Aldehyde Resin applied in coatings
Product Description
Polyaldehyde Resin
Charateristics:
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. ( Properties and uses are similar to Laropal A 81.)
