VOK ®- W-77 promotes the wetting and spreading of paint solution to the substrate, and eliminates or improves surface defects. It does not affect the adhesion between layers.

Product introduction: VOK ®- W-77 surface tension regulator can be used as a buffer medium between high surface tension and low surface tension interfaces, either between coatings or between coatings and substrates. It can effectively eliminate or reduce coating defects such as uneven surface coating, fish eye, shrinkage cavity, etc. German technical background Volcker VOK ®- W-77 can also promote uniform coating of coatings on difficult to wet or contaminated substrate surfaces and provide excellent recoating. VOK ®- DAPRVOK W-77 contains no alkyl phenol ethoxy compounds and organic silicon.

Applications: 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 the fluidity and leveling of paint.

Amount added: 0.25-1.00%
