Description

Methanamine, n-Methyl-, Reaction Products With Hydrolyzed Epoxidized Polybutadiene is a specialized polymeric amine derivative, synthesized from the reaction of methylamine with hydrolyzed epoxidized polybutadiene. This product is valued for its unique combination of amine functionality and a flexible, hydrophobic polymer backbone, making it an effective reactive intermediate and property modifier. It is primarily utilized in the formulation of advanced adhesives, coatings, and elastomers where enhanced chemical resistance, adhesion, and cross-linking density are required. The CAS number for this compound is 68441-50-9.

Application

• Adhesive Formulation: Acts as a curing agent and adhesion promoter in high-performance epoxy and polyurethane adhesives for automotive and aerospace composites.
• Protective Coatings: Serves as a cross-linking agent and corrosion inhibitor in industrial and marine coatings, improving durability and chemical resistance.
• Elastomer Modification: Used as a reactive plasticizer or compatibilizer in nitrile, polybutadiene, and other specialty rubbers to enhance oil and solvent resistance.
• Composite Materials: Functions as a coupling agent in fiber-reinforced plastics (FRP) to improve the interfacial bond between the matrix and reinforcement.
• Sealants and Encapsulants: Imparts flexibility and improved adhesion in polysulfide and polyurethane-based sealants for construction and electronics.
• Printing Inks: Utilized as a resin modifier in solvent-based inks to improve pigment wetting, gloss, and substrate adhesion.
