Description

2,4,7,9-Tetramethyl-5-Decyne-4,7-Diol Ethoxylate is a high-performance, non-ionic surfactant and wetting agent belonging to the acetylenic diol ethoxylate family. Its unique branched structure provides superior dynamic surface tension reduction and excellent foam control, making it a critical additive in formulations requiring rapid wetting and leveling. This product is essential for manufacturers in the coatings, inks, adhesives, and agrochemical industries seeking to enhance application properties and final product performance.

Application

• Coatings & Inks: As a highly effective wetting and dispersing agent for pigments and fillers, improving color development, gloss, and preventing flooding and floating.
• Adhesives & Sealants: To enhance substrate wetting and spreadability, ensuring strong adhesion and uniform film formation.
• Agrochemical Formulations: As a key component in pesticide and herbicide sprays, providing superior wetting and spreading on waxy leaf surfaces for increased efficacy.
• Industrial Cleaners: Used in metal cleaning and degreasing formulations for its low-foaming characteristics and ability to wet oily surfaces quickly.
• Paper & Textile Processing: As a defoamer and leveling agent in coating formulations and dye baths.
• UV-Curable Systems: Employed as a surfactant to improve substrate wetting and compatibility in radiation-curable coatings and inks.
