- Reactivity
- In the presence of water, the methoxy groups of Dynasylan® MTMO hydrolyze and form reactive silanol groups which can bond to a variety of inorganic substrates.
- The organophilic mercapto end of Dynasylan® MTMO can react with a suitable polymer.
- Hydrolysis of Dynasylan® MTMO is catalyzed by acids.
- Examples of suitable inorganic substrates are glass, glass fibers, silicia, quartz, sand, cristobalite, mica kaolin, talc, other silicate fillers and metals.
- Dynasylan® MTMO may be used with such polymers as polyurethanes, polysulfides, sulfur-cured and metal oxide-cured elastomers.
- Product modifications are possible by using Dynasylan® MTMO in addition or grafting reactions with suitable monomers or polymers (e.g. isocyanates, PVC etc.). An Si-O-Si crosslinking can take place via the silicon functional groups of the silane.
Applications & Uses
- Applications
- Coating Type
- Application Characteristics
Dynasylan® MTMO is used in applications such as:
- glass composites: as a finish or a size ingredient
- glass and metal primer
- sealants and adhesives: as a primer, additive, or for chemical modification of the polymer
- mineral filled polymers: for pretreatment of fillers and pigments or as an additive
- crosslinking of polymers
Important product effects that can be achieved through the use of Dynasylan® MTMO include:
- Compression set
- Improved mechanical properties, e.g. flexural strength, tensile strength, impact strength and modulus of elasticity, tear strength
- Improved moisture and corrosion resistance
- Improved electrical properties, e.g. dielectric constant, volume resistivity
- Increased thermal resistivity
Dynasylan® MTMO can also improve such processing properties as:
- cure time
- adhesion
- filler dispersion
- rheological behavior: (e.g. viscosity reduction)
- higher filler loading
- Processing
- Dynasylan® MTMO can be used as a primer (i.e. a ca. 0.5-10 wt.%. solution in an organic solvent such as alcohol), as an ingredient in a solution, or neat.
- A chemical modification can be achieved by reaction of Dynasylan® MTMO with suitable functional monomers or polymers.
