Alkali etching additives

Composed of various complexing agents, corrosion inhibitors, brightness regulator, cleaning agents and surface active agent. It has the following advantages, while comparing with the traditional alkaline etching agents:1. Long life using and eliminate scratch on Aluminum profile. Capable of using on glossy and mat suface.2. Stronger aluminum ion complexation capacity. Able to achieved 140 g / l without precipitation.3. Using suitable surfactant, corrosion inhibitor. Easily flow away from Aluminum profile while removal.4. Easier control for bath process, low Aluminum consumption, easy maintenance and management.
