Total Process and Specialized Additives
Etching:
Generally with sodium hydroxide solution, etch and remove the segregation layers and natural oxide films on the surface.
Products: ALSATIN SK, ALSATIN L, etc.
Chemical Polishing:
Chemical polishing is conducted to obtain glossy or matte (pearly or satin) appearances.
Products: ALGLOSS S-200, etc.
Desmutting:
Remove smut resulted from alloying elements such as copper, zinc or silicon in aluminum.
Products: TOP DESMUT N-20, etc.
Anodizing:
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.
Products: ALMIST W, etc.
Surface Conditioning:
Removes the sulfuric acid that remain on the surface and in the micro pores.
Products: TAC SORMAL 244, TAC SORMAL 121, etc.
Dyeing and Coloring:
Immerse aluminum into dyeing solution to make coloring dyes absorbed into micro-pores.
Products: TAC DYESTUFF, TAC STABILIZER, etc.
Sealing:
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.
Products: TOP SEAL DX-500, TOP SEAL E-125, etc.
