Description

Ethoxylated Propoxylated 2,4,7,9-Tetramethyl-5-Decyne-4,7-Diol is a high-performance, non-ionic surfactant and defoamer derived from a unique acetylenic diol chemistry. This compound is engineered to provide exceptional wetting, leveling, and foam control properties in demanding formulations. It is a critical additive for manufacturers in the coatings, inks, adhesives, and agrochemical industries seeking to improve process efficiency and final product performance.

Application

• Coatings & Inks: Acts as a powerful wetting and leveling agent for water-based and solvent-based systems, reducing surface defects and improving substrate adhesion.
• Adhesives & Sealants: Enhances spreadability and penetration while controlling foam generation during mixing and application processes.
• Agrochemical Formulations: Used as a surfactant and tank-mix adjuvant in pesticides and herbicides to improve droplet spread and coverage on leaf surfaces.
• Industrial Cleaners: Provides effective wetting and defoaming in acidic or alkaline cleaning solutions for metal treatment and institutional cleaning.
• Polymerization: Serves as a surfactant and foam suppressant in emulsion polymerization processes for acrylics, vinyl acetates, and styrene-butadiene.
• Paper & Textile Processing: Aids in dye leveling, pigment dispersion, and foam control in various wet-processing stages.
