ELOTEX® SEAL200 is an encapsulated silane in powder form that provides outstanding water-repellent properties on the surface and in mass of cementitious mortars. The active ingredient of ELOTEX® SEAL200 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 ® SEAL200 is fully efficient in alkaline medium at pH > 10. It provides significant reduction in water uptake even at very low dosage. ELOTEX® SEAL200 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.
