Evonik Dynasylan DAMO-M Beta-aminoethyl-gamma-aminopropyltrimethoxysilane (methoxy-modified)

Evonik Dynasylan DAMO-M is a methoxy-modified beta-aminoethyl-gamma-aminopropyltrimethoxysilane coupling agent from the Dynasylan® series. It enhances adhesion between organic polymers and inorganic substrates like glass, metals, or minerals. Its dual amine functionality and hydrolyzable methoxy groups enable superior interfacial bonding, moisture resistance, and dispersion stability in coatings, adhesives, and composites.

Features Of Evonik Dynasylan DAMO-M Beta-aminoethyl-gamma-aminopropyltrimethoxysilane (methoxy-modified)

  1. Bifunctional silane with two distinct primary amine groups—beta-aminoethyl and gamma-aminopropyl—enabling dual reactivity toward epoxy, carboxyl, and carbonyl functionalities.

  2. Methoxy-modified structure offers improved hydrolytic stability versus ethoxy analogues, extending shelf life and simplifying handling in moisture-sensitive formulations.

  3. Enhanced compatibility with polar polymers and inorganic fillers due to balanced hydrophilicity and organophilicity from the asymmetric diamino architecture.

  4. Acts as an efficient coupling agent for silica-reinforced elastomers, significantly improving filler dispersion and interfacial adhesion.

  5. Enables covalent immobilization of biomolecules or functional dyes on glass, silica, or metal oxide surfaces in bioconjugation and sensor applications.

Typical Applications Of Evonik Dynasylan DAMO-M Beta-aminoethyl-gamma-aminopropyltrimethoxysilane (methoxy-modified)

  1. Adhesion promoters in high-performance automotive sealants and structural adhesives bonding metals, composites, and coated substrates.

  2. Surface modifier for silica, glass fibers, and nanocellulose in thermoset composites (e.g., epoxy, phenolic) to enhance mechanical strength and moisture resistance.

  3. Functionalization agent for chromatographic stationary phases and diagnostic assay substrates requiring oriented amine presentation.

  4. Co-monomer in hybrid sol-gel coatings for corrosion protection of aluminum and steel substrates.

  5. Dispersion aid and compatibilizer in waterborne polyurethane and acrylic dispersions for industrial coatings and adhesives.
