Primid® products are crosslinkers of the chemical class of β-hydroxyalkyl- amide (HAA), which are used to cure powder coatings based on carboxylic polyester (PES) resins. The resulting coatings are – after cure – highly weather resistant and exhibit excellent color stability.
Further the high charge acceptance makes Primid® crosslinkers a preferred choice for tribo powder coatings.
Primid® crosslinkers are characterized by a favorable toxicological profile (no hazardous classification).

Primid® crosslinkers of the chemical class of β-hydroxyalkylamide (HAA), can be used to cure liquid polyester or acrylic resins containing free carboxyl functions.
Primid® products are soluble in water and hence also suited for water-born coating systems. The favorable toxicological profile (no hazardous classification) remains unchanged if the crosslinker is dissolved in water.
Primid® cured coatings are of specific interest for hygiene and food contact applications.
