数据表
In surfactant-rich formulations, such as liquid detergents and textile auxiliaries. SILFOAM® SE 39 is particularly suitable for applications in which high surfactant concentrations or intensive product movement would cause conventional antifoam emulsions to become rapidly ineffective.
Processing
SILFOAM® SE 39 is a low-viscosity emulsion, it can be metered readily, with stable dispersions easily attainable in high-viscosity formulations. In low-viscosity products, preliminary compatibility and stability tests should be performed on the system to be defoamed.
The amount to add to liquid formulations depends on the desired degree of foam control, but usually lies between 0.1 and 2 %. If SILFOAM® SE 39 is to be added during a process, we recommend prediluting it with cold water in a ratio of 1:1 to 1:10. These diluted emulsions have a lower storage stability and should be processed as close in time as possible. If feed pumps are used, they should be of the low shear force type.
储存
The "Best use before end" date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
