BZ-404 Antifoaming additive for primer
Composition: polymer solution
Typical physical data
Appearance: colorless transparent to yellowish liquid
Active ingredient: 27%
Solvent: xylene
Suitable for: solvent-based coatings; recommended for: 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, it should be mixed under high enough shear force to ensure the defoaming effect.
Characteristics and advantages:
- with excellent defoaming and foam inhibition effect, can inhibit and eliminate the air bubbles generated by the coating in the process of production, canning and construction, especially for the two-component coating reaction bubbles generated by the defoaming effect is extremely significant. Especially for the use of higher zinc stearate formulations in the anti-foaming effect is remarkable.
- Because BZ404 has the defoaming effect which is incomparable with other types of defoamers, it is used in primer with very good effect.
