German technical background VOK®-W-77 water-based wetting agent

Product introduction: VOK®-W-77 surface tension regulator can be used as a buffer medium between high surface tension and low surface tension interfaces, whether between coating and coating or between coating and substrate. It can effectively eliminate or reduce coating defects such as uneven surface coating, fish eyes, shrinkage holes, etc. VOK®-W-77 can also promote the uniform coating of the coating on the surface of the substrate that is difficult to be wetted or contaminated, and provide good recoating property. VOK®-W-77 does not contain alkylphenol ethoxy compounds and organosilicon.

Application fields: water-based industrial coatings, water-based inks, adhesives.

Main characteristics: it will not cause poor adhesion between coatings. Improve the wettability of the substrate. Reduce film defects caused by low surface tension additives. Improve paint flow and leveling.

Amount added: 0.25-1.00%
