Wetting Agents
FEATURES
General Properties: Low molecular weight surfactants (anionic or nonionic); typically clear, low-viscosity liquids.
Synergistic Role: Wetting agents lower surface tension to penetrate dry powders but simultaneously stabilize the resulting foam. The defoamer must quickly knock down this foam without causing the wetted particles to re-agglomerate or float.
Performance Benefits:
Rapid Deaeration: Quickly releases air displaced from powder pores during the wetting and grinding process.
Prevents Flocculation: Maintains particle dispersion while eliminating foam, ensuring color strength and coating stability.
Defect-Free Coatings: Prevents craters and foam-induced pinholes in applied architectural paints and liquid membranes.
