Anodizing and dyeing process for aluminum surface and color designs

Aluminum is used in a wide range of applications from housewares, aircrafts and medical and electronics fields because of light weight, excellent workability, non-magnetism. high electrical and thermal conductivity.

Especially, sophisticated and stylish designs are very popular for smartphones and computers, and dyed and colored aluminum are widely used for the purpose. As a global leader for aluminum surface treatment, we deliver any of chemicals for aluminum from surface improvements, coloring, dyeing and sealing to make the most innovative products with our customers.

Anodizing and dyeing process for aluminum surface and color designs

  • DegreasingProduct name TOP ALCLEAN series, TOP GREENAL CLEAN 100

    Remove oils, fat and dirt from aluminum surface.
    We have TOP GREENAL CLEAN, a phosphorus and boron free cleaner. It is an environmentally friendly product that can decrease burden in wastewater treatment.

    Degreasing

  • Etching

    Generally with sodium hydroxide solution, etch and remove the segregation layers and natural oxide films on the surface.

    Etching

  • Chemical polishing and quality improvements (Brightness, gloss degree, hand-touch feeling) Product name ALGLOSS S-200, ALSATIN series, TOP GREENAL GLOSS 300,TOP GREENAL SATIN 200

    Chemical polishing is conducted to obtain glossy or matte (pearly or satin) appearances.
    We have TOP GREENAL series that don’t contain fluorides and phosphoric acid.

    Chemical polishing and quality improvements

  • DesmuttingProduct name TOP DESMUT N-20, TOP GREENAL DESMUT 400

    Remove smut resulted from alloying elements such as copper, zinc or silicon in aluminum.
    We have TOP GREENAL DESMUT 400 for easy wastewater treatment, a desmutting agent that is not nitric-acid based.

    Desmutting

  • AnodizingProduct name ALMIST W

    Generally with sulfuric acid baths, conduct anodizing treatment.
    Transparent and porous layers are formed on aluminum, and the oxide films have ultra-micro pores in nanometer size.

    Anodizing

  • Dyeing and coloringProduct name TAC DYESTUFF

    Immerse aluminum into dyeing solution to make coloring dyes absorbed into micro-pores.
    For this step, we have a foaming preventing agent (TAC ANTIFOAM), a mold preventing agent (TAC KABIKORON-3), and a pH controlling agent (TAC CONTROLLER PH-5HS) and other related products.
    Also, we have a sunlight resistance improvers (TAC STABILIZER and TAC SUNBLOCK 88).

    Dyeing and coloring

  • SealingProduct na,e TOP SEAL series

    Oxidized aluminum is hydrated at the insides of ultra-micro pores, also nickel hydroxide deposits near the top of the pores. By these reactions, dyes are stuffed into holes and corrosion resistance is enhanced.
    Generally, nickel-acetate based sealers are used for sealing.
    We have nickel-free sealing agents such as TOP NF SEAL S-205 and TOP NF FIX F-25.

    Sealing

  • Sliding, lubricating property/corrosion resistance improvement or powdering prevention Product name TOP CACIRAS-3, TOP LUBREND-3, TOP ANOCOAT, TOP SEAL CLEAN, SEAL DOCTOR 45

    We have various products for the improvements of sliding and lubricating property, corrosion resistance, as well as powdering preventing agents.
