BELSIL® TMS 803
BELSIL® TMS 803 is the co-hydrolysis product of tetraalkoxysilane (Q unit) and trimethylethoxysilane (M unit). The chemical structure of BELSIL® TMS 803 can be seen as a three-dimensional network of polysilic acid units, which are endblocked with trimethylsilyl groups. Some residual ethoxy and hydroxy functions are present.
BELSIL® TMS 803 is a white powder manufactured in such a way that it is substantially free of aromatic solvents such as toluene. In keeping with its low content of fine dust particles and its uniform particles, BELSIL® TMS 803 exhibits excellent rheological properties (flowability).
BELSIL® TMS 803 can be compounded with polydimethylsiloxanes.
