WACKER® MQ 803 TF

WACKER® MQ 803 TF is a co-hydrolysis product of tetraalkoxy silane (Q unit) and trimethylalkoxy silane (M unit). The chemical structure of WACKER® MQ 803 TF 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 WACKER® MQ 803 TF.

 

WACKER® MQ 803 TF 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, WACKER® MQ 803 TF exhibits excellent rheological properties (flowability). Therefore, common powder processing techniques like bottling, conveying, and metering are simplified.

 

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

In technical applications, WACKER® MQ 803 TF can be used as a basic material for foam stabilizing agents.

 

For polishes, WACKER® MQ 803 TF is an excellent additive to enhance the water repellent properties of automotive and domestic care systems.

 

In compositions, WACKER® MQ 803 TF acts as an extremely efficient and most compatible release active for plastics processing. Especially for PUR processing, it can be used to formulate release concentrates, high-solids, and solvent based anti-stick agents which exhibit excellent release characteristics and do not cause build-up on the mould or any disorders on the surface of moulded articles. Bondability and paintability of the moulded articles mainly depend on the release agent composition and the paint or bonding system applied, and have to be tested in any individual case.
