Description

2-Propenoic Acid Polymer With Ethenylbenzene And (1-Methylethenyl)Benzene, Compd. With 2-Aminoethanol CAS NO 219916-89-9 is a specialized polymer compound, specifically an aminoethanol salt of an acrylic-styrene copolymer. This material matters for its unique combination of film-forming, binding, and dispersing properties derived from its polymeric structure and functional amine group. It is primarily needed by formulators in the coatings, adhesives, and specialty chemical industries seeking advanced performance additives.

Application

• As a film-forming agent and binder in water-based industrial and architectural coatings.
• As a dispersing aid and stabilizer for pigments and fillers in paint and ink formulations.
• As a key component in the production of pressure-sensitive adhesives (PSAs) and sealants.
• As a rheology modifier to control the flow and application properties of complex fluid systems.
• In the formulation of textile auxiliaries and fabric coatings for improved handle and durability.
• As a functional additive in paper coatings to enhance gloss, printability, and barrier properties.
• Potential use as an encapsulation matrix or carrier for active ingredients in agrochemicals or pharmaceuticals.
