WACKER® MQ 803 TF

1 of 217 products in this brand
WACKER® MQ 803 TF is a co-hydrolysis product of tetraalkoxy silane (Q unit) and trimethylalkoxy silane (M unit). Its chemical structure forms a three-dimensional network of polysilicic acid units, which are endblocked with trimethylsilyl groups. The product contains residual ethoxy and hydroxy functions. The average molecular weight can be precisely controlled by adjusting the ratio of M and Q units, with WACKER® MQ 803 TF having a ratio of approximately 0.67. WACKER® MQ 803 TF is a pure white powder that is manufactured to be largely free of volatile impurities, containing only trace amounts of aliphatic hydrocarbons. The product's low presence of fine dust particles and its uniform spherical particle shape contribute to its excellent rheological properties, particularly its flowability. As a result, common powder processing techniques such as bottling, conveying, and metering are simplified.

Application Details
  • 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 mold or any disorders on the surface of molded articles. Bondability and paintability of the molded articles mainly depend on the release agent composition and the paint or bonding system applied, and have to be tested in any individual case.
