Description

5-Decyne-4,7-Diol, 2,4,7,9-Tetramethyl-, Polymer With Oxirane is a specialized nonionic surfactant and defoamer intermediate, known for its unique acetylenic diol structure modified with polyoxyethylene (POE) chains. This chemistry provides exceptional wetting, leveling, and foam control properties in demanding formulations. It is a critical performance additive for industries requiring advanced surface activity and process stability, particularly in high-solids and water-based systems.

Application

• Primary defoamer and air-release agent in water-based industrial coatings, inks, and adhesives.
• High-performance wetting and leveling agent for architectural and automotive paint formulations.
• Key surfactant component in agricultural chemical formulations (pesticides, herbicides) to enhance spreading and penetration.
• Processing aid and foam suppressant in the manufacture of polyurethane foams and other polymer dispersions.
• Dispersing and grinding aid for pigment concentrates and fillers.
• Additive for metalworking fluids and industrial cleaners to improve surface contact and reduce foam.
• Component in paper coating formulations to control foam and improve finish quality.
• Intermediate for the synthesis of further customized surfactant and specialty chemical products.
