Depending on the application, KYA-81 improve gloss, hardness,body adhension and resistance to yellowing while KY-120 improves body, gloss and hardness. Because of their good pigment wetting and very low solution viscosity, KYA-81, KY-120 can be used for the manufacture of pigment pastes with a high pigment content. KYA-81 is very stable to heat and can be used in baking finishes, neither causing odor now discoloration. 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) Safety When handling these products, advice and information given in the safety data sheet must be complied with. Further, protective and workplace hygiene measures adequate for handling chemicals must be observed. R
