Description

Phosphinylidynetris(Oxyethylene) Triacrylate is a specialized multifunctional acrylate monomer containing a central phosphorus atom. This compound matters for its ability to impart flame retardancy, adhesion promotion, and crosslinking density to polymer systems. It is primarily needed by formulators in the coatings, adhesives, and advanced resin industries seeking to enhance material performance.

Application

• As a reactive flame-retardant monomer in UV-curable coatings and inks for electronics and packaging.
• A key crosslinking agent in high-performance adhesives and sealants requiring improved thermal stability.
• In the synthesis of specialty photopolymers for optical films and 3D printing resins.
• As a modifier for dental composites and biomaterials to enhance mechanical properties.
• For producing flame-retardant fiber treatments and textile finishes.
• In the formulation of advanced composite matrices for aerospace and automotive applications.

Quality Control

Our Phosphinylidynetris(Oxyethylene) Triacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC and impurity profiling, to ensure it meets precise specifications for reactive monomer applications. Certificates of Analysis (COA) documenting purity, color, acid value, and moisture content 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, and well-ventilated place at 15-25°C under an inert atmosphere (e.g., nitrogen), as the material is easily oxidized and light-sensitive. Keep away from heat, sparks, and open flame. Isolate from strong oxidizing agents and bases.
