Features & Benefits
- CASE Ingredients Features
- Materials Features
- Reactivity
- In the presence of water the methoxy groups of Dynasylan® DAMO-T hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates.
- The organophilic diamino group of Dynasylan® DAMO-T can react with a suitable polymer.
- The hydrolysis of Dynasylan® DAMO-T 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® DAMO-T may be used with such polymers as phenolic, furan resins, PA, PBT, PC, EVA, modified PP, PVAC, PVC, acrylates and silicones.
- Dynasylan® DAMO-T 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.

- Application Characteristics
Dynasylan® DAMO-T is an important additive in applications such as:
- glass fiber/glass fabric composites: as a finish or size constituent
- glass and metal primers
- foundry resins: as an additive to various types of foundry resins
- sealants and adhesives: as a primer or additive
- mineral-filled polymers (composites): for pretreatment of fillers and pigments or as an additive
- paints and coatings: as an additive and/or primer for improving adhesion to the substrate
The most important effects which can be achieved through the use of Dynasylan® DAMO-T are:
- Improved product properties, such as
- flexural strength, tensile strength, impact strength and modulus of elasticity
- moisture and corrosion resistance
- Improved in processing properties, such as
- adhesion
- Processing
For substrate pretreatments (e.g. as a primer) Dynasylan® DAMO-T may be used as an approximately 0.5-2 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: 1-10 wt.-%).
