Description

2-Propenoic Acid, 2-Methyl-, C12-20-Alkyl Esters, Polymers With 2-(Dimethylamino)Ethyl Methacrylate And Me Methacrylate is a specialized acrylic copolymer designed to provide unique performance characteristics in demanding formulations. This polymer is valued for its ability to impart excellent film formation, adhesion, and specific rheological properties. It is primarily used by manufacturers in the coatings, adhesives, and specialty chemical industries seeking advanced additive solutions.

Application

• As a film-forming agent and rheology modifier in industrial and architectural coatings.
• Key component in pressure-sensitive adhesives (PSAs) and laminating adhesives to enhance tack and cohesion.
• Functional additive in printing inks to improve gloss, laydown, and substrate adhesion.
• Used as a dispersant and stabilizer in pigment concentrates and resin systems.
• Base polymer for formulating specialty overprint varnishes and sealants.
• Modifier in textile and leather finishing chemicals to provide softness and durability.

Quality Control

Our polymer products are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solids content, viscosity, pH, and amine value. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong alkalis and incompatible organic solvents. For long-term storage, ensure containers are properly sealed to prevent skinning or evaporation.
