Product Name: Medium and High Temperature Sealing Agent
Model/Specification: FK003
Product Features:
FK003, a medium high temperature sealing agent, is a nickel containing light green powder that is easily soluble in water and suitable for sealing after aluminum oxidation dyeing.
This product has the following advantages: it has a sealing effect with less color flow and less gray hanging.
After sealing, the surface of the aluminum sheet feels smooth and has excellent hydrophobicity.

Usage conditions:

Preparation of tank solution:
It is best to use deionized water or tap water for the new tank solution, but the effect is slightly inferior.

Packaging and Storage:
10kg/box, stored in a cool and dry warehouse, strictly prohibited from direct sunlight, high temperature and heat. After use, it must be covered and sealed.

Management:
1. Accurately measure 10 milliliters of solution and add it to a conical flask.
2. Add approximately 150mL of deionized water, 10mL of 25% -28% ammonia water, and a small amount of ammonium purple urea indicator to the conical flask.
3. Shake well and titrate with 0.0100mol/L EDTA-2Na. The endpoint is reached when the solution changes from light yellow to light purple.
Calculation: C (FK003)=c * V * 34.09
C is the concentration of the sealing agent solution - g/L, c is the mass concentration of EDTA - mol/L, and V is the volume of EDTA consumed - mL.
