Silicate-Siloxane copolymers having hydrophobic properties


  • Neue Materialien

For the first time the reaction of oligodymethylsiloxanes with silicates was carried out, leading to formation of silicate-siloxane copolymers, having hydrophobic properties.

After the solutions are dried out, a solid water-resistant polymer is obtained, which is suitable to form adhesive binding between fiber/filaments forming the structure of mineral cotton lagging. There were carried out testing of new polymer properties, which showed, that the new polymer demonstrates high durability and incombustibility; the thermal destruction starts at 530C. It also demonstrates high adhesion towards mineral cotton, concrete, glass, gypsum and wood as well as nonwettabillity towards most of plastics and metals. Due to the high molecular share of silicates it costs not higher than phenol-formaldehyde resin.
