Description

Glyceryl Propoxy Triacrylate is a specialized multifunctional acrylate monomer known for its high reactivity and ability to form cross-linked polymer networks. This compound is essential for creating durable, high-performance coatings, inks, and adhesives with enhanced chemical resistance and mechanical properties. It is primarily sought after by formulators in the UV-curable resins, advanced coatings, and specialty polymer industries who require materials that deliver fast curing times and excellent final product performance.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, as well as graphic arts and packaging inks, enabling rapid curing and high gloss.
• Photopolymer Resins: Used in the production of photopolymers for 3D printing (stereolithography) and printing plates, contributing to precise detail and stability.
• Adhesives & Sealants: Imparts strong adhesion and cross-linking density in structural adhesives, pressure-sensitive adhesives (PSAs), and anaerobic sealants.
• Fiber Optic Coatings: Employed in coatings for optical fibers to provide protective, flexible, and durable layers that maintain signal integrity.
• Dental & Medical Composites: Serves as a cross-linking agent in restorative dental composites and bone cements, offering biocompatibility and strength.
• Electronics Encapsulation: Used in potting compounds and conformal coatings to protect electronic components from moisture and environmental stress.

Quality Control

Our Glyceryl Propoxy Triacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets precise industry and customer specifications. Certificates of Analysis (COA) documenting purity, color, acid value, and inhibitor content are provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, maintaining an inert gas (nitrogen) blanket in the headspace of the container is recommended to prevent polymerization.
