Co-Formula has successfully synthesized a series of long-chain functional silanes including octyl(C8), dodecyl(C12) and octadecyl(C18) silanes.

Long-chain organofunctional silanes at Co-Formula have gained great reputation in construction industry. Such long-chain silanes can be used in the formulation of water repellent products when diluted with an appropriate solvent. Under proper application, the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate. Treated substrates are hydrophobic and retain their original appearance.CFS-751, Octyltriethoxysilane with Cas No. 2943-75-1 is the most common hydrophobing agent in the market. Acting as a surface modifier and a protecting agent, it can generate hydrophobicity on concrete, ceramic and glasses. Better

ong SAmong these silanes, CFS-088, Octadecyldimethylchlorosilane with Cas No. 18643-08-8 is warmly welcomed during the preparation of reversed-phase C18 chromatographic columns (ODS). CFS-088 has been synthesized for micro and nanoparticles derivatization, silica modification and molecular monolayers generation. Silica treated with C18 based on ODS column can enhance durability and bring excellent performance.
