Luna-mer 2148 is a wax-free matting hardener, designed for use in durable exterior TGIC powder coatings. Luna-mer 2148 is capable of providing gloss ranges from 10-30% @ 60°. Due to its carboxyl group functionality, this hardener requires excess TGIC as a co-reactant in order to achieve controllable gloss stability at varying baking temperatures. Luna-mer 2148 also provides excellent performance characteristics including impacts and surface flow.
