Description

Poly(Styrene-Co-Maleic Acid), Partial Isooctyl Ester, Cumene Terminated is a synthetic copolymer designed to act as a versatile dispersant, emulsifier, and rheology modifier. This amphiphilic polymer is engineered to provide excellent compatibility and stability in complex formulations, particularly in non-aqueous systems. It is a critical component for industries requiring high-performance additives to control particle dispersion, viscosity, and film formation, such as advanced coatings, inks, and specialty adhesives.

Application

As a dispersing agent for pigments and fillers in solvent-based industrial and automotive coatings.
As a rheology modifier and stabilizer in high-solids and UV-curable ink formulations.
As a compatibilizer and emulsifier in adhesive and sealant systems to improve bonding and stability.
As an additive in lubricant and grease formulations to enhance dispersion of solid additives.
As a processing aid in polymer composites and masterbatches to improve filler incorporation.
In the formulation of agrochemical concentrates (e.g., suspension concentrates, oil dispersions) for improved active ingredient dispersion.
