Description

1,2,3-Propanetriyl Triacrylate is a trifunctional acrylate monomer, also known as glyceryl triacrylate, characterized by its high reactivity and ability to form cross-linked polymer networks. This compound is essential for creating durable, high-performance coatings, adhesives, and resins with excellent chemical resistance and hardness. It is a critical raw material for manufacturers in the UV-curable coatings, photopolymer printing plates, and specialty polymer industries seeking to enhance product durability and performance.

Application

• Primary cross-linking agent in UV-curable inks, coatings, and adhesives for rapid curing and high surface hardness.
• Key monomer in the production of photopolymer resins for flexographic printing plates and 3D printing.
• Used in the synthesis of highly cross-linked acrylic polymers for optical lenses and medical devices.
• Component in radiation-curable oligomers for wood, plastic, and metal finishes.
• Employed in adhesive formulations to improve bond strength and thermal stability.
• Used in fiber optic coatings and electronic encapsulants for protective properties.

Quality Control

Our 1,2,3-Propanetriyl Triacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, and acid value. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Incompatible with strong acids and oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
