Dynasylan® SIVO 110

Dynasylan® SIVO 110 is a multifunctional, almost VOC-free, water-borne sol-gel system.

Typical Applications

Dynasylan® SIVO 110 is suited as binder component in temperature crosslinking sol-gel coatings and sol-gel-based hybrid coatings. Dynasylan® SIVO 110 coatings are performing with:
- 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 DIN EN ISO 1519: 2 mm)
- very low thickness of formed layers (recommendation: dry layer of < 2 µm)
- excellent resistance against solvents and other chemicals
Recommended areas of application:
1. corrosion resistant primer systems
2. transparent sol-gel top coats which exhibit a temperature resistance of up to 220 °C
3. coatings comprising high hardness, which can be additionally improved by introduction of up to 20 wt.-% silica sol
4. 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. 4 µm 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, 79.94 wt.-% water). Surfaces of treated substrates must be clean and free of grease and dust.

Benefits at a glance

Dynasylan® SIVO 110 is a water-borne sol-gel system which does not contain organic solvents. It does not release alcohols upon hydrolysis contrary to standard functional alkoxysilanes. Dynasylan® SIVO 110 contains a high concentration of active silanol functions. Consequently it can chemically bond to surfaces of suited substrates and achieves a high degree of crosslinking by formation of 2- and 3-dimensional siloxane networks. During curing functionalized SiO2 nanoparticles align into a densely packed structure and are covalently incorporated into the siloxane network. This causes the explanation why exceptional hardness and scratch resistance of Dynasylan® SIVO 110. Additionally a high degree of flexibility is obtained at a considerably low thickness fo the formed layers. Suited substrates: steel, stainless steel, Zn-galvanized steel, aluminum, glass. Complete crosslinking (including reaction of silanol groups) will be reached at temperatures between a minimum of 180 °C and, ideally, 200-220 °C.
