Description

Caprolactone Acrylate is a specialized acrylate monomer that combines the reactivity of an acrylate group with the unique properties of a caprolactone chain. This compound is valued for its ability to impart flexibility, toughness, and enhanced adhesion properties to polymer systems. It is primarily sought after by formulators in the coatings, adhesives, and advanced resin industries for developing high-performance, customizable materials.

Application

• UV-Curable Coatings & Inks: A key component in formulations requiring fast cure times, excellent surface adhesion, and improved flexibility for substrates like plastics, metals, and wood.
• Adhesives & Sealants: Used to modify acrylic-based adhesives, enhancing their impact resistance, elongation, and bonding strength on difficult surfaces.
• Specialty Resins & Polymers: Serves as a reactive diluent and modifier in the synthesis of polyester and acrylic resins, tailoring properties like viscosity, glass transition temperature (Tg), and weatherability.
• 3D Printing Resins: Incorporated into photopolymer resins for stereolithography (SLA) and digital light processing (DLP) to reduce brittleness and improve the durability of printed parts.
• Fiber Optic Coatings: Contributes to the production of flexible, protective secondary coatings for optical fibers, safeguarding against mechanical stress and environmental factors.
• Dental & Biomedical Materials: Utilized in the development of biocompatible, photocurable composites for dental restoratives and other medical device applications.

Quality Control

Our Caprolactone Acrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identity confirmation (IR), and measurement of key impurities (e.g., residual monomer, acid value, water content), to ensure it meets precise specifications for reactivity and performance. A Certificate of Analysis (COA) documenting these results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent polymerization and maintain purity. Keep away from heat, sparks, and open flame.
