Description

Hpma CAS NO 38130-86-8 is a high-purity chemical intermediate, specifically 2-Hydroxypropyl methacrylate, valued for its reactive methacrylate and hydroxyl functional groups. This dual functionality makes it a critical building block for creating advanced polymers with tailored properties. It is essential for manufacturers in the coatings, adhesives, and specialty materials sectors seeking to enhance product performance, durability, and application versatility.

Application

• UV-Curable Coatings & Inks: A key monomer for formulating fast-curing, high-gloss, and scratch-resistant surface coatings and printing inks.
• Acrylic Resin Modification: Used to introduce hydroxyl groups into acrylic copolymer chains, improving adhesion to various substrates and crosslinking potential.
• Hydrogel Synthesis: Serves as a co-monomer in the production of hydrophilic polymers for contact lenses, wound dressings, and drug delivery systems.
• Adhesive & Sealant Formulations: Enhances the flexibility, water resistance, and bonding strength of acrylic-based adhesives and sealants.
• Dental & Biomedical Materials: Employed in the manufacture of dental composites and bone cements due to its biocompatibility and polymerizable nature.
• Fiber Optic Coatings: Used in coatings that protect optical fibers, providing essential mechanical strength and environmental protection.

Quality Control

Our Hpma is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis via HPLC and GC, to ensure it meets exacting specifications. A Certificate of Analysis (COA) documenting all critical parameters is provided with each shipment to guarantee traceability and compliance.

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). Keep away from heat sources and incompatible materials such as strong oxidizers and bases. For long-term storage, under an inert atmosphere such as nitrogen is recommended to prevent premature polymerization.
