ELOTEX® SRT100 is an encapsulated fluoroalkyl silane in powder form that provides outstanding water and oil repellent properties for easy-to-clean surfaces of cementitious mortars. The active ingredient of ELOTEX® SRT100 is released when the mortar is mixed with water, and it subsequently binds covalently to the inorganic mortar matrix. Therefore, it offers long term durability, an outstanding pearl effect, and excellent stain resistance for cement based mortars. ELOTEX® SRT100 is fully efficient in alkaline medium at pH > 10. It provides excellent protection against water and oil penetration even at very low dosage. ELOTEX® SRT100 provides mortars with excellent wetting and mixing properties and is easy to dose with low dust formation. Furthermore, it has a long term shelf-life.
