L89 leveling agent testing report

Wuhan Yincai Technology Co.,Ltd | Updated: Aug 22, 2017

L89 leveling agent is designed by Wuhan Yincai technology Co., ltd,. This leveling agent can effectively solve interfere problem when customer change flow additives in production. L89 also has stronger ability to overcome pitting and cratering, better leveling effect and distinctness of image.

 

In order to test the anti interference ability of different leveling agents, we choose the pure polyester system for test. First we use different brands of leveling agent to make base powder (formulation as below chart), then mix the different base powder with the ration from 1%-10% , thirdly judge the anti interference ability by the panels surface.

From above test we found: GLP 588 and FC 100 are less anti interference ability against PV 88 or P67.

Our leveling agent L89 is better anti interference ability against PV 88 or P67.
