Dynasylan® SIVO 210

Dynasylan® SIVO 210 is a blend of primary and secondary aminofunctional silanes.
The blend contains up to 50 wt% of 3-aminopropyltriethoxysilane and up to 50% of secondary amines like Bis-(triethoxysilylpropyl)amine. The blend posses silanes having reactive primary and secondray amino groups as well as hydrolyzable ethoxysilyl group. The dual nature of this reactivity allows Dynasylan® SIVO 210 to bind chemically to both inorganic materials (e.g. glass, metals and fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers) thus functioning as an adhesion promoter, a surface modifier and a reactive reagent.
Dynasylan® SIVO 210 is a yellowish liquid with an amine-like odor. It is soluble in alcohols as well as aliphatic or aromatic hydrocarbons.

Typical Applications

Dynasylan® SIVO 210 may be used as a constituent of aqueous sizes, neat, or added to a resin or polymer as a modifier.
Examples are:
  • glass fiber/glass fabric composites: as a finish or size constituent
  • mineral fiber insulating materials and abrasives: as an additive to phenolic resin binders
  • foundry resins: as an additive to phenolic, furanic and melaminic resins
  • sealants and adhesives: as a primer or additive and for chemical modification
  • mineral-filled polymers or HFFR cables: for pretreatment of fillers and pigments
  • paints and coatings: as an additive and primer for improving adhesion to the substrate.
  • as a primer for glass and metal surfaces.

Dynasylan® SIVO 210 may react with a variety of inorganic substrates and modify their surfaces. Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, cristobalite, wollastonite, mica as well as aluminum trihydrate, magnesium dihydrate, kaolin, talc, other silicate fillers, metal oxides and metals.
Dynasylan® SIVO 210 may react with a variety of organic resins and polymers and form silane-functionalized materials. Examples of suitable organic resins and polymers are epoxy, phenolic, furanic and melaminic resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, PS, polyester, acrylates and silicones.
Dynasylan® SIVO 210 can undergo reactions with ketone or ester solvents. Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates.
Addition reactions with suitable monomeric or polymeric compounds (e.g. isocyanates, epoxides, etc.) are established and state of the art.

Benefits at a glance

Dynasylan® SIVO 210 is exceptionally suitable to form highly crosslinked networks on and between organic substrates and inorganic matrices. Therefore Dynasylan® SIVO 210 is a preferred component in the modification of inorganic filler surfaces and in corrosion-resistant primer systems for metal pretreatment.
Dynasylan® SIVO 210 contains primary and secondary aminoalkyl(triethoxysilanes). The components are bifunctional organic compounds in which the silicon-functional ethoxygroups 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.
Examples of suitable inorganic substrates are glass, 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, furane resins, melamine resins, PA, PBT, PC, EVA, modified PP, PVB, PVAC or PVC.
The secondary amino group in Dynasylan® SIVO 210 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 210 to the inorganic filler can commence unless bonding to organic materials (e.g. polymers) will proceed.
