Description

sec-Butyl Acrylate is a versatile and reactive acrylate ester monomer. This compound is a critical building block in the production of polymers and copolymers, valued for its ability to impart flexibility, low-temperature properties, and weatherability to final materials. It is essential for manufacturers in the coatings, adhesives, textiles, and plastics industries seeking to enhance product performance.

Application

• Acrylic Resin Synthesis: A key monomer for producing solution, emulsion, and solvent-based acrylic polymers.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack and peel adhesion properties essential for label and tape formulations.
• Surface Coatings & Paints: Used in automotive, industrial, and architectural coatings to improve flexibility, gloss, and durability.
• Textile & Leather Finishes: Employed in binders and finishing agents to provide soft hand feel and water resistance.
• Plastic Modifiers: Acts as a co-monomer to modify the impact strength and processability of engineering plastics.
• Paper Coatings: Enhances the gloss, printability, and barrier properties of coated paper and paperboard.
• Sealants & Caulks: Contributes to the elasticity and adhesion of construction and automotive sealants.

Quality Control

Our sec-Butyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and inhibitor content. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, ignition points, and incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is 15-25°C. The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization; monitor storage conditions to maintain inhibitor efficacy.
