TEGO Wet 270 Silicone-Based Substrate Wetting Agent for Medium-to-High-Polarity Coatings & Inks

Full Name: TEGO Wet 270 Silicone‑based Substrate Wetting Additive Substrate wetting agent tailored for medium‑to‑high‑polarity resin systems. Improves substrate spreading and suppresses crater defects for coatings, inks and selected varnish systems. Core Technical Parameters Test Item Typical Value Chemical Composition Modified silicone‑based surfactant Active Content 100% Appearance Clear liquid Viscosity (25℃) 120‑240 mPa·s Standard Package 25 kg plastic drum, 200 kg steel drum Key Advantages 1.  Effectively lowers surface tension, enhances spreading performance over various hard‑to‑wet substrates. 2.  Matches medium‑to‑high‑polarity resins with prominent crater‑suppression effect. 3.  Controllable foaming behaviour, compatible with spray‑coating and roll‑coating application methods. 4.  Good compatibility with most acrylic, polyurethane and epoxy resins. 5.  Can be used synergistically with defoamers to optimise manufacturing processes. Main Application Fields Core Applications: Water‑borne industrial topcoats, wood coatings, printing varnishes, plastic coatings Suitable Applications: Primers, selected architectural industrial tinting colour‑paste systems Restriction: Do not apply to food‑contact articles without valid compliance certification.
