LIOSIL® eco MQ 803

LIOSIL® eco MQ 803 is a co-hydrolysis product of tetraalkoxy silane (Q unit) and trimethylalkoxy silane (M unit). The chemical structure of LIOSIL® eco MQ 803 can be seen as a three dimensional network of polysilicic acid units which are endblocked with trimethylsilyl groups. Some residual ethoxy and hydroxy functions are present. The average molecular weight can be exactly controlled by the ratio of M and Q units. This ratio approx. is 0.67 for LIOSIL® eco MQ 803.

In manufacturing LIOSIL® eco MQ 803, 100 % of the fossil-based raw materials are substituted by renewable raw materials (biomethanol) based on a REDcert² biomass balance approach audited by TÜV NORD.

LIOSIL® eco MQ 803 is a pure white powder manufactured substantially free of volatile impurities. It therefore only contains traces of aliphatic hydrocarbons. According to its low content of fine dust particles and its uniform spherical particle shape, LIOSIL® eco MQ 803 exhibits excellent rheological properties (flowability). Therefore, common powder processing techniques like bottling, conveying, and metering are simplified.

LIOSIL® eco MQ 803 can be dissolved in polydimethylsiloxanes or further appropriate solvents like non-aromatic hydrocarbons or lower alcohols. The solubility of WACKER® MQ 803 TF is excellent.
