Applications & Uses

Product Application

Cosmonate JG-50K is a special product developed for manufacturing electrolysis paint hardener, it can be applied in CASE field such as adhesives specialized by low adhesion degree and waterproof ground material.RemarksWhat is electrolysis coating? It is a paint film formation on the ground surface by electric power, as dividing negative pole and positive pole in paint and ground needed painting, providing direct current power source in water-soluble paint. The merit of electrolysis coating is like the follwing. Coating can be equally on complex structure and even on invisible part. Thanks to automation of coating, it can save energy, thickness of painting film can be controlled by 10~30, levelness and broadness of painting film are equal compared with powder puff paint, so external appearance is fine. Also there's no running, no getting blocked, no pinhole, less loss of paint (reuse), coated on welding part, inside pipe, excellent durability, less pollution thanks to water-soluble.

Safety & Health

Safety and Health

In case of skin contact, inflammation such as an eruption can break out. In case of getting in the eye, severe painful, when exposed excessively, eyesight trouble can happen. Also in case of inhaling steam of MDI, bronchial asthma, headache, dyspnea can break out, in case of eating it, it can cause a trouble in digestive organ and inflammation. In case of skin contact, you shall wash out with great quantities of water or soapy water. And in case of contact to the eye, you shall wash out with great quantities of water or soapy water for 15minutes before go to see a doctor. Also in case of inhaling steam of MDI, you shall be moved to the fresh place, be kept safe and warm, be tried artificial respiration in need. In case of eating it, you shall eat a large quantity of water or milk, raw egg and vomit before go to see a doctor. It's not much inflammable but should be careful with fire. In case of fire extinguishing, carbonic acid gas type is appropriate. In case of big fire you shall put out a fire with water.
