ELOTEX® SEAL712 is an encapsulated silane in powder form that provides excellent water-repellent properties on the surface and in mass of gypsum based mortars. The active ingredient of ELOTEX® SEAL712 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® SEAL712 needs to be activated in an alkaline medium and is fully efficient at pH > 10. ELOTEX® SEAL712 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. It reduces the need for priming while retaining good paintability and coatability properties.
