Description
2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate (CAS 25265-77-4) is a slow-evaporating coalescent solvent commercially known as Texanol, CS 12, CS12, NX 795, and Ester 12. It carries no E-code designation and is classified under HS code 29156000.
In waterborne architectural coatings, it lowers the minimum film formation temperature of latex binders, allowing polymer particles to coalesce into a continuous film at ambient temperatures. In adhesives and sealants, it functions as a plasticising solvent that improves substrate wetting and extends open time, while in printing inks it supports rheology control by moderating viscosity during application.
The material is supplied as a standard industrial-grade clear liquid and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm SDS compliance and confirm packaging formats, typically available in drums and IBCs, with the supplying distributor prior to order placement.
