Dynasylan® SIVO 214 is a blend of primary and secondary aminofunctional silanes.
The blend contains up to 80 wt% of 3-aminopropyltriethoxysilane and up to 20% 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 214 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 214 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 214 may be used as a constituent of aqueous sizes, neat, or added to a resin or polymer as a modifier.
Examples are:
Dynasylan® SIVO 214 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 214 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 214 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.
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.
