The curing of a coating will not only depend on the chemistry, but also on the application in which it is utilised. In general, like 2K acrylic/isocyanate systems, the non-isocyanate acrylic must display good cure under ambient temperature and low bake (60-80°C) conditions. The minimum cure requirements, specific to the main end use sectors, have been summarised in table 6-2:
