1.Used in solvent-based coating systems with excellent defoaming ability and can quickly break foam.
2. Excellent defoaming and deaeration agent, which can effectively inhibit the formation of bubbles in the production and application of coatings, especially suitable for epoxy resin systems.
3. Helps to prevent and eliminate defects such as fisheyes, pinholes, craters and dark bubbles in the coating film.
4. Has good compatibility and is not easy to cause defects in the paint film.
Scope of application:
Can be used in all solvent-based and solvent-free coating systems.
Suggested Dosage:
Generally, 0.2-1% of the total amount of the system, in order to obtain excellent results, the defoamer should be added to the abrasive before grinding. If added at a later stage, a sufficiently high shear force is required to ensure adequate dispersion of the defoamer to prevent cratering.
