TEGOSIVIN HE 861 is a solvent-free emulsion based on organo-silanes providing efflorescence prevention and protection against de-icing salts. It reduces heat conductivity for improved thermal insulation with a non-tacky finish and stain release effect. With an active content of approx. 60% and density of 0.92 g/cm3, TEGOSIVIN HE 861 is solvent-free and diluted with water for production of ready-to-use formulations. It exhibits excellent beading properties for mineral substrates, providing durable protection from water-induced damage. TEGOSIVIN HE 861 allows for high impregnation depth even with repeated application, protecting structures effectively in driving rain conditions.
