KY-A81-1 Aldehyde Resin
KY-A81-1 Aldehyde resin 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.

Remark
1、KY-A81-1 is a high viscosity product.
Application
● Because of their excellent solubility and compatibility, KY-A81-1 can be used in many types of ink/coating formulations.
● Depending on the application, KY-A81-1 improves the gloss, hardness, adhesion, and resistance to yellowing of coating.
● Because of their good pigment wetting and very low solution viscosity, KY-A81-1 can be used for the manufacture of pigment pastes with high pigment content.
● KY-A81-1 is very stable in heat and can be used for baking finishes, and it will not cause odor or discoloration.
● 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).
Storage and shipping
Shipped in a light-free condition and stored at a dry room temperature. Shelf life is usually 1 year. If the bags are not open, that are stored in a dry and well ventilated place, and if the property is tested OK, it can last up to 2 years.
