    Ethyl silicate

    (a homogeneous mixture of oligodeoxythymidine)
    Chemical formula: RO-[-Si(OR)2O-]m–R, R=C2H5
    Country of origin: Russia
    Manufacturer: Khimprom

    Ethylsilicate – transparent, low-viscosity liquid, which is a complex mixture of oligodeoxythymidine with different degree of condensation. Ethyl silicate-32 and Ethyl silicate-40 different contents of SiO2, respectively 32% and 40% by weight. Application: as a starting component in the binder solutions used for the manufacture of ceramic molds in precision casting; as a binder component in heat-resistant, chemical - and weather-resistant coatings and in other areas, where after hydrolysis in alkaline medium, drying or firing need to get a durable, solid material — not soluble in water, resistant to high temperatures and does not have corrosive action; in medicine as a binder in the manufacture of dental prostheses; in construction for the impregnation of wood with the aim of giving it a resistance to the bacteria; to improve the quality of rosin varnishes; in the leather industry for tanning dehydrated skin.
