DESCRIPTION
KeySil WR 680-P Silicone Hydrophobic Powder was developed to offer the performance of a liquid silicon-based hydrophobic material in a dry delivery systems. KeySil WR 680-P Silicone Hydrophobic Powder is a formulation containing a finely dispersed silicon-based active. The powdered composition provides good storage stability and release of the active ingredient upon addition of water. This product can find uses in many application areas where the protection of the substrate from liquid water ingress is a critical issue.
KeySil WR 680-P Silicone Hydrophobic Powder provides excellent dispersibility into water.
As with other silane-based products, bulk hydrophobic property of mortar modified with KeySil WR 680-P Silicone Hydrophobic Powder is expected to be resistant to UV radiation.
HOW TO USE
KeySil WR 680-P Silicone Hydrophobic Powder is a dry powder. This product is intended to be added to the dry ingredients of the cement based composition.
Determination of optimum addition levels should be evaluated in the laboratory.
Most applications will typically require between 0.1 and 0.5 weight % KeySil WR 680-P Silicone Hydrophobic Powder in the dry mix.
The water level of the final formulation should be optimized to the desired consistency.
Cement-based mixtures formulated using KeySil WR 680-P Silicone Hydrophobic Powderr can be mixed and applied using standard industry equipment. Heating should be avoided during or after mixing KeySil WR 680-P Silicone Hydrophobic Powder in dry mix formulations.
