Description

Poly(2-Hydroxypropyl Methacrylate) is a versatile, hydrophilic methacrylate monomer derivative widely used in the production of specialty polymers. Its unique combination of a polymerizable methacrylate group and a hydroxyl functionality makes it a critical building block for creating materials with tailored properties. This compound is essential for manufacturers in the contact lens, biomedical device, adhesive, and advanced coating industries seeking to enhance biocompatibility, adhesion, and moisture retention in their products.

Application

• Hydrogel Manufacturing: A key monomer for producing soft contact lenses and wound dressings due to its high water-absorbing capacity and biocompatibility.
• Biomedical Coatings: Used to create hydrophilic, protein-resistant surfaces on medical devices and implants to improve biocompatibility.
• Adhesives & Sealants: Imparts improved adhesion to moist surfaces and flexibility in pressure-sensitive and structural adhesives.
• UV-Curable Resins & Inks: Serves as a reactive diluent and modifier to enhance flexibility and adhesion in coatings and printing inks.
• Personal Care Polymers: Employed in the synthesis of film-forming agents and viscosity modifiers for hairsprays, gels, and lotions.
• Chromatography Media: Functional monomer for preparing hydrophilic interaction chromatography (HILIC) stationary phases.
• Dental Materials: Component in dental composites and restorative materials to improve durability and bonding.
• Textile & Leather Finishing: Used in coatings to provide durable, hydrophilic finishes with improved handle and comfort.

Quality Control

Our Poly(2-Hydroxypropyl Methacrylate) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, purity, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as residual monomer content, hydroxyl value, and viscosity are provided and 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 area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties. Keep away from heat and incompatible materials.
