Provided is a black coupling member for vehicles, comprising a trivalent chromium black chemical conversion film and a black coating film upon the trivalent chromium black chemical conversion film, on the surface of a zinc-plated metal substrate. The trivalent chromium black chemical conversion film is formed using a hexavalent chromium-free trivalent chromium black chemical conversion treatment solution having a Zn ion concentration of no more than 20 g/L. The lightness (L) of the trivalent chromium black chemical conversion film is no more than 33. The black coating film includes a black chemical conversion component, a modified organopolysiloxane, and a friction coefficient-adjustment component. The black chemical conversion component content is 2-25 wt % relative to 100 wt % of the black coating film. The lightness (L) is no more than 28.

Black coupling member for vehicles, having excellent corrosion resistance and black appearance

An object is to provide a technique capable of forming a film having a dark black appearance and high corrosion resistance on a zinc plated component in a simple process, and a black coating film-forming vehicle component and/or fastening component that is obtained by: treating a surface of a zinc plated metal substrate with a black chemical conversion treatment agent containing trivalent chromium as an active ingredient, to form a black chemical conversion treatment film having an L value (brightness) of from 33 to 30; coating a black coating composition containing a black pigment in an amount of from 25 to 65% by weight in a thermosetting film-forming component and an alkoxysilane oligomer, on the black chemical conversion treatment film; and heat-curing the black coating composition thus coated.

Black coating film-forming vehicle component and/or fastening component, and manufacturing method thereof

The present invention relates to heat-resistant paint which is capable of forming paint film that inhibits whitening even in high-temperature environments on the order of 350-650&#xb0; C. The heat-resistant paint of the present invention contains silicone resin and/or epoxy resin as well as black pigment, wherein, said black pigment contains manganese and copper, the content of manganese in said black pigment is 25-45 mass % by MnO conversion, the content of copper in said black pigment is 5-25 mass % by CuO conversion, and the content of silicon in said black pigment is 3 mass % or less by SiOconversion.

Heat-resistant paint

The present invention is intended to provide a metal gasket material plate with which exfoliation of the coating or blister can be prevented even if it is used in the presence of an electrolyte aqueous solution and which can be manufactured through a process without use of hexavalent chromium in consideration of the environment, etc. The present, invention relates to a metal gasket material plate comprising a metal platehaving a rubber layeron one side or both sides thereof through an adhesive layer, wherein a rust-resistant pigment is added to both of said adhesive layerand said rubber layer

Metal gasket material plate and method for manufacturing the same

To adopt die casts product as parts of a vehicle body frame. A vehicle body frame is provide with an alumite treating, showing that brightness and appearance of pivot plates which are die cast products differ from those of non-die cast products, head pipes, longitudinal pipes and cross pipe. By carrying out a local coating treatment on the pivot plates, the pivot plates are provided with a color the same as that of the pipe, the longitudinal pipes and the cross pipe. By making die cast products portion of constituent parts, the fabrication cost of the vehicle body frame can be reduced.

Vehicle body frame for motorcycle and it fabrication method

An isocyanate-curing coating material is disclosed which essentially consists of (A) an agent formed of a hydroxyl group-containing polymer having a weight average molecular weight in the range of 1000-20000 and (B) a polyisocyanate compound as a curing agent containing at least three isocyanate groups in the molecular unit thereof and having a weight average molecular weight in the range of 400-3000 and incorporating (A) the agent and (B) the curing agent in such amounts that the isocyanate groups in (B) the curing agent amounts to 0.5-2 equivalent weights per equivalent weight of the hydroxyl group in (A) the agent. A method for spray coating the isocyanate-curing coating material is also disclosed which comprises the steps of mixing (A) the agent with (B) the curing agent in a coating device, heating the resultant mixture therein to a temperature in the range of 35-80.degree. C., and spraying the hot mixture directly on a given object with the coating device.
