Luna-MER B68-LC is a salt of a polycarboxylic acid and is a cyclic amidine. Luna-MER B68-LC is a hardener to produce matt to dead matt pure epoxy and epoxy polyester powder coatings. Cured films based on this hardener offer excellent flow and mechanical properties.

Luna-MER 552 is a curing agent for TGICfree, exterior durable powder coatings based on carboxyl functional polyesters. Cured film performance is substantially comparable to those of Polyester/TGIC systems. Luna-MER 552 has an exceptionally clean toxicological profile resulting in powder coatings that are completely safe to work with.

HC68 series is a composed salt of cyclic-amidine and multi-acid. It utilizes the two different reaction rates of group in molecular structure, and during the curing process, it generates nonuniform shrinkage then forms the matt surface. It has both gloss decreasing and curing functions.

Luna-MER B55-LC is the salts of polycarboxylic acid cyclic amidine. The hardener, applied in suitable formulations can produce epoxy or hybrid coatings for matt or semimatt gloss with very good flow and properties. Variation between matt and semi-matt surface can be obtained by means of suitable adjustment of formulation.
