Huangshan Huahui Technology Matt Hardener HC55

Huangshan Huahui Technology Matt Hardener HC55 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.

    Application and Performance
    • HC55 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 systems as a hardener, making the coatings with super matte surface, excellent mechanical property and good reproducibility characteristic.
    • Due to HC55 has a higher melting point, iť'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).
    • 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.
    •  Dosage: E-12: HC68 mass ratio: (8-10):1.
