Encapsulated Silane

ELOTEX® SEAL81 is an encapsulated silane in powder form that provides excellent water-repellent properties on the surface and in mass of cementitious mortars. The active ingredient of ELOTEX® SEAL81 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 and an excellent pearl effect. ELOTEX® SEAL81 is fully efficient in alkaline medium at pH > 10. It provides significant reduction in water uptake. ELOTEX® SEAL81 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.
