Typical applications
1. water-based coatings, adhesives, inks, varnishes
2. Wetting/reducing surface tension (dynamic static)
3. For surface defects require more strict coating film, can prevent shrinkage, pinhole, fish eye
4. Effectively eliminate micro bubbles and low bubbles in the system, and inhibit the foaming performance of water-based system
Application matters
1. recommended addition amount 0.1-1%
2. High speed stirring is required for 30 minutes during use
