Description

3,3,5-Trimethylcyclohexyl Acrylate is a specialized acrylate monomer featuring a bulky, sterically hindered cyclohexyl group. This compound is valued for its ability to impart unique properties to polymer chains, such as enhanced hydrophobicity, improved chemical resistance, and lower glass transition temperatures. It is primarily sought after by formulators and polymer chemists in the coatings, adhesives, and advanced materials sectors for developing high-performance, tailored resins.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and crosslinking agent to formulate low-viscosity, fast-curing systems with excellent surface hardness and weatherability.
• Pressure-Sensitive Adhesives (PSAs): To modify tack, peel strength, and shear resistance in acrylic adhesive formulations.
• Specialty Acrylic Polymers: As a co-monomer to introduce steric hindrance, improving solubility in organic solvents and resistance to hydrolysis and chemicals.
• Fiber-Reinforced Composites: In resin matrices for composites requiring low shrinkage upon curing and good mechanical properties.
• Photopolymer Resins: For 3D printing (stereolithography) and photoresists, where precise polymerization control and final material properties are critical.
• Modifier for Synthetic Rubbers & Elastomers: To enhance low-temperature flexibility and processing characteristics.

Quality Control

Our 3,3,5-Trimethylcyclohexyl Acrylate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications, including purity, identity, and absence of critical impurities like polymerization inhibitors at specified levels. Certificates of Analysis (COA) documenting these results are provided and 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 at room temperature (15-25°C/59-77°F). Due to its highly volatile and light-sensitive nature, containers must be kept tightly sealed when not in use to prevent evaporation and potential quality degradation. Keep away from heat, sparks, and open flame.
