Performance characteristics of oligoorganohydridesiloxanes

The hydrolysate is separated from HCI dissolved in water washed, neutralised and dried. The dried product is marketable liquid GKZh-94. This technology is based on the fact that GKZh-94 cannot be heated to distil volatile products due to gel formation. Well-washed, neutralised and dried liquid under normal conditions can be stored over a long period of time retaining its properties. 

Oligomethylhydridesiloxane (GKZh-94M), which as a waterproofing agent is not as universal as GKZh-94, has greater reactivity and other specific properties. 

The main spheres of alkylhydridesiloxane application can be separated into two groups in civil engineering and in the light and textile industries. In both spheres the substances yield considerable technical and economic results, but their ways of application are different. 

In order to describe the reactions of waterproofing materials with alkyl-hydridesiloxanes, let us consider the interaction of the =Si-H bond with different functional groups. If a negative ligand is introduced, the silicon atom with its larger volume receives a positive charge due to polarisation, 

These catalysts are the alkoxyderivatives of aluminum, titanium, lead, tin. This study shows that the interaction of oligoalkylhydridesiloxane with tetrabutoxytitanium first forms coordination bonds due to the donor-acceptor interaction of the titanium atom with the oxygen atoms in oligosi-loxane. This is followed by the polymerisation of oligosiloxane, which forms a spatially cross-linked polymer.
