New Additol VXW 6503 N universal wetting and leveling agent from Cytec Industries Inc. is a polyether modified siloxane that improves substrate wetting in a wide variety of aqueous, solventborne and solvent-free formulations, including UV/EB curable formulations.

The specific siloxane tenside structure used in Additol VXW 6503 N leads to superior dynamic surface tension reduction and improved static surface tension reduction, according to the company. As a result, Additol VXW 6503 N provides optimal substrate wetting and anti-cratering performance without contributing to foam stabilization or impacting intercoat adhesion.

In addition, this performance can be achieved at addition levels as low as 0.1 - 1.0 percent on total formulation, and Additol VXW 6503 N can be incorporated at any stage of the production process.
