Water soluble semi-inorganic silicon steel sheet paint

short description:

Compared with the traditional silicon steel sheet paint, 0151 paint uses tap water as solvent, does not contain chromium, phenolic resin and other environmentally unfriendly components, is a new green product; The inorganic content of 0151 paint is up to 50%, which meets FranKlin burn test. The electrical and mechanical properties are up to the technical level of similar imported products, and the heat resistance grade is H. 0151 Paint technology is excellent, can use the existing equipment, the process is simple and easy to operate and control, and the baking process of painting non-toxic tasteless, no pollution, painting equipment cleaning convenient, health and environmental protection, well received by the operator.

Before this kind of products completely dependent on imports, the successful development of 0151 water-soluble semi-inorganic silicon steel sheet paint to fill the domestic gap, it is widely used in large and medium-sized generators, turbo-generators, oversize rotary motors, magnetic suspension special traction motors, etc., is the first domestic, is the ideal material to replace imports.

Main ingredients: 0151 water-soluble semi-inorganic silicon steel sheet paint is composed of modified alkyd water-based resin, barium sulfate and other fillers, additives, co-solvents and deionized water.
