Description

Hydroxydodecyl Methacrylate is a specialty methacrylate monomer featuring a long alkyl chain and a reactive hydroxyl group. This bifunctional structure is critical for imparting unique properties like hydrophobicity, flexibility, and crosslinking capability to polymer formulations. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance. This product is supplied under the identifier CAS NO 76736-66-8.

Application

• UV-Curable Coatings & Inks: Serves as a key reactive diluent and crosslinker, improving adhesion, flexibility, and chemical resistance on plastics and metals.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify tack, peel strength, and provide internal crosslinking for enhanced cohesive strength.
• Acrylic Resin Modification: Used as a comonomer to introduce long-chain hydrophobicity and pendant hydroxyl groups for subsequent reactions in industrial and automotive coatings.
• Fiber Optic Coatings: Imparts necessary mechanical protection and low moisture absorption in primary and secondary coatings for optical fibers.
• Dental & Biomedical Materials: Employed in the synthesis of biocompatible polymers for restorative materials and drug delivery systems due to its polymerizable groups.
• Lithographic Printing Plates: Acts as a functional monomer in photopolymerizable compositions to create durable, high-resolution image layers.
