Antitack BTO-33
Antitack BTO-33 does not contain any heavy metal ions and can therefore replace zinc stearate dispersions. This antitack agent was developed considering latest ecological aspects. All included ingredients are biodegradable.
The particularity of Antitack BTO-33 is that the magnesium stearate particles are partially hydrophobic due to the special production process. After dilution in water the pigments rise to the upper levels of the antitack bath. Therefore the uncured rubber sheets always pass an area of high concentration and get treated very well. The partial hydrophobic character also leads to a faster drying of the layer on treated rubber parts.
Due to the strong layer on the rubber surface it can be controlled visual. We recommend an incorporation of the antitack agent before vulcanization.
The magnesium stearate melts during vulcanization and most of it is absorbed by the compound. The melting point of the pure magnesium stearate is approx. 135 °C. We noticed in our trials that the material of the layer on rubber is a eutectic mixture which melts already at 90 °C. If the recommended dilution ratio is used, the physical properties of the compounds are not influenced. When using Antitack BTO-36 in batch-off dip tanks we recommend to circulate (pump or stir) the antitack bath.
For first trials we recommend a dilution ratio of about 1:10 (Antitack BTO-33:H2O).
