Бэлэн байхгүй
Nukote Chemshield CW compounds are paste of metals and ceramic in a polymeric binder to be used as a repair, rebuild and resurfacing product, providing excellent performance in corrosive, chemical and abrasive environments, at ambient or elevated temperatures for both ferrous as well as nonferrous metals. These products are designed for industrial use at elevated temperatures and will maintain its physical properties under continued exposure to high constant temperature both in exposed as well as immersion conditions. Nukote Chemshield Cold weld compounds are resistant to many solvent, chemicals including hydrochloric, sulphuric acid, alkalis, mineral spirits, cutting oil, sulphur fumes, seawater, in ambient as well as elevated temperatures. The products are available in different grades and specific purposes. Chemshield CW is used as a high strength structural adhesive and also suitable in cryogenic applications. This product can be used in most applications in combinations with other nukote ceramic coating assortments.
