Please contact Rhodia Silicones Release Coatings for specific details. Once generated, this aerosol spreads in the ambient atmosphere and propagates along the paper web. As far the mechanisms involved in the misting phenomenon, our experience, along with the scientific literature, indicate that the fluid viscosity and elasticity are critical factors. We are actively developing products that reduce or eliminate this phenomenon altogether. If you are experiencing misting problems with your current silicone products, please contact us so that we can discuss possible remedies to reduce or eliminate these problems.
Many factors determine bath stability.
Some primary factors are the bath temperature, the amount of inhibitor in the formulation, and the amount of shear force generated by the coating equipment. To guard against bath stability problems during coating, we recommend that our customers prepare, as needed, many small batches of coating bath rather than one large bath. By following this protocol, bath stability problems are minimized or eliminated altogether. Rhodia has pioneered on-machine coating applications. At present, we have most of the European market for this application.
