Hydroxy-functional Copolymer with Acidic Groups Solution

Product Description

The product (HG-CohesivePro 4005) is a solution of hydroxy-functional copolymer with acidic groups, which is silicone-free and contains acid groups. The product is designed to be used as a adhesion promoter for aqueous and solvent-borne coatings to improve their adhesion to metallic substrates such as steel, galvanized steel, aluminum, non-ferrous metals and also to glass. Applicable coatings include industrial coatings, coil coatings (on galvanized steel) and protective coatings.

Features

HG-CohesivePro 4005 owns many notable features, including:

  • Has a strong affinity for metal substrates
  • Compatible with most binders
  • Has no adverse effect on the storage stability, recoatability and weather resistance of the coating
  • Stable even at high baking temperatures (briefly up to 280 °C) and does not cause yellowing
  • Can improve the flexibility of the coating without reducing the hardness
  • Can reduce the sedimentation of inorganic pigments and fillers
