Description

2-Propenoic acid, 2-methyl-, butyl ester, polymer with 2-(dimethylamino)ethyl 2-methyl-2-propenoate, dodecyl 2-methyl-2-propenoate, eicosyl 2-methyl-2-propenoate, hexadecyl 2-methyl-2-propenoate, octadecyl 2-methyl-2-propenoate, pentadecyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed for advanced industrial applications. This specialized polymer offers a unique balance of properties derived from its carefully selected monomer composition, including long-chain alkyl acrylates for hydrophobicity and a dimethylaminoethyl acrylate for functionality. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability, compatibility, and performance. The compound is identified by CAS No. 70851-55-7.

Application

• Industrial and Protective Coatings: Used as a key resin or additive to improve film formation, water resistance, and adhesion to various substrates in metal, wood, and plastic coatings.
• Pressure-Sensitive Adhesives (PSAs): Serves as a base polymer to provide tack, peel strength, and shear resistance in label, tape, and graphic film adhesives.
• Textile and Leather Finishes: Imparts water repellency, soft hand feel, and durability as a finishing agent or coating binder.
• Printing Inks: Enhances pigment wetting, gloss, and rub resistance in solvent-based and overprint varnish formulations.
• Rheology Modifiers and Thickeners: Functions as an associative thickener in aqueous systems to control viscosity and flow properties.
• Specialty Additives: Utilized as a dispersing agent, compatibilizer, or performance additive in sealants, caulks, and polymer blends.

Quality Control

Our production of this advanced acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for your formulations. Key parameters such as solid content, viscosity, acid value, amine value, and glass transition temperature (Tg) are rigorously controlled and tested. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to guarantee compliance with your technical requirements.

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 heat sources and open flame. For long-term storage, consider under an inert atmosphere to prevent oxidation. Keep container tightly sealed when not in use to prevent moisture absorption or solvent loss.
