Non-Benzene Aldehyde Resin A 81

KLT NonBenzene Aldehyde resin A 81 is condensed products from urea and aliphatic aldehydes, which improves gloss, hardness, body adhesion, and resistance to yellowing. Because of Aldehyde Resin A 81' excellent solubility and compatibility. Aldehyde Resin A 81 is recommended for applications such as grinding resin for universal pigment paste, Interior/exterior general industrial metal coating, Automotive OEM paint, Ink, wood coating, Powder coatings and so on.

Product description:

KLT Non-Benzene Aldehyde resin A-81 is a kind of aldehyde condensation resin, which is colorless or yellowish. It is soluble in almost paint solvents but not in water and compatible with almost coating raw materials, it is excellently yellowing-resistant.

It is usually as grinding resin in universal pigment dispersion and applied widely in coating formulation. It can effectively improve adhesion, hardness, gloss, solid content of paint and fullness of coatings. It is a kind of excellent multifunctional additive to coating/painting.
