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.
