Application
1.Because of their excellent solubility and compatibility, KY-A81 can be used in m any types of ink formulations.
2.Depending on the application, KY-A81 improve gloss, hardness, body adhensive and resistance to yellowing.
3. Because of their good pigment wetting and very low solution viscosity, KY-A81, can be used for the manufacture with a high ink content.
4.KY-A81 is very stable to heat and can be used in baking finishes, neither causing odor now discoloration.
5.Because of its relatively low solvent retention, it only leads to slight increase of the drying time of physically drying finishes.(e.g.,cellulose and nitrate)
