combined with suitable polyols, preferably resins with low transition temperature, coatings with excellent yellowing resistance and weather stability are achieved. VESTANAT® EP-DS 1205 can be used as sole crosslinker or in combination with melamine resins.
