chemicals for passivating the aluminum surface before powder coating

Environment-friendly Aluminum Passivator

IC-2012

Environmentally friendly aluminum passivator ------ liquid, Cr-free⁺⁶

Iperformance and application  

IC-2012It is a liquid product for passivation treatment, suitable for the chemical conversion coating process of aluminum and its alloys, and does not contain Cr+6. When mixed with water, it forms an amorphous inorganic coating on metal surfaces when dipped and sprayed. The coating has the following functions:

* Good adhesion to paint coatings and good corrosion resistance.

* Bare plating has strong corrosion resistance.

* The coating has a low conductive resistance.

IC-2012 can be used in dipping or spraying process.

IC-2012 coating is colored, depending on alloy composition and operating conditions

Vdrying

After the components of the bath liquid react completely with the aluminum surface, rinse the excess surface with deionized water until the conductivity of the water to the surface of the workpiece is less than 25us/cm. Finally, dry the workpiece (5-20 minutes, 60~90℃) before painting. Gloves must be worn after painting to remove marks on the workpiece. The processed workpiece should be painted during the day.

 sixHandling safety

IC-2012 is a fluorine-containing acidic product. Splash accidents or contact with skin or eyes may cause burns.

In case of accidental contact with the skin, wash off with water immediately, and then massage with 2.5% calcium gluconate gel for a few minutes. If it accidentally splashes into the eyes, rinse with water immediately, and then seek medical attention with 2% triethanolamine eye drops.

It is recommended to wear gloves, protective glasses, protective clothing and safety shoes during operation.

Install showers and eyewash stations near the workplace.

Do not use glass or silicon containers.

7. Storage

IC-2012 must be kept in the original sealed container in a well-ventilated environment.

This product is sensitive to cold, and it can still be heated and stirred after freezing without affecting performance.

Stay away from alkaline products.

Eight sewage treatment

The procedure is as follows:

*Use lime to neutralize the precipitated fluorine and metal salts, and control the pH value at 6.5~9

*Let the sediment sit on the bottom.

After processing, check whether the indicators comply with local regulations.
