Description

1-(Hydroxymethyl)Undecyl Methacrylate is a specialty methacrylate monomer featuring a long alkyl chain and a pendant hydroxymethyl group, offering unique properties for polymer modification. This bifunctional structure is critical for enhancing hydrophobicity, flexibility, and cross-linking potential in advanced polymer systems. It is primarily needed by formulators and researchers in the coatings, adhesives, and specialty polymer industries seeking to develop high-performance materials with tailored surface characteristics and improved durability.

Application

• Coatings & Paints: Used as a co-monomer to impart hydrophobicity, flexibility, and improved adhesion to metal, plastic, and wood substrates in industrial and protective coatings.
• Adhesives & Sealants: Enhances the tack, peel strength, and low-temperature flexibility of pressure-sensitive adhesives (PSAs) and structural sealants.
• Specialty Polymers: Serves as a building block for synthesizing custom acrylic resins with specific glass transition temperatures (Tg) and mechanical properties.
• Surface Modifiers: Incorporated into polymers to modify surface energy, creating water-repellent or release coatings.
• Cross-linking Agent: The hydroxymethyl group enables participation in cross-linking reactions, increasing the thermal and chemical resistance of the final polymer network.
• UV-Curable Systems: A valuable component in formulations for inks, coatings, and 3D printing resins that cure under ultraviolet light.

Quality Control

Our 1-(Hydroxymethyl)Undecyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identification by FT-IR, to ensure it meets precise specifications for purity and performance. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee consistency and 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). Keep away from heat sources and incompatible materials such as strong oxidizing agents and bases. For long-term storage, consider under an inert atmosphere to maintain optimal quality.
