Description

Dicaprolactone 2-(Acryloyloxy)Ethyl Este R is a specialized acrylate-functional monomer derived from caprolactone, designed for advanced polymer synthesis. This compound matters for its ability to introduce both hydrophobic caprolactone segments and reactive acrylate groups into polymer chains, enabling precise control over material properties like flexibility, adhesion, and cross-linking density. It is primarily needed by formulators and researchers in the coatings, adhesives, and advanced resin industries seeking to develop high-performance, tailored materials.

Application

• As a key monomer in the synthesis of UV-curable resins and coatings for wood, plastic, and metal substrates.
• In the formulation of pressure-sensitive and structural adhesives to enhance flexibility and environmental resistance.
• For modifying acrylic polymers to improve impact resistance, weatherability, and adhesion properties.
• As a reactive diluent and cross-linker in radiation-curable inks and overprint varnishes.
• In the production of specialty elastomers and sealants requiring a balance of toughness and low-temperature flexibility.
• For biomedical applications, such as in the development of photopolymerizable hydrogels or drug delivery matrices.
• In the manufacture of advanced composites and fiber-reinforced plastics to optimize the polymer matrix interface.

Quality Control

Our Dicaprolactone 2-(Acryloyloxy)Ethyl Este R is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC and impurity profiling, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

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 light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize polymerization. Keep away from heat, sparks, and open flame.
