01Overview
Octylphenol ethoxylate (35 EO)
X-405 Wetting Agent (Octylphenol ethoxylate 35 EO) is a high-performance wetting additive specifically formulated for latex paint systems. It effectively prevents color floating and mottling, greatly enhances the freeze-thaw and mechanical stability of emulsions, and improves substrate wetting performance. The recommended dosage is 0.1%-0.4%; excessive addition may compromise the water resistance of the paint film. This agent is suitable for interior and exterior latex paints, high-PVC pigment systems, and carbon black pastes. However, as it belongs to the APEO category of surfactants, alternative products are required for premium eco-friendly formulations.
