Anti-Tarnish Degreaser for Non-Ferrous Metals - Heavy Oil Removal

a)       Anti-Tarnish Protection for Sensitive Metals

Designed with a temporary protective mechanism, 6681 prevents oxidation discoloration on non-ferrous metals during cleaning:

• It avoids unsightly flaws like aluminum gray spots and copper oxide black dots, preserving the original luster and surface integrity of workpieces. 

• This eliminates rework and scrap caused by discoloration, reducing the need for additional anti-oxidation processes and improving final product acceptance rates.

b)       Powerful & Efficient Heavy Oil Removal

The advanced formula quickly penetrates and emulsifies stubborn industrial greases, including cutting oil, stamping oil, metalworking fluid, and carbon deposits:

• It requires no prolonged soaking, significantly shortening cleaning cycles and adapting to spray, ultrasonic, and immersion cleaning equipment. 

• For high-volume production lines, this efficiency translates to less downtime, faster workflow, and reduced labor and time costs.

c)       Non-Corrosive & Multi-Material Compatible

6681 is gentle on sensitive non-ferrous metals—safe for aluminum alloy, pure copper, copper alloy, and brass without causing corrosion or damaging surface precision or natural protective films:

• A single product meets the cleaning needs of multiple materials, simplifying inventory management, reducing procurement complexity, and lowering overall purchasing costs for businesses.

d)       Eco-Friendly & User-Safe Formula

As a water-based, non-flammable cleaner, 6681 features low volatile odor for a safer working environment. Tested and verified, it contains no heavy metals or halogens, aligning with global environmental trends. This eco-friendly attribute not only protects operators but also eases customs clearance and compliance concerns in target markets, ensuring peace of mind during use.

1)       Target Materials: 

Aluminum alloy, pure copper, copper alloy, brass, and other non-ferrous metal workpieces and equipment.

2)       Key Industries: 

Automotive parts manufacturing (engine aluminum components, copper connectors), electronic component processing, precision hardware stamping, and general machinery manufacturing.

3)       Cleaning Objects: 

Heavy oil-contaminated workpieces, precision components, and oil-stained surfaces of production equipment.

1)       Dilution Ratio: 

Mix 1 part 6681 with 5 parts water for heavy oil contamination, or 1 part 6681 with 20 parts water for light soiling. Stir thoroughly until uniform.

2)       Application Methods:

• Spray cleaning: Apply diluted solution to contaminated surfaces and rinse after 3-5 minutes.

• Ultrasonic cleaning: Add diluted solution to ultrasonic equipment, clean at 25-60℃ for 3-6 minutes, then rinse and dry.

• Immersion cleaning: Soak workpieces in diluted solution at room temperature to 60℃ for 4-6 minutes, followed by rinsing and drying.

3)       Precautions: 

Store in a sealed container to avoid contamination. Wear basic protective gear (gloves, goggles) during operation.
