Silazanes

SiSiB SILICONES is a worldwide leading manufacturer of silanes and silicones
for over 30 years.

SiSiB is worldwide leading silane manufacturer of organosilanes for over 30
years. SiSiB silazanes are synthesized by ammonolysis or aminolysis of
chlorosilanes. They are widely used in coating, carbonitride ceramics, surface
modifier and additives of silicone rubbers.
SiSiB silazanes are used in moisture cured release coating. They are more
reactive than conventional silicones. SiSiB silazanes even react with
water/moist air to produce silicones and ammonia.
Silazanes by SiSiB, a reliable silicone supplier, are used as blocking agent in
the manufacturing of silicone rubber. They can effectively impede the
rearranging degradation of polysiloxane chains as the reactive –SiN bond
reacts with trace water or the -SiOH group, and thus improve the thermal
stability of silicone rubbers.
SiSiB silazanes are used to modify organic intermediates to promote chemical
processing reactions more efficiently, and to modify physical properties of
finished products by incorporating silicone chemicals.
SiSiB® PC9210 (Hemamethyldisilazane, HMDS) is an extremely versatile and strong
silylating agent. It is primarily used for the protection of sensitive
functional groups during chemical synthesis, for example, cephalosporins and
prostaglandins.
One of the advantages of SiSiB® PC9210 over trimethylchlorosilane is that no
base is needed as a hydrochloric acid acceptor. SiSiB® PC9210 produces ammonia
which escapes easily from the reaction mixture during silylation.
SiSiB® PC9210 hexamethyldisilazane can be used as adhesion promoter in the
microelectronic industry and as hydrophobization agent for fillers, e.g.
silica.
SiSiB® PC9411 (Tetramethyldivinyldisilazane) is used as adhesion promoter for
Negative Photoresist.
