Properties and Applications
Blocked polyisocyanate for the combination with suitable hydroxylated resins, like polyester, acrylic and alkyd resins.
VESTANAT’B 1042 E enables the formulation of heat curing PUR coatings for curing temperatures of ≥ 110 °℃.
Due to the high reactivity of VESTANAT°B 1042 E an increased viscosity of the formulated paint can be noted during storage.
