Description
Matt Hardener TP55 is the salts of poly-carboxylic acid with cyclic amidine. It utilizes the two different reaction rates of group in molecular structure, and during the curing process, it generates non-uniform shrinkage then forms the matte surface. It has both gloss decreasing and curing functions.

Application
1. TP55 can be applied in epoxy powder system to generate the strong matte effect, terrific leveling performance and stable comprehensive properties. It can be used for pure epoxy and epoxy/polyester hybrid powder system as a hardener, making the coating with super matte surface, excellent mechanical property and good reproducibility characteristic.
2. TP68 can be widely used in epoxy resin or epoxy polyester mixed powder coatings, but can achieve a stable semi-gloss level in mixed powder coatings.
TP55 is suitable for semi-gloss level (60 ° )25 ~ 40% in both epoxy and hybrid powder coatings.
3. Due to TP55 has a higher melting point, it’s very important to evenly disperse it in formulation. The users can suitably increase the extruding temperature to make sure the good dispersion (don’t exceed 110°C).
