German technical background VOK-Disponer W-518 Wetting dispersant Improve surface defects replaces Elementis Disponer W-518

German technical background VOK?- Dispener W-518 wetting dispersant

Product name: VOK?- Dispener W-518 wetting dispersant

Main ingredients: Polyacrylate amine salt

Active ingredient: 30

Add%: 1-2 (for inorganic pigments and fillers)//4-8 for iron oxide series

Main function: provide dispersion stability of inorganic pigment fillers

Application field: architectural coatings, other water-based systems

VOK?- W-77 promotes the wetting and spreading of the paint solution on the substrate, and improves the 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, whether between coating and coating or between coating and substrate. It can reduce coating defects such as uneven surface coating, fisheye, shrinkage hole, etc. German technical background Volcker 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?- DAPRVOK 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%
