Description

Dicyclopentenyloxyethyl Acrylate CAS NO 65983-31-5 is a specialized acrylate monomer featuring a bulky, hydrophobic dicyclopentenyl group. This unique structure is critical for imparting exceptional properties such as high refractive index, low shrinkage, and excellent adhesion to various substrates in polymer formulations. It is an essential raw material for manufacturers in the coatings, adhesives, and advanced resin industries seeking to enhance product performance and durability.

Application

• UV-Curable Coatings and Inks: A key component for formulating high-performance, fast-curing coatings with excellent hardness, chemical resistance, and adhesion to plastics and metals.
• Optical Resins and Adhesives: Used to produce polymers with a high refractive index for optical lenses, fiber optics, and LED encapsulants.
• Pressure-Sensitive Adhesives (PSAs): Enhances tack, peel strength, and cohesive strength in acrylic-based adhesive tapes and labels.
• Dental and Biomedical Composites: Employed in resin systems for dental fillings and restorative materials due to its low polymerization shrinkage and biocompatibility.
• Engineering Plastics and Modifiers: Acts as a reactive diluent and modifier to improve the flexibility, weatherability, and impact resistance of thermosetting resins.
• Printing Plate Resins: Utilized in photopolymer plates for flexographic and letterpress printing, offering high resolution and durability.

Quality Control

Our Dicyclopentenyloxyethyl 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 inhibitor levels. Certificates of Analysis (COA) documenting all critical 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, dry, well-ventilated area at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent polymerization and oxidation. Keep away from heat, sparks, and open flame. For long-term storage, monitor inhibitor levels as recommended.
