DYNASYLAN SIVO 110

Product Details

Dynasylan® SIVO 110 is composed of organofunctional silanes and functionalized,nanoscale SiO₂ particles. It is an opaque to milky, colorless to slightly yellow, low viscous liquid. Dynasylan® SIVO 110 can be diluted in water and a variety of common organic solvents. Besides reactive silanol groups it also contains organic functionalities based on Si-bonded epoxy groups.

Dynasylan® SIVO 110 is suited as binder component in temperature crosslinking sol-gel coatings and sol-gel - based hybrid coatings. Dynasylan® SIVO 110 coatings boast of:

• high hardness (“Bleistifthärte“ up to 5H, depending on formulation)
• excellent scratch and mar resistance
• superior stability in boiling water (Gt0 upon 2 h treatment in water at 100 °C)
• very good adhesion on various substrates
• very good adhesion towards organic top coats (e.g.epoxies)
• sound flexibility (“Dornbiegeprüfung“ according to DINEN ISO 1519: 2 mm)
• very low thickness of formed layers (recommendation:dry layer of < 2 μm)
• excellent resistance against solvents and other chemicals

Typical Applications

Recommended areas of application:

• corrosion resistant primer systems
• transparent sol-gel top coats which exhibit a temperatureresistance of up to 220 °C
• coatings comprising high hardness, which can beadditionally improved by introduction of up to 20 wt.-% silica sol
• transparent easy-to-clean sol-gel - top coats upon adding Dynasylan® SIVO 112

Dynasylan® SIVO 110 containing formulations can be sprayed, dipped or applied with a doctor blade. It is recommended to orient towards a 0.2 - 2 μm thickness of the dry layer (approx. 4μm of a wet layer equals approx. 1 μm of the respective dry layer). Hence the total quantity to be applied on smooth substrates will amount to approx. 5g / m². Generally for spray application an aqueous dilution should be used (e.g. 20 wt.-% Dynasylan® SIVO 110, 0.06 wt.-% processing agent, 79.94wt.-% water). Surfaces of treated substrates must be clean and free of grease and dust.
