Description

Dodecyl Methacrylate is a high-purity, long-chain alkyl methacrylate monomer essential for creating polymers with specific hydrophobic and low-temperature flexibility properties. Its primary value lies in its ability to impart internal plasticization, water repellency, and enhanced solubility to acrylic copolymers. This makes it a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to improve product performance and durability.

Application

• Coatings & Paints: Used as a co-monomer to formulate solvent-based and radiation-curable coatings, providing excellent water resistance, flexibility, and adhesion to various substrates.
• Adhesives & Sealants: Imparts low-temperature flexibility and improved tack to pressure-sensitive adhesives (PSAs) and structural adhesives.
• Acrylic Resins & Plastics: Serves as a modifying monomer to produce impact-resistant acrylic sheets, molding compounds, and resins with enhanced weatherability.
• Textile & Leather Finishes: Employed in polymers for fabric coatings and leather finishes to provide durable, hydrophobic, and soft-hand properties.
• Lubricant & Fuel Additives: Acts as a precursor for viscosity index improvers and pour-point depressants in lubricating oils and industrial fluids.
• Personal Care Polymers: Used in the synthesis of film-forming agents and fixative polymers for hairsprays, nail polishes, and other cosmetic products.
