These epoxy curing agents provide enhanced handling and performance.
The company specially engineered Amicure IC-321 and Amicure IC-221 curatives, which are fresh amine curing agents. These curatives can be used together with HDI trimer isocyanates in order to produce aliphatic polyurea or polycarbamide coatings specifically designed for use in institutional and industrial flooring coatings.
Both curatives can be applied through roll, brush or airless spray device and are specially designed so as to provide an adequate working time. Zero VOC, excellent UV durability, low temperature cure, surface appearance and low color are the curatives’ performance features.
