High solid primer defoamer BYK-1790 for solvent-based coatings/ light-curing coatings/ solvent-free coatings
Technical Data Sheet
High solid primer defoamer BYK-1790
Composition:Pure acrylic polymer
Typical Physical Data
| BYK-1790 | Appearance | Active portion | Solvent |
| Colorless to light yellow liquid | 75％ | xylene |
Application : solvent-based coatings; light-curing coatings, solvent-free coatings.
Recommended dosage: 0. 1–0.5% of the total formula (please test the most appropriate dosage before use)
Usage: In order to obtain sufficient defoaming effect, it is recommended to add it before grinding. If added later, mix under sufficiently high shear to ensure defoaming.
Features and advantages: BYK-1790 has excellent defoaming and anti-foaming effects, which can inhibit and eliminate the bubbles generated during the production, canning and construction of coatings, especially for the bubbles generated by the reaction of two-component coatings and high zinc stearate The defoaming effect in the formula is remarkable. Since BYK-1790 has an incomparable defoaming effect with other types of defoamer, it is very effective in primers.
Packaging: 25kg /drum. The product is completely unused before use, and the inner and outer covers must be tightly closed after use.
