Dynasylan® TRIAMO

1 of 42 products in this brand
Dynasylan® TRIAMO is an organofunctional silane, possesses three reactive amino groups and a hydrolyzable trimethoxysilyl group. Its dual reactivity enables chemical binding to both inorganic materials (e.g., glass, metals, fillers) and organic polymers (e.g., thermosets, thermoplastics, elastomers). This versatile compound acts as an adhesion promoter and surface modifier. Presenting as a clear, light to dark yellow liquid with a subtle amine-like odor, Dynasylan® TRIAMO is soluble in alcohols, ketones, esters, and aliphatic and aromatic hydrocarbon solvents.

Chemical Family: Amines

Functions: Adhesion Promoter, Coupling Agent, Surface Modifier

Features & Benefits

Industrial Additives Features
  • In the presence of water, the methoxy (Si-OCH3 ) groups of Dynasylan® TRIAMO hydrolyze to form reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates.
  • The amine groups of Dynasylan® TRIAMO can react with a suitable polymer. Dynasylan® TRIAMO may be used with PVC and silicones.
