Which material is used for masking of hard plating?
Plastic tapes are the most commonly employed masking devices in plating and anodizing facilities.
Can you anodize at home?
Anodizing works particularly well with aluminum, so, if careful, you can do it at home. Use small aluminum pieces to begin with so that you can submerge it in small quantities of acid. You can find small aluminum parts for this purpose relatively affordably from most home improvement stores, as well as online.
What acid is used for anodizing?

Sulfuric Acid is the preferred method among anodizers The predominant anodizing process today. Coatings 0.1-1.0 mil thick formed in a 15 pct.
What is splash anodizing?
Splash anodise is done using different colored printing inks. Anodise as normal and then dry out; then dribble on one color, then another and as many as you like; then dye completely then apply the dark color then remove the excess ink by soaking in a solvent then seal in a nickel acetate solution.
Can titanium be anodized twice?

What is masking lacquer?
Masking Lacquer is used to protect and cover areas which are not to be plated during the electroplating process. It is a type of liquid metal masking which requires a more precise application. Different masking lacquers and thinners are made to withstand different conditions, from high temperatures to acidity.
Which type of the masking agent is used for Aluminium?
Answer: For the selective demasking of aluminium, we employed triethanolamine, which also reacts with iron. To avoid interference by iron, ascorbic acid was added before the addition of KCN, ensuring that iron and manganese (if present) are reduced and complex with cyanide.
Will vinegar remove anodizing?
How to de-annodize without damage – HeliFreak. I’ve seen this done with sodium hydroxide and vinegar. I have found a degreaser that will remove annodizing without discoloring aluminum. It takes about 45 minutes, then I use a pencil eraser to polish the aluminum.
