hi, I am yuebingke at hn jyd chem factory
we do thermochromic leuco dye chemicial for thermochromic items( x ray film, powder, ink , paint ) . hope get your connection if it is useful for your company . thanks very much.
leuco dye apperance is white crystal . it cannt forms the color directly.
frst they need en-micocapsulated need work with some acide solvent to forms color or color less.
our chemical leuco dye mostly used in some factory industries who have microcapsulate machine and coating machine such as the x ray film , cpt plate mills .

We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
