Description

3-(Dimethylamino)Propyl Methacrylate is a versatile, tertiary amine-functional methacrylate monomer that serves as a critical building block for specialty polymers. Its unique structure, featuring both a polymerizable methacrylate group and a reactive dimethylamino group, enables the introduction of cationic charge, adhesion promotion, and crosslinking sites into polymer chains. This compound is essential for formulators and polymer chemists in the coatings, adhesives, and personal care industries seeking to enhance product performance through tailored functionality.

Application

• Cationic Polymer Synthesis: Key monomer for producing polymers with permanent positive charge, used in flocculants, retention aids for papermaking, and conductive materials.
• UV-Curable Coatings & Inks: Imparts adhesion to difficult substrates and improves pigment wetting and flow properties in radiation-curable systems.
• Acrylic Resin Modification: Incorporated into acrylic copolymers to introduce tertiary amine functionality for improved water solubility, corrosion resistance, or as a catalyst anchor site.
• Personal Care Polymers: Used in the synthesis of cationic conditioning polymers for hair care and skincare products, providing antistatic and softening effects.
• Adhesive & Sealant Formulations: Enhances adhesion to polar surfaces and can act as a reactive diluent or crosslinking agent in structural and pressure-sensitive adhesives.
• Quaternary Ammonium Compound Precursor: The tertiary amine group can be readily quaternized to produce monomers or polymers with enhanced biocidal or antistatic properties.

Quality Control

Our 3-(Dimethylamino)Propyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and identity confirmation, to ensure it meets precise specifications for polymerization-grade monomers. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature and potential for polymerization, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to use inhibitors as supplied.
