Description

2-Hydroxypropyl Methacrylate (CAS NO 27813-02-1) is a versatile bifunctional monomer featuring both a polymerizable methacrylate group and a reactive hydroxyl group. This unique structure makes it a critical building block for synthesizing specialty polymers with tailored properties, such as enhanced adhesion, crosslinking capability, and hydrophilicity. It is essential for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop high-performance, functionalized products.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker in formulations for wood, plastic, and metal coatings, offering fast cure speeds and excellent film properties.
• Adhesives & Sealants: Used to manufacture acrylic-based pressure-sensitive adhesives (PSAs) and structural adhesives with improved bonding strength and flexibility.
• Hydrogel & Contact Lens Materials: Imparts hydrophilicity and oxygen permeability in polymers for soft contact lenses, wound dressings, and other biomedical hydrogels.
• Acrylic Resin Modification: Incorporated into acrylic copolymers to introduce pendant hydroxyl groups for subsequent crosslinking with isocyanates or melamines, enhancing durability in automotive and industrial finishes.
• Fiber Optic Coatings: Serves as a primary monomer in coatings that protect optical fibers, providing necessary flexibility, adhesion, and environmental resistance.
• Dental Composites & Restoratives: A component in dental resin systems, contributing to mechanical strength and biocompatibility.
