WL-181 is a kind of water based saturated polyester resin,and can be diluted by deionized water infinitely.It is stable under alkaline condition,so the diluted resin and lacquer shall be stored under weak alkaline condition.The viscosity of the emulsion will increase as the pH value increases.
The diluted emulsion has the excellent shear stability,and therefore can directly be used in pigment paste grinding.After crosslink with amino,the paint film has excellent hardness and flexibility,high gloss,and high fullness,and therefore can be used for highly decorative top coatings,such as all kinds of hardness metal surfaces or wood surfaces.
The etherfied water based amino is recommend for crosslinking.The consumption is 35-40%of the resin consumption,and the baking temperature is above 130℃.
