Silicone-Free Wetting Agent for Adhesives
Silicone-free wetting agent based on modified polyether siloxane-free chemistry is used in waterborne and solvent-borne adhesive formulations to improve substrate wetting, reduce surface tension, and enhance adhesion to low-energy substrates. It lowers the dynamic contact angle on plastics, metals, and treated papers, enabling uniform adhesive spreading and eliminating crawling or fisheye defects. Silicone-free grades are preferred in systems where silicone contamination is undesirable, such as automotive painting lines.
