Ink Leveling Agent
CAS Number: 67674-67-3
A polyether-modified polydimethylsiloxane leveling agent that reduces surface tension gradients in drying ink films to eliminate orange peel, pinholes, and brush marks. It migrates efficiently to the ink-air interface to provide uniform surface tension across the film, resulting in excellent leveling and flow. The controlled surface activity minimizes foam and does not adversely affect intercoat adhesion.
