Silsan® WDF

Silsan® WDF by Graf is a modified polysiloxane. It acts as a water repellent agent. It is micro-molecular emulsion which provides excellent water repellent properties. It increases water repellent effect of the coating system and reduces absorption of water to a minimum without any negative effect on the water-vapor permeability. It is firmly embedded into the matrix structure of the coating and provides long-lasting and reliable water intrusion protection which does not lose its effectiveness even under extreme weathering conditions. Silsan® WDF is used with pure emulsion based coatings as well as in silicone resin and silicate based coatings. Suitable for aqueous coatings, fillers, masonry paints and plasters. It has shelf life of 12 months.
