Description

12-Hydroxydodecyl Methacrylate is a long-chain hydroxyl-functional methacrylate monomer, also known as 12-Hydroxylauryl Methacrylate. This bifunctional monomer is highly valued for its ability to introduce both polymerizable methacrylate groups and pendant hydroxyl groups into polymer chains, enabling crosslinking and enhancing adhesion properties. It is essential for formulators and polymer chemists in the coatings, adhesives, and advanced materials sectors seeking to improve product performance, durability, and surface interaction.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker in formulations requiring fast cure speeds, high gloss, and excellent adhesion to various substrates, including plastics and metals.
• Adhesives & Sealants: Used to synthesize acrylic polyols for polyurethane adhesives, enhancing flexibility, toughness, and bond strength, particularly in structural and pressure-sensitive applications.
• Hydrophilic Modification of Polymers: Imparts hydrophilicity and improves biocompatibility in polymers for contact lenses, hydrogel medical devices, and controlled-release drug delivery systems.
• Automotive & Industrial Coatings: Incorporated into acrylic resin backbones to improve weatherability, chemical resistance, and scratch resistance in topcoat formulations.
• Fiber Optic Coatings: Serves as a primary coating material component, providing a protective, flexible layer with low modulus and high adhesion to glass fibers.
• 3D Printing Resins (SLA/DLP): A functional monomer in photopolymer resins, contributing to part toughness, resolution, and post-curing properties.
• Surface Modifiers & Additives: Used to graft polymers onto surfaces or nanoparticles, creating stable dispersions and functionalized materials for composites and electronics.

Quality Control

Our 12-Hydroxydodecyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC, hydroxyl value determination, and color/water content analysis, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with every shipment 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 temperatures between 15-25°C (59-77°F). Keep away from heat sources and incompatible materials such as strong oxidizing agents and bases. For long-term storage, consider under an inert atmosphere (nitrogen) to maintain optimal quality.
