WACKER® Silicate MKS is an ethyl silicate binder suitable for the formulation of one-pack ethyl silicate zinc-rich primers. These primers are excellent anti-corrosive coatings.



Properties

WACKER® Silicate MKS offers these advantages:

  • ready-to-use binder, no further chemical hydrolysis required
  • developed for the formulation of storage-stable one-pack zinc rich primers
  • Product offers outstanding anti-properties, added zinc dust can be easily stirred up
  • moisture-curing

Store in a dry and cool place.

Protect against moisture.

WACKER® Silicate MKS is a binder with outstanding antisetting 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 additives and zinc dust in that order to WACKER® Silicate MKS 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.
It is also important that the added components do not introduce uncontrolled amounts of water into the system as this would adversely affect the processing time / shelf life of the formulation.
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 MKS 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

Packaging

  • 25 kg steel can
  • 180 kg steel drum

Storage

WACKER® Silicate MKS 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.
