Water Repellents
Sitren® P & Tegosivin®
Product description
The water repellents Sitren® P and Tegosivin® from EVONIK are silane and/or siloxane based additives for a wide range of construction products.
Water (in form of ascending moisture or splash water) can have a very negative effect on mechanical properties, appearance and durability of construction products. A good hydrophobicity reduces water uptake and water transport in the end product. In addition, hydrophobic surfaces show a much lower dirt uptake by the so-called beading effect.
Our program includes powdered products for dry mortars (repair mortars, tile adhesives, grouts, levelling compounds or renders) as well as liquid products for concrete admixtures.
