Description

Dotriacontyl Methacrylate is a high molecular weight, long-chain alkyl methacrylate monomer. This specialty chemical is valued for its ability to impart exceptional hydrophobicity, flexibility, and low surface energy to polymer chains. It is primarily sought after by industrial formulators and polymer chemists in the coatings, adhesives, and advanced materials sectors to create high-performance, tailored copolymers with specific surface properties.

Application

• Hydrophobic Coatings: A key monomer for formulating water-repellent and anti-fouling coatings for marine, automotive, and architectural applications.
• Internal & External Plasticizers: Used to enhance the flexibility and low-temperature performance of acrylic and vinyl polymers without migration issues.
• Pressure-Sensitive Adhesives (PSAs): Modifies tack and peel strength while improving water resistance in adhesive tapes and labels.
• Surface Modifiers & Additives: Incorporated into polymers to reduce surface friction and improve lubricity in films and molded parts.
• Oil & Gas Industry Additives: Utilized in the synthesis of flow improvers and pour point depressants for crude oil and fuels.
• Specialty Resins: Serves as a comonomer in the production of high-value resins for inks, toners, and photopolymers.

Quality Control

Our Dotriacontyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identity confirmation (IR), and analysis of key impurities like residual monomer and inhibitors. A Certificate of Analysis (COA) documenting purity, appearance, and specific gravity is provided with each shipment to ensure it meets your precise formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Keep away from heat, sparks, and open flame. For long-term storage, refrigeration may be recommended; please consult the specific product data sheet.
