What is Texanol?
Texanol (CAS 25265-77-4), also known as 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, is a slow-evaporating ester alcohol solvent used primarily as a coalescent agent in waterborne coating systems.
Where is Texanol used?
- Architectural and industrial waterborne paints: benchmark coalescent
- Acrylic and vinyl-acrylic latex systems: improves film formation without permanently softening the dried coating
- Printing inks: rheology modifier and carrier solvent
- Water-based flexographic and gravure inks: controls flow and open time
- Construction adhesives and sealants: processing aid that improves substrate wetting and adhesion development
- Polymer dispersions, caulks and elastomeric sealants: extends working time
- It temporarily plasticizes latex particles during drying, enabling continuous, defect-free films at low application temperatures.
Good to know: Commonly referenced against Eastman's commercial standard in supplier qualification processes.
