Ingredients for hardeners such as TMA (trimellitic anhydride), BPA (bisphenol-A) or glycidyl esters are classified as hazardous. FreiLacke has therefore developed the "Freiotherm powder coating PS3005" (highly weather-resistant) and "Freiotherm powder coating PP3005" (polyester industrial grade) series. Both are polyester paint systems that do not require declaration. The paint systems are primarily suitable for industrial applications and for painting construction and agricultural machinery.
Primid is the trade name of a hardener that belongs to the chemical class of β-hydroxyalkylamides and shows its strengths above all in the crosslinking of powder coatings. In addition to very good corrosion protection, the material offers high weathering resistance and excellent color stability. With the use of the primide hardener and its toxicologically favorable profile, the new polyester system from FreiLacke does not require labeling: it is completely free of problematic components.
