Texanol
Texanol is the commercial name for 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, a high-performance coalescent and solvent widely used in latex paints, coatings, inks, and adhesives. It helps film formation at lower temperatures, enhances flow, improves gloss, and increases storage stability. Texanol is prized for its low odor, low volatility, and excellent balance between solvency and environmental compliance, making it a preferred coalescing agent in waterborne systems.
Primary Uses
Paints & Coatings Industry
Coalescing Agent: Essential in water-based paints to soften latex particles, enabling proper film formation during drying.
Gloss Enhancer: Improves surface appearance and gloss in decorative and industrial coatings.
Flow and Leveling Agent: Enhances application properties by promoting smoother surface finishes.
Low-VOC Formulations: Used in compliant coatings to reduce overall volatile organic compound (VOC) content.
Inks & Printing
Solvent in Water-Based Inks: Used to dissolve or disperse pigments, improve drying, and enhance print quality.
Film-Forming Additive: Aids in continuous film formation on substrates in waterborne ink systems.
Adhesives & Sealants
Plasticizer/Coalescent: Improves adhesion and flexibility in pressure-sensitive and construction adhesives.
Stabilizer: Prevents premature solidification and improves open time during application.
Secondary Uses
Textile Finishes
Binder Coalescent: Helps form flexible and durable films in textile coating and finishing formulations.
Cleaning Products
Solvent Additive: Occasionally used in specialty cleaning agents and polishes for its solvency and compatibility with aqueous systems.
Construction Materials
Binder Modifier: Used in construction emulsions and joint compounds to improve film integrity and workability.
