New Alkaline etching additives
New Alkaline etching additives is designed to meet the requirements of common alkali corrosion or matte alkali corrosion of aluminum profile surface treatment and develop the functions of comprehensive leveling and corrosion inhibiting surface activation of chromium-aluminum ion, etc., to meet the requirements of various forms of aluminum surface pretreatment, the highest amount of aluminum dissolving is 140g/L
Aluminum Solid Alkali Etching Agent
BS-Q05 New Alkaline etching additives is Light yellow liquid or white solid. It is used for avoiding the scale formation and has an aluminum ion complexing power over 120g/L. The additive can improve the etching quality, decrease the aluminum loss and the consumption of alkali. It is eco-friendly.
