Description

2-Octyl Acrylate Polymer is a synthetic polymer derived from the monomer 2-octyl acrylate, known for its long alkyl side chain. This structure imparts excellent hydrophobic properties, flexibility, and low-temperature performance to the final material. It is a key raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product durability and water resistance.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and water resistance in label and tape formulations.
• Industrial & Protective Coatings: Used as a film-forming agent to improve flexibility, adhesion, and moisture barrier properties.
• Sealants and Caulks: Enhances elasticity, durability, and weather resistance in construction and automotive applications.
• Textile and Leather Finishes: Provides a soft, hydrophobic coating to improve feel and stain resistance.
• Printing Inks: Contributes to ink adhesion and rub resistance on non-porous substrates.
• Modifier for Other Polymers: Used as an additive to plasticize or improve the compatibility and performance of other polymer systems.

Quality Control

Our 2-Octyl Acrylate Polymer is manufactured under a strict quality management system. Each batch is tested for critical parameters including molecular weight distribution, residual monomer content, viscosity, and appearance to ensure consistent performance in your formulations. Certificates of Analysis (COA) are available upon request.

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.
