Aldehyde Resin A81 for Coating/paint CAS 25054-06-2
Aldehyde resin A81 is a kind of condensation from urea and aliphatic aldehydes, bright and resistant to yellowing. It shows excellent compatibility with many coating/printing raw materials. It is soluble in most organic solvents and has very good wetting and dispersion in the formulation of paints. It is a kind of marvelous multifunctional coating additive used to improve the adhesion, gloss, hardness, solid content, and fullness. It can also be used in universal pigment pastes.

1. Because of their excellent solubility and compatibility, KY-A81 can be used in many types of ink/coating formulations.
2. Depending on the application, KY-A81 improves the gloss, hardness, adhesion, and resistance to yellowing of coating.
3. Because of their good pigment wetting and very low solution viscosity, KY-A81 can be used for the manufacture of pigment pastes with high pigment content.
4. KY-A81 is very stable in heat and can be used for baking finishes, and it will not cause odor or discoloration.
5. Because of its relatively low solvent retention, it only leads to a slight increase of the drying time of physically drying finishes (e.g. cellulose and nitrate).
