TP55 Matt Hardener

 (Similar to Vestagon B55)

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 nonuniform 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 could be used in epoxy or epoxy-polyester hybrid powder coating widely but in hybrid  powder coating could be reach stable semi gloss level.

   TP55 no matter in epoxy resin or hybride powder coating is suitable for semi gloss level around60°2540%.

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℃).

4 .In hybrid matting powder system, the polyester resin with low acid value should be selected, and it can be determined by the tests in order to obtain perfect gloss and optimal comprehensive properties.
