Coated Aluminum Sheet – Fully water-soluble product

Relying on an efficient water-soluble formula, the coating layer can be completely dissolved after being left 

in a normal temperature water environment for 180 seconds. The dissolution efficiency is about 30% higher than 

that of similar products on the market, avoiding the impact of residue issues on subsequent processes
