Butyl acrylate-ethyl acrylate-methacrylic acid copolymer

Butyl acrylate-ethyl acrylate-methacrylic acid copolymer, identified by CAS 31069-81-5, is an acrylic terpolymer used to control flow behavior and surface performance in waterborne and solvent-based formulations.

It functions as a rheology modifier and surface modifier across coatings, adhesives, and printing systems. In architectural and industrial coatings, it controls viscosity and prevents sagging without compromising leveling or film clarity.

Adhesive and sealant formulators use it to tune open time and tack profile in pressure-sensitive and construction adhesive systems. In printing inks and overprint varnishes, it contributes to substrate wetting and print definition.

Plastic coatings and polymer dispersions benefit from its compatibility with acrylic binder systems, supporting adhesion to low-energy substrates. This copolymer is typically supplied as an aqueous dispersion or solution.

Concentration and pH are adjusted to suit formulation compatibility. Technical grade is the standard commercial offering, with specifications aligned to rheology modifier applications in industrial and decorative coatings.

Packaging is available in drums and IBC containers for industrial procurement volumes. This material ensures consistent performance across a wide range of industrial and commercial chemical applications.
