Description

3,5,5-Trimethylhexyl Acrylate is a high-purity, branched-chain alkyl acrylate monomer valued for its ability to impart low-temperature flexibility, hydrophobicity, and excellent weathering resistance to polymer chains. This compound is a critical raw material for synthesizing advanced polymers and copolymers with tailored performance characteristics. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for the production of specialty plastics and additives.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts low-temperature flexibility and improved tack, essential for tapes and labels.
• Coatings and Paints: Used in acrylic resin formulations to enhance water resistance, durability, and gloss retention in automotive, industrial, and architectural coatings.
• Sealants and Caulks: Provides elasticity and adhesion to acrylic-based sealants used in construction and automotive applications.
• Elastomers and Rubber Modification: Acts as a co-monomer to improve the low-temperature performance and processing of synthetic rubbers.
• UV-Curable Resins & Inks: Serves as a reactive diluent or monomer in formulations for fast-curing, high-performance inks and coatings.
• Plastic Additives: Used to manufacture impact modifiers and processing aids for engineering plastics.
• Textile and Leather Finishes: Incorporated into polymers for durable, flexible, and water-repellent finishes.
• Specialty Monomers for R&D: A key intermediate for chemical synthesis in pharmaceutical and agrochemical research.

Quality Control

Our 3,5,5-Trimethylhexyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and assay, to ensure it meets precise specifications for monomer content and impurity profiles. Certificates of Analysis (COA) detailing all test results are provided with each shipment to guarantee traceability, consistency, and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent polymerization and oxidation. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents.
