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, prove that the coating can beused for exterior protection of high-grade buildings. In a building with asilicone resin film formed on the surface layer of material, which caneffectively improve the performance of buildings surface weathering (weatheringresistance, and acid rain soaking rain erosion capacity), especially forhigh-end architectural protection of ancient buildings it has a certainpractical Value.
