Hemispherx Levaslip 8629 Polyether Modified Polysiloxane Leveling Agent
Product Description
Hemispherx Levaslip 8629 is a polyether-modified polysiloxane flow agent that enhances both solvent-based and solvent-free coating systems. It improves flow and leveling while eliminating surface defects like orange peel and craters. The additive also provides anti-blocking properties and excellent substrate wetting for uniform film formation.
