Sulfide fumigation color finish
(Film formation on copper + Dry sulfide coloring treatment on hairline + Clear coating)
The “sulfide fumigation” is generally provided on the copper alloys. This treatment is reappeared an atmosphere of this “sulfide fumigation” provided on the steel, aluminum and stainless steel is called “Sulfide fumigation color finish”.
The copper film is formatted by the coating, and thereafter hairline finish is provided on it.then the sulfide fumigation is provided. Because of these processes, three colors which are light color, intermediate color and dark color are obtained and these colors will show the similar appearance with an actual rested color. The feel of a hairline will be able to reappear, but it will be spoiled a certain amount of the sulfide fumigating feeling because the finish is painting base.
Available “Base materials”
Steel(for interior only), Aluminum, Stainless steel
Surface finishes on each material
Hairline (Stainless steel)
Explanation of finish
The “sulfide fumigation” is generally provided on the copper alloys (Red brass & Brass etc). This treatment is reappeared an atmosphere of this “sulfide fumigation” provided on the steel, aluminum and stainless steel is called “Sulfide fumigating color finish”.
The sulfide coloring is basically not provided except the copper alloys. Therefore, the copper film is coated on the steel, aluminum and stainless steel by the special painting method, not coloring by electrical plating. Thereafter the sulfide fumigation is provided after hairline finish. The color tone will be same as “Sulfide fumigating color” and three colors are basically light color, intermediate color and dark color. We will response to your request in case your wish to provide the atmospheres of the strong yellowish color as brass and reddish color as red-brass.
In addition, many type of luster is able to select in polishing, matt and semi-gloss. The surface condition can only be provided on hairline finish, 3S and mirror etc are not available.
Notes and others
- Our treatment on the surface is provided based on after formed, therefore, the bending, shearing and making holes process shall be done before the treatment in order to avoid peeling the sulfide film and clear coating.
- The products size will be 1,500mm(W)×5,500mm(L). And the weight is max. 100kg. If it is more than the above size or weigh, please freely contact us.
- The sulfide fumigation color is painting. The design surface will occur the aged deterioration because the copper components are painted on it. Please note that the corrosion of pock marks maybe appear on the surface. Please select the stainless steel as base material if it is using for the exterior.
- Our treatment works are provided in our factory, so we do not accept the treatment works at job site.
- The copper alloys like brass is a certain amount of color difference from yellow to red color. The certain amount of the color difference will appear in case the sulfide fumigating treatment is provided.
- The touch up work is required using the similar color of which is metallic painting having sulfide tone. Please contact us if it is necessary.
- Please don’t use the benzine, thinner, scotch and etc for the maintenance on the surface because the cause of discoloring. Please carry out the periodic cleaning by soaking a soft cloth with neutral detergent, thereafter it wipes the wet surface with dry cloth.
- In order to avoid peeling off the clear coating, please don’t use the gummed tape or masking tape on the finish.
