WACKER® Silicate S100
WACKER® Silicate S100 is a ready-to-use ethyl silicate binder with a flash point >21°C.
Typical use is the formulation of single-pack ethyl silicate zinc rich primers (anti-corrosive coating).
WACKER® Silicate S100 offers these advantages:
- ready-to-use binder, no chemical hydrolysis required
- developed for the formulation of storage-stable single-pack zinc rich primers
- Product offers outstanding anti-properties, added zinc dust can be easily stirred up
Store in a dry and cool place.
Protect against moisture.
WACKER® Silicate S100 is suitable for the formulation of ready-to-use one-pack systems with a flash point >21°C.
WACKER® Silicate S100 is a binder system with out-standing anti-settling properties. Paints formulated with it are easy to stir up even if they have been stored for a long time. Once a coating has been applied, it will cure under the influence of atmospheric moisture and can be easily overpainted with any standard paint.
To prepare a ready-to-use zinc-rich paint, add the anti-settling agents and zinc dust in that order to WACKER® Silicate S100, dispersing them with a high-speed mixer. Solvents can be used to adjust the desired SiO2 content or the desired viscosity of the formulation. Add the solvents while the stirrer is at low speed. The temperature of the premix should not be higher than 40°C.
Once the zinc-rich paint has been applied, it must be fully exposed to atmospheric moisture (approx. 50% r. h.). The binder will then hydrolyze and cure very rapidly to produce a hard coating.
Zinc-rich paints based on WACKER® Silicate S100 may be used as primers or on their own. They protect steel from corrosion:
- in aggressive industrial and coastal atmospheres
- at high temperatures (up to 420°C)
- in the presence of chemicals
- 180 kg Fass
- 900 kg IBC
WACKER® Silicate S100 must be stored in the tightly closed original container under exclusion of moisture.
The "Best use before end" date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
