Silsan® silicon water repellent additives: reduce water absorption of masonry coatings.

Silicone water repellent additives, based on functionally modified polysiloxanes, help to keep facades dry. The active ingredient which provides the water repellency is able to cover the sides of pores and capillaries completely, making them water repellent without sealing them. Thereby, the breathability of the material remains intact and the natural moisture level of the building structure is kept well balanced.

Basic types:

Silsan® CC-55: high water proofing effect; marginal water beading effect; for emulsion based paints and plasters and emulsion-silicate paints and plasters.

Silsan® 1350: very high water proofing effect; moderate water beading effect; for emulsion based paints and plasters and effect booster in silicone resin paints and plasters

Silsan® WDF: 100% active concentration; the stronger Lotus-effect; especially for filler pastes and reinforcing filler pastes.
