Product Description
Coomcool RST DW 15 is a dewatering agent, which leaves no perceptible film upon evaporation.
Advantages
- Excellent water displacing and penetrating properties.
- Economical and efficient alternative to compressed air drying.
- Complete absence of water spots when dewatering sensitive surfaces, such as polished glass or chromiumplated components.
- Does not hinder adhesion of paint or other subsequent protective coatings.
- High stability against acidic and alkaline contaminations, highly suitable for the electro-plating industry.
Applications
Coomcool RST DW 15 specifically can be used for the treatment of surfaces which cannot be subjected to heat to accelerate drying, and also avoids the formation of water spots upon polished or plated components.Although Coomcool RST DW 15 can be applied by spraying, its dewatering action is most effective if articles to be dried can be immersed in a dip tank.
Coomcool RST DW 15 rapidly removes water from components subsequent to electroplating processes, after machining using soluble cutting fluids, or parts that have been washed.
