PRODUCT OVERVIEW

Product Description

CS-12 Series 2,2,4-Trimethyl-1,3-Pentanediol Monoisobutyrate is a colorless and transparent diol ester liquid used primarily as a coalescing and film-forming aid in water-based systems. It combines low volatility, a high boiling point, and a low freezing point, making it suitable for emulsion polymer and coating formulations where efficient film formation is required. CS-12 helps reduce the minimum film-forming temperature of emulsion systems and supports the formation of stable, uniform films in applications such as latex paints, adhesives, emulsions, and architectural coatings.
