Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water.

Exploit of organic silicon monomers： There are a wide variety of organic silicon monomers on the market at present. Market application is available for more than 1800 kinds of monomers, which is increasing every year. As one of domestic leaders in the field of special type monomers development, by now, Our Chemical has developed more than 500 kinds of special monomers, including some custom=made items. We have around 300 monomers in stock, which mainly cover the application in all fields.

R&D service of performance modified of organic silicon monomers： The down-stream products of organic silicon contain resins, coatings and paintings, silicone oil, rubbers, cosmetics, engineering materials, medicine/pharmaceuticals, silica gel, sealing gel, etc. We devote to provide perfect technology service to the companies of the down-stream products and help them to be better in the work of performance modified. Especially in the fields of coatings, silicone oil and engineering materials, Our Chemical has made big breakthroughs.
