- Product Highlights
- Dynasylan® SIVO 214 contains primary and secondary aminoalkylethoxysilanes.
- The components are bifunctional organic compounds in which the silicon-functional ethoxy groups hydrolyze in the presence of water to give ethanol and the corresponding reactive silanols, which can be bonded to an inorganic substrate; the organophilic amino group can interact with a suitable polymer.
- The composition contains partly six hydrolyzable substituents in one molecule.
- Thus Dynasylan® SIVO 214 is exceptionally suitable to form highly crosslinked networks on and between substrates and in organic matrices.
- Examples of suitable inorganic substrates are glass, glass fibres, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica; also suitable are aluminium hydroxide, kaolin, talc, other silicate fillers, metal oxides and metals.
- Examples of suitable polymers are phenolic resins, furan resins, melamine resins, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC.
- The secondary amino group in Dynasylan® SIVO 214 provides high basicity at somewhat lower reactivity compared to the primary amino groups.
- This is of major advantage in e.g. HFFR cables where the silane is added to the polymer matrix: Homogeneous distribution and bonding/networking of Dynasylan® SIVO 214 to the inorganic filler can commence unless bonding to organic materials (e.g. polymers) will proceed.
- Excellent crosslinking properties make Dynasylan® SIVO 214 a preferred component in the silylation of inorganic filler surfaces and in corrosion-resistant primer systems for metal pretreatment. In foundry resins Dynasylan® SIVO 214 is suited as adhesion promoter between sand and resin.
- This is especially valid for phenolic resins cured by isocyanates. Moreover, Dynasylan® SIVO 214 can be used as a component in aqueous PA- and PU-sizes for glass fibers.

- Processing
- For substrate pretreatments, for example as a primer (as an approximately 0.5-2 percent solution).
- Dynasylan® SIVO 214 can advantageously be employed in organic solvents, such as alcohols, as constituent of aqueous sizes or solutions, as pure substance or added to the polymer as an additive.
- In higher concentrations (1-5 wt.-%) chemical modification can be achieved by reaction with suitable functional monomers or polymers, for example those containing epoxy groups.

Technical Details & Test Data
- Melt Flow Ratio
Melt flow ratio of magnesium hydroxide (MDH) – filled polypropylene compounds.
- Reduced agglomeration is a consequence of improved dispersion of the inorganic in the organic matrix.
- Also the melt flow ratio of the compound is signifi cantly increased.
- The better the choice of silane, the better the compatibilizing effect in the final compound (see diagram).

- Improved Mechanical Properties:
Melt flow ratio of a MDH / PP / PP-MAH compound with different silanesMechanical properties can be improved by chemically coupling the polymer to the filler.
- The chemical bond between the inorganic and the organic part of the compound is crucial to achieve improved mechanical properties.
- The elongation at break of magnesium hydroxide-filled PP based cable compound, for instance, improves significantly, without any adverse effects onto the tensile strength.
