Product Description

Texanol ester alcohol is the premier coalescent for latex paints. It performs well in all types of latex paints, in a variety of weather conditions, and over substrates with different levels of porosity. Texanol provides the highest level of film integrity at low levels of coalescent, enhancing the performance properties of the paint including low temperature coalescence, touch-up, scrub resistance, washability, color development, thermal flexibility, and resistance to mudcracking. Texanol also enhances thickening efficiency when used with associative thickeners.

Texanol also works well in a variety of other applications. It is an ideal choice as a retarder solvent for use in coil coatings and high-bake enamels. Texanol offers a good balance of performance properties for ink applications requiring good open. The unique balance of properties in Texanol also makes it useful for a variety of chemical specialty applications such as ore flotation / frothing, oil-drilling muds, wood preservative carriers, and floor polishes.

Texanol can also be used as a solvent in nail polish. The INCI (cosmetic ingredient) name for Texanol Ester Alcohol is Trimethyl Hydroxypentyl Isobutyrate.

Due to its non-VOC status, low toxicity, and biodegradability, Texanol ester alcohol has been awarded Green Label Type II certificate in China by the China Environmental United Certification Co. Ltd. (CEC), a wholly-owned subsidiary of the State Environmental Protection Administration of China (SEPA).

Texanol is one of the Eastman Coatings Film Technologies portfolio of products and one of the many Eastman solvent replacements for ExxonMobil¡¯s discontinued Exxate solvents.
