2,2,4-TRIMETHYL-1,3-PENTANEDIOL MONOISOBUTYRATE | CAS 25265-77-4

Product Overview

2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate (CAS: 25265-77-4) is a high-boiling ester alcohol that functions as a slow-evaporating coalescing agent and solvent. It is a colorless liquid with a mild characteristic odor. This compound is widely recognized as the premier coalescent for latex paints and waterborne coating systems, providing excellent film formation, stability, and performance properties.

This product is commonly known by its trade names including Texanol, Texanol ester alcohol, and is also referred to as TMPD-MIB, Chissocizer CS-12, and Alcohol Ester-12.

Product Description

2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate is a colorless, transparent liquid with a mild odor. It serves primarily as a solvent and coalescent in various applications, particularly in paints, coatings, and adhesives. The compound is characterized by its excellent solvency properties, which enhance formulation performance by improving film formation and stability.

Key attributes include relatively low volatility, high boiling point, excellent hydrolytic stability, and good compatibility with a wide range of resins and polymers. The substance is slightly soluble in water (approximately 2 g/100ml) and easily soluble in most organic solvents such as chloroform and methanol. It has low toxicity and is often preferred in formulations where safety and environmental considerations are paramount.

Technical Specifications

Applications

Paints & Coatings

This compound is the most widely adopted coalescing agent for waterborne latex paints globally. It performs well in all types of latex paints across various weather conditions and over substrates with different porosity levels. The coalescent enhances paint performance properties including:

• Low temperature coalescence

• Touch-up and color development

• Scrub resistance and washability

• Thermal flexibility

• Resistance to mudcracking

As a slow-evaporating, water-insoluble coalescing aid, it provides good performance characteristics such as scrub resistance, color development, and package stability in paints. Its low water solubility ensures the coalescent remains in the polymer phase during drying on absorptive surfaces, a critical advantage for architectural paint formulators.

Adhesives & Sealants

Functions as a solvent and plasticizing additive in adhesive and sealant formulations, improving flexibility and application properties.

Printing Inks

Used as a solvent and coalescent in printing ink formulations to enhance flow, leveling, and film properties.

Cosmetics & Personal Care

Employed as a solvent in nail care products and other cosmetic formulations.

Pharmaceuticals

Utilized in the pharmaceutical industry as a formulation auxiliary.
