WANNATE HB-75B can be used as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties.
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. Variations between matt and dead-matt gloss can be obtained by suitable adjustment of the formulation. Epoxy polyester coatings with matt or dead-matt gloss may be achieved by replacing a portion of the polyester with an equivalent quantity of Luna®-mer B68-LC.
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.
Luna-MER B-68-C is a crosslinkable matting agent for epoxy and/or epoxy/polyester powder coatings, which provides consistent gloss
when cured at 180°C minimum. 60° gloss range between 0-25% can be achieved.
