1、 Application scope

Used for high-quality and smooth surface aluminum alloy anodizing and electrolytic coloring sealing treatment.

2、 Product features

This product is a light green powder, with good sealing effect, wide temperature range, no white frost, and higher corrosion resistance than boiling water sealing, preventing fading or discoloration. It has stable pH value, easy maintenance, long service life of the tank liquid, and low consumption. Can be used on high-quality and smooth surface aluminum materials.

3、 Traits

Light green powder, with a pungent smell of acetic acid.

4、 Operating conditions

5、 Analysis methods

1. Transfer 5ml (V1) of solution into a volumetric flask using a pipette and add 100ml of water;

2. Add 2 milliliters of triethanolamine solution; 10ml ammonia water

3. Add a small amount of ammonium purpurate indicator (1-2 grams);

4. Titrate with 0.05N (C1) EDTA until yellow to purplish red;

Calculation: TAD-500 (g/L)=C1 * V titration number * 248.86/V1;

6、 Usage and Maintenance

1. It is best to perform sealing treatment at high temperatures to minimize fading. But if the sealing time is too long, it will produce powder.

2. The pH value is between 5.4 and 6.4, and the sealing ability will not have a significant impact. If it exceeds the range, the sealing ability will decrease and powder will also be produced.

Please use acetic acid or sodium hydroxide to adjust the pH value.

7、 Packaging

This product is packaged in cardboard boxes for external use and 10kg/box with plastic packaging inside.
