Description

2-(Phosphonooxy)Propane-1,3-Diyl Bismethacrylate is a specialized, high-purity functional monomer containing both methacrylate and phosphonate ester groups. This unique bifunctional structure makes it a critical cross-linking agent and adhesion promoter in advanced polymer formulations. It is essential for manufacturers in the dental materials, biomedical device, and high-performance coatings industries seeking to enhance material durability, biocompatibility, and bonding strength.

Application

• Dental Restorative Composites & Cements: A key monomer in self-etching and self-adhesive dental materials, improving bond strength to tooth enamel and dentin.
• Biomedical Hydrogels & Bone Cements: Used to create cross-linked polymer networks with controlled degradation and enhanced biocompatibility for tissue engineering and orthopedic applications.
• Adhesive Primers & Coatings: Functions as an adhesion promoter on difficult substrates like metals and ceramics, particularly in dental and industrial bonding systems.
• UV-Curable Resins & Inks: Serves as a reactive diluent and cross-linker in formulations requiring fast curing, high hardness, and chemical resistance.
• Ion-Exchange & Chelating Polymers: Incorporated into resins for water treatment and metal recovery due to the phosphonate group's metal-binding capability.
• Contact Lens & Ophthalmic Materials: Used in the synthesis of hydrogels with high oxygen permeability and desirable mechanical properties.

Quality Control

Every batch of 2-(Phosphonooxy)Propane-1,3-Diyl Bismethacrylate is produced and tested under a strict quality management system. We ensure high purity and consistency suitable for sensitive applications like dental and biomedical manufacturing. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place (recommended 2-8°C or as specified on the label) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and polymerization. Keep away from heat, sparks, and open flame. The container must be kept tightly closed in a dry and well-ventilated place.
