BELSIL® eco TMS 803 is a co-hydrolysis product derived from tetraalkoxysilane (Q unit) and trimethylethoxysilane (M unit). Its chemical structure forms a three-dimensional network of polysilic acid units, which are capped with trimethylsilyl groups. Some residual ethoxy and hydroxy functionalities are also present. This product is based on renewable raw materials and adheres to the "TÜV NORD Standard REDcert²." It is a white powder that is manufactured to be largely free of aromatic solvents like toluene. It possesses excellent rheological properties thanks to its low content of fine dust particles and uniform particle size distribution, ensuring good flowability. Additionally, BELSIL® eco TMS 803 can be blended with polydimethylsiloxanes.
