"Breathe" silicone waterproofcoating
Wall material absorbs moisture will causeserious damage to the wall itself, needs the moisture in the wall of a flowchannel in the form of water vapor evaporation from the wall material.Therefore, reducing the water absorption of building materials, exterior wallmaterials given "breathing" function, is to improve the buildingdecoration, waterproof important way. Silicone Coating with organopolysiloxanewith certain reactive groups as the main film-forming material, its backbonestructure has a strong chemical affinity, and a small amount of active groupson the molecules in the film forming process and silicon reactive with thehydroxy acid substrate. Coating the capillary channel should not be closed, thewater within the substrate to diffuse outward in time, to ensure a good base"breathing" function. Sun et al examined the new"breathing" properties and water-resistant silicone coatings, provethat the coating can be used for exterior protection of high-grade buildings.In a building with a silicone resin film formed on the surface layer ofmaterial, which can effectively improve the performance of buildings surfaceweathering (weathering resistance, and acid rain soaking rain erosioncapacity), especially for high-end architectural protection of ancientbuildings it has a certain practical Value.
