<p>A fluorocarbon anti-cratering levelling agent for coating and ink is made from the following raw materials: 5-90wt% of solvent, 5-90wt% of fluorine-containing acrylate monomer, 0.1-10wt% of initiator. The levelling agent has a surface tension of 21-24 dyne, a number-average molecular weight of 1500-4500, weight-average molecular weight of 3000-15000, and a polydispersity of 1.5-2.8. The levelling agent can reduce surface tension of coating system, and has good anti-cratering ability, and is excellent in long wave levelling property.</p> |
