Features:
Aldehyde resinis 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.

Application
●Because of their excellent solubility and compatibility, SM-81 can be used in many types of ink/coating formulations.
●Depending on the application, SM-81 improves the gloss, hardness, adhesion, and resistance to yellowing of coating.
●Because of their good pigment wetting and very low solution viscosity,SM-81 can be used for the manufacture of pigment pastes with high pigment content.
