Crude Sulphate Turpentine (CST)

Crude Sulphate Turpentine (CST) is a by-product of the Kraft pulping process, obtained by treating crude turpentine with sulphuric acid. CST is a complex mixture of modified terpene compounds formed through acid-catalyzed reactions. It serves as a raw material for producing various specialty chemicals and refined turpentine derivatives. CST is typically supplied in liquid form, with a color ranging from amber to dark brown, and it exhibits a viscous, resinous texture.

Crude Sulphate Turpentine (CST) enhanced stability, reduced volatility, and improved compatibility with resin systems make it a valuable ingredient in several industrial applications:

Adhesives and Sealants

CST improves the formulation of high-performance adhesives and sealants, contributing to stronger bonds and enhanced durability.
 

Coatings and Printing Inks
Acting as a solvent and processing aid, it promotes superior film formation, gloss, and controlled drying times.
 

Rubber Formulations

Its plasticizing properties enhance processability and performance in rubber compounding, resulting in improved elasticity and resilience.
