2,2,4-Trimethyl-1,3-Pentanediol Monoisobutyrate

2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate is a high-boiling, slow-evaporating ester alcohol renowned as an extremely efficient coalescing agent for aqueous polymer dispersions. By temporarily softening polymer particles, it facilitates their fusion into a continuous, tough, and durable film at lower temperatures, which is critical for achieving optimal performance in interior and exterior architectural and industrial latex paints.

    As a highly effective coalescing agent, C-12 Alcohol Ester is essential in water-based latex paints. It softens polymer particles during the drying process, allowing them to fuse into a continuous, durable film at ambient temperatures. This results in coatings with improved scrub resistance, gloss development, and overall durability without compromising environmental compliance.

  • Inks & Adhesives: Enhancing Performance
    Inks & Adhesives: Enhancing Performance

    In printing inks and adhesive formulations, this ester acts as a powerful plasticizer and solvent. It improves the flexibility and adhesion of polymer films, enhances pigment wetting, and helps maintain open time in adhesives. Its low volatility ensures consistent performance during application and curing processes.

  • Ore Flotation: Mineral Processing Aid
    Ore Flotation: Mineral Processing Aid

    C-12 Alcohol Ester serves as an effective flotation agent in mineral processing operations. It helps separate valuable minerals from gangue by modifying surface properties and enhancing bubble mineralization. This application is particularly valuable in the beneficiation of metallic ores and industrial minerals.

  • Industrial Cleaners: Controlled Solvency
