Crystal Colorless Granular Aldehyde Resin WIth Excellent Compatibility And Solubility
Polyaldehyde is a kind of hard resin with light colour, yellowing resistance and low viscosity.
It's non-toxic and soluble in most solvents used in coating. And it can be mixed and solved with many
basic resins used in coating. So it can raise coating's properties greatly, such as glossiness,buildines,
hardness of surface layer and flexibility. It has good wetting with pigments.
Polyaldehyde resin can be used in coating with high solid content.
