The products of OBTEGO AG primarily come within the performance feature "Protection against the ingress of substances", whereby the silicate-containing products also improve the mechanical properties (e.g. scratch resistance). Since OBTEGO products aremainly penetrating products, that leave no or only a minimal filmon the surface, they usually cannot scratch or peel off, like film-forming impregnators / sealers or coatings. Treatment of the concrete to create a water-repellent surface. Pores and capillaries are only lined out, but not filled. No film forming after application on the concrete surface. The appearance of the surface changes little or not at all. NOTE: Active agents can be silanes and siloxanes. Treatment of the concrete to reduce the surface porosity and to strengthen the surface. The pores and capillaries are partially or completely filled. NOTE 1: This treatment usually results in an uneven, thin film on the concrete surface. NOTE 2: Binders can e.g. organic polymers. Treatment to create a closed protective layer on the concrete surface. NOTE 1: The thickness is usually 0.1 mm to 5.0 mm. Special appl ications may require a thickness greater than 5mm. NOTE 2: Binders can e.g. organic polymers (with cement as an addi t i ve) or wi th polymer dispersion modified hydraulic cement.
