Detailed introduction

KY-A101  High softening point Aldehyde Resin

 

KY-A101 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.

Application

 

● Because of their excellent solubility and compatibility, KY-A101 can be used in many types of ink/coating formulations.

 

● Depending on the application, KY-A101 improves the gloss, hardness, adhesion, and resistance to yellowing of coating.

 

● Because of their good pigment wetting, KY-A101 can be used for the manufacture of pigment pastes with high pigment content.

 

● KY-A101 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).

 

● Comparing with KY-A81, KY-A101 showed more obvious improvement in gloss, hardness and dryness, but compatibility was not good as KY-A81.


 

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.
