Description

2-Propenoic Acid, 2-Methyl-, 2-Hydroxyethyl Ester, Polymer With Phosphorus Oxide (P2O5) is a specialized polymeric material that combines the properties of a methacrylate ester with phosphorus-based chemistry. This unique copolymer is engineered to deliver enhanced flame retardancy and adhesion promotion in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to improve product performance and meet stringent safety regulations.

Application

• Flame Retardant Additive: A key component in intumescent coatings, paints, and sealants for construction materials, textiles, and electronics to meet fire safety standards (UL 94, ASTM E84).
• Adhesion Promoter: Enhances the bonding of coatings, inks, and adhesives to difficult substrates like metals, plastics, and treated surfaces.
• Crosslinking Agent: Used in radiation-curable (UV/EB) resins and thermosetting systems to improve hardness, chemical resistance, and durability of the final film.
• Dental & Medical Materials: Serves as a functional monomer in dental composites and bone cements, contributing to mechanical strength and hydrolytic stability.
• Optical Lens Resins: Imparts high refractive index and impact resistance in formulations for eyeglass lenses and optical components.
• Engineering Plastics Modifier: Incorporated into polymer blends and composites to tailor flame retardant and mechanical properties.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including phosphorus content, acid value, viscosity, and monomer residue. A comprehensive Certificate of Analysis (COA) documenting purity, identity, and key functional properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and polymerization. Keep away from heat and incompatible materials such as strong bases and oxidizing agents.
