Ethyl acrylate-methacrylic acid-tert-butyl acrylate copolymer

Ethyl acrylate-methacrylic acid-tert-butyl acrylate copolymer (CAS 159666-35-0) is an acrylic terpolymer resin used to control rheology and modify surface properties in polymer-based formulations.

Where is Ethyl acrylate-methacrylic acid-tert-butyl acrylate copolymer used?

• Coatings: film-forming and viscosity-building agent for waterborne and solvent-based systems, with controlled film formation and improved surface leveling
• Architectural and industrial finishes
• Adhesives and sealants: tunes tack, cohesion and peel strength in pressure-sensitive and structural systems
• Printing and packaging: binder component supporting ink adhesion and substrate compatibility on flexible substrates
• Plastics compounding: surface modifier improving compatibility between polymer matrices and functional additives

Good to know: Specifications vary by molecular weight distribution and acid content; buyers should confirm these parameters against their application requirements.

Commercial specifications

• Technical grade standard; solution grades in selected organic solvents
