Powder additives for mineral building materials

Application:

Silicone water repellent additive in powder form for cement-based mineral construction material mixes, e.g. premixed plasters, mortars, grouts and powder paints

Properties:

For cement-based building materials Water soluble Excellent water repellency Does not influence permeability to water vapour High early water resistance Creates a beading effect Low soiling tendency

Chemical description:

Blend of liquid hydrocarbons and emulsifiers on an inorganic carrier

Active substance:

Approx. 20%

Solvent:

-

Appearance:

Yellowish powder

Application:

Improves in gypsum- and cement based dry-mix systems key properties as workability and productivity of the wet mortar, settling properties and adhesion on critical surfaces

Properties:

Excellent water binding and water retention ability Rheological control of the wet mortar No adhesion of the wet mortar on the trowels, therefore clean tools excellent suspending and stabilizing of the mineral components Excellent alkaline resistance Long open time High stability of the wet mortar on vertical surfaces Crack-free settling

Additional level & application:

Required quantity: machine and hand applied plasters based on gypsum or cement: 0.1 – 0.3 % putties based on gypsum or cement: 0.3 – 0.8 % (calculated on the dry weight of the masses)
