Dynasylan® DAMO

Dynasylan® DAMO is a diamino­functional silane which acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers) and as a surface modifier. Dynasylan® DAMO is a colorless to slightly yellowish liquid with an amine­like odour which is soluble in alcohols and aliphatic as well as aromatic hydrocarbons.

Product Applications
  • Dynasylan® DAMO 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:
  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
Processing Information

For substrate pretreatments, for example, as a primer (as an approximately 0.5-10 percent solution), Dynasylan® DAMO can advantageously be employed in organic solvents, such as alcohols and constituent of aqueous sizes or solutions. It may also be used as a pure substance or added to the polymer as an additive.

Product Reactivity
  • Dynasylan® DAMO is a bifunctional organic compound in which the silicon-functional methoxy-groups hydrolyze in the presence of water to form reactive silanols, which can be bonded to an inorganic substrate; the organophilic amino group can interact with a suitable polymer.
  • The hydrolysis of Dynasylan® DAMO takes place autocatalytically. The pH of the hydrolysate is about 10-11. For longer stability of the hydrolysate, a pH of 4 is recommended.
  • Examples of particularly suitable inorganic substrates are glass or glass fibers. Suitable polymers are PA, PBT, PC, EVA, modified PP, PVAC, PVC, acrylates, and silicones.
  • Dynasylan® DAMO can undergo reactions with ketones or esters as solvents. The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates resp. carbamates. Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (for example, isocyanates, epoxides, etc.).
