potassium methylsiliconate cas 31795-24-1

1.Low-fired clay products immediately after they have been made: e. g. roof tiles, facing bricks, floor tiles, flower pots.
2.Aerated concrete.
3.Gypsum and gypsum-based fiber boards.
4.Light fillers, such as perlite, vermiculite and aerated concrete granules.
5.Insulating materials.
6.As a surface treatment Silway 714 is diluted to a concentration of 3 percent solids or less prior to application.
7.Do not use concentrations higher than 3 percent solids unless prior testing indicates a necessity. The use of higher concentrations than required may result in the formation of a white residue on the surface. Users should test the concentration to be applied on the substrate prior to use.3. After application of the silicone solution, allow the treated surface to dry for at least 24 hours to develop maximum water repellency. This interval may be shortened somewhat by force-drying at temperatures up to 175°C. While this removes the water quickly, time must be allowed for the curing reaction between Silway 714 and the surface being treated. Carbon dioxide streams do not appear to reduce the cure time appreciably.
