Abstract: To improve the performance of zinc-rich painted steel sheets, such as Zincrometal, NKK first developed Zn-Ni alloy plated steel sheet with a thin (about 1 pm) organic-silicate composite film entirely different from a zinc-rich paint film. This product (EZN-UC) is superior to zinc-rich painted steel sheet in corrosion resistance, anti-powdering property and weldability. EZN-UC, however, is not able to provide bake hardenability due to the high curing temperature of the film. NKK has developed new organic-silicate composite coated steel sheet (EZN-UCII), which allows the coating to be cured in the temperature range where bake hardenability can be maintained. Newly developed EZN-UCII has excellent properties, such as corrosion resistant precoated steel sheet for motor car bodies. EZN-UCII attained higher corrosion resistance than EZN-UC and also provides excellent weldability and anti-powdering property equivalent to EZN-UC. NKK has been producing EZN-UCII for motor manufacturers since November 1987.
