RC 224 HYDROFUGE BASED ON ALKYL OLIGOMERE POLY SILOXANE 10% KIK REPORT NR.2004.08263 Art. 21003 2.HYDROFUGE Chemical products for construction and renovations Description RC 224 is a colorless water-repellent high quality product for the treatment of mineral building materials. RC 224 is UV and alkali resistant, and this without changing the aspect of the surface and the preservation of the vapor permeability. After the application of the RC 224, the active product undergoes a chemical conversion: it is a polysiloxane and provides a permanent water-repellent and good pearling effect. RC 224 is a ready to use dilution of a high quality and low molecular siloxane (10% active agents) dissolved in a slow evaporating hydrocarbon fraction with a high penetration capability. Traits For making bricks, concrete blocks, aerated concrete and all porous rocks (white limestone) who are constantly undergoing the adverse influence of rain, water repellent. • Reduction of water absorption and indoor humidity. • Protect against contamination of cleaned facades. • Prevention of salt efflorescence and frost damage. • Reduce moss. • Perfect vapor permeable. • Protect against acid rain. Surface In the application of RC 224, the surface should be as mentioned in § 5.4 of TV 224 of the CSTC clean, sound and dry We remind you that before treating old soiled surfaces cleaning is recommended. (See cleaning techniques in TV 197 of the CSTC and our chapter regarding cleaning agents). After cleaning, please rinse until it is completely dust free the subsurface. Joints, cracks or cavities in the stone should be repaired first .One should, however wait 2 days before starting with the impregnation of fresh jointing. Pulverized material should first be treated a stone strengthener from our range (RC stone strengthener) in order to rebuild the mineral structure. After the treatment with our stone strengthener one should wait 24 hours before one applies RC 224. Application The treatment is preferably carried by the irrigation of the substrate under low pressure, so that no misting or atomizing of the product takes place. The treatment takes place from bottom to top with a horizontal reciprocating motion, so that a flush of approximately 20 cm is obtained. Two treatments should be carried out. Wet-on-wet. The use of a Backpack Sprayer is recommended, or an electric pump as long as it ensures that the product flows at a constant pressure across the surface. Consumption Is highly dependent on the porosity of the substrate from 0.2 to 1.5 l / m² for a proper evaluation absorption tests will have to be carried out. With the Karsten tube absorption test(Technical data sheet n ° 224 C.S.T.C.). Remark ALL GLASS ELEMENTS SHOULD BE PROTECTED. RC 224 causes irreversible stains on blue stone and nonporous surfaces. RC 224 is not crack bridging. Technical information Basis: (alkylalcoxy) siloxane. Active matter: 10% actives. Solvent: Low aromatic hydrocarbon. Colour: Colorless product. Color applied: Invisible.
