The chemical structure of the siliconeresin is between inorganic and organic molecular structure of quartz as a reference,a main chain composed of silicon and oxygen atoms, therefore all the siliconeresin other than silicone having more inorganic properties. After 1009 siliconecombustion, the remaining approximately 909 silica, which is a silicone resinpaint with superior weather resistance provide a guarantee structure. Siliconeresin structures different from that of quartz every four oxygen atoms have a"0" would be replaced by a hydrophobic organic group. Siliconepolymer chain has a lot of hydroxyl groups, these groups to ensure that thesilicone resin capable of solid pigment and filler particles firmly adhere tothe materials is very important. Pigment and filler particles to the surface ofhard mineral building materials contain hydroxyl groups after these hydroxylgroups can react chemically with the silicone resin of a hydroxyl groupprolapse water. Thus, the silicone resin can be firmly and pigments, fillersand materials phase bonding. Meanwhile, the silicone polymer and watermolecules react with the hydroxyl groups remain. This is the resincross-linking molecules in multi-point, forming a typical three-dimensionalsilicone resin network. From the molecular level point of view, the surface ofthe filler particles can be produced by bonding the inorganic portion of thesilicon-oxygen bond with silicone. Inorganic portion of the silicone throughthe capillary pores and cavities "coverage" and thus serve tostrengthen the role of the filler, also known as "micro enhanced"performance. These trifunctional silicon-oxygen bond capable of bonding withthe particle surface. Silicone organic groups as small umbrella-like eleveninternal projection from the hole to the surface, the surface of the organicgroup has hydrophobic properties. These two phenomena, microporous hydrophobicand enhanced microporous structure, it is the secret of the success of siliconecoatings.
