Description

2-Hydroxypropyl Methacrylate (CAS NO 923-26-2) 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 advanced polymers with tailored properties, such as improved adhesion, crosslinking capability, and enhanced hydrophilicity. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to develop high-performance, functional materials.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, providing fast curing, high gloss, and excellent chemical resistance.
• Adhesives & Sealants: Used to manufacture pressure-sensitive adhesives (PSAs), structural adhesives, and sealants, improving flexibility and bond strength.
• Hydrogel Production: Serves as a co-monomer for synthesizing soft contact lenses, wound dressings, and other biomedical hydrogels due to its hydrophilic nature.
• Acrylic Resin Modification: Incorporated into acrylic copolymers to introduce crosslinking sites, enhancing durability, solvent resistance, and hardness in automotive and industrial finishes.
• Reactive Diluent: Functions as a low-viscosity, reactive diluent in unsaturated polyester and radiation-curable systems, reducing VOC emissions.
• Textile & Leather Finishes: Used in polymers for fabric coatings and leather finishes to impart water repellency, softness, and abrasion resistance.
