Dynasylan® DAMO-T

Dynasylan® DAMO­T is a bifunctional organosilane possessing two reactive amino groups and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® DAMO­T to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter and surface modifier. Dynasylan® DAMO­T is a yellow liquid with an amine­like odor. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.

Processing Information

For substrate pretreatments (e.g. as a primer) Dynasylan® DAMO­T may be used as an approximately 0.5­2 wt.­% solution in an organic solvent such as alcohol, as a constituent of aqueous sizes or solutions, neat, or added to the polymer as an additive (at higher concentration: 1­10 wt.­%).

Product Applications
  • Dynasylan® DAMO-T is an important ingredient in many applications. Examples include:
  1. Glass fiber/glass fabric composites: as size constituent or finish
  2. Glass and metal primers
  3. Sealants and adhesives: as primer or additive
  4. Mineral-filled polymers (composites): for pre-treatment of fillers and pigments or as additive
  5. Paints and coatings: as additive and primer for improving adhesion to the substrate
  • The most important effects of Dynasylan® DAMO-T:
  1. Improvement in product properties, such as:
  2. Flexural strength, tensile strength, impact strength, and modulus of elasticity
  • Moisture and corrosion resistance
  • Improvement in processing properties, such as:
  • Adhesion

Product Reactivity
  • In the presence of water the methoxy groups of Dynasylan® DAMO­T hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates. The organophilic diamino group of Dynasylan® DAMO­T can react with a suitable polymer.
  • The hydrolysis of Dynasylan® DAMO­T takes place autocatalytically. The pH value of the hydrolysate is about 10­ 11. For a longer stability of the hydrolysate a pH of 4 is recommended. Examples of suitable inorganic substrates are glass or glass fibers. Dynasylan® DAMO­T may be used with such polymers as phenolic, furan resins, PA, PBT, PC, EVA, modified PP, PVAC, PVC, acrylates and silicones.
  • Dynasylan® DAMO­T can undergo reactions with ketone or ester solvents. The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates.
