model/specification

AL-EE

characteristics

The surface of aluminum or aluminum alloy treated with the milky white sand remover AL-EE can produce a beautiful milky white effect.

• Through simple dipping treatment, a milky white effect can be obtained.
• No irritating smoke or harmful gases are produced.
• It can remove scratches and roll marks on the surface of the substrate.
• The solution is stable and the surface treatment effect is uniform.

conditions of use

Process flow:

Degreasing → washing → acid immersion →AL-EE treatment → water washing → acid immersion → water washing → anodic oxidation

Degreasing:

It is recommended to use solvent or neutral degreasing, such as alkaline degreasing, and fully neutralize after degreasing.

Wash:

After degreasing, it can be treated by heating, electrolysis, emulsification and other washing methods according to actual conditions.

Acid impregnation:

Stir the workpiece in a water washing tank, and then soak it in a mixture containing 10% nitric acid and 5% fluorine acid for 10-20 seconds. (Please wear protective equipment when preparing acid.)

Opal milk treatment:

After fully washing with water, place it in AL-EE solution for treatment at 18-30℃ for 1-5 minutes. (Keep stirring during processing, otherwise spots and flaws will occur, such as rising liquid temperature, shortening immersion time).

Acid impregnation: After sufficient water washing, soak in acid solution (same as point 3) for 3-5 seconds, and conduct anodic oxidation. Through the above process, a stable treatment effect can be obtained.

package and storage

25 kg/bag, stored in a cool and dry warehouse, strictly prohibited from direct sunlight, high temperatures and high temperatures, must be covered and sealed after use.
