Copper Conductive Paint, Restores High Conductivity, Rapid Drying,0.33 oz

Save Your Rear Window Defroster Without Replacing the Glass!Is your car's rear window defroster malfunctioning? Have you been told you need to replace the entire expensive rear window because of a few broken defroster lines? Copper conductive paint restores the integrity of the circuit by "drawing" a new conductive path at the break, allowing current to bypass the break point.How to Use:1.Locate the break in the rear window defroster line and thoroughly clean the break and surrounding area, ensuring it is clean and dry.2.Use low-viscosity masking tape to cover both sides of the broken line; this will help you draw a straighter, more precise line.3.Shake or stir the conductive paint thoroughly. Apply a suitable amount of paint evenly to the break with a brush, connecting the two ends of the line. The coating does not need to be too thick; just enough to completely cover the break.4.Wait for it to cure. It will conduct electricity once fully cured.5.After curing, activate the car's rear window defroster function and check if the repaired line heats up and if the fog has been effectively cleared.Precautions1.Please note that the conductivity of copper conductive paint may decrease slightly over time due to oxidation of copper particles. To maintain optimal performance over the long term, we recommend sealing the container tightly after each use and storing it in a well-ventilated, dry indoor environment2.Ensure the surface to be repaired is absolutely clean and dry; otherwise, it will affect the adhesion and conductivity of the conductive paint.3.Practice on scrap glass before first use or repairing critical areas.4.Immediately after use, tightly close the cap and store in a cool, dry place, away from direct sunlight.5.Ensure the rear window defroster switch is completely turned off before operation to prevent short circuit risk.Q&AQ: What is this copper paint used for?A: Fixing broken rear window defroster lines. If one line is scratched or broken, just brush this on to reconnect it.Q: Does it actually conduct electricity?A: Yes. It's made with high-purity copper powder, so current flows smoothly. The defroster works just like new.Q: Is it easy to use?A: Super easy. Clean the area, shake the bottle, brush a little over the break, and let it dry.Q: How long does it take to dry?A: Surface dry in 15 minutes. Bake at 150°F for 30 minutes if you want it faster. Fully cured in 24 hours.Q: Will it last?A: Yes. It handles car vibrations, washes, and weather changes just fine.Q: What comes in the kit?A: Copper paint, masking tape, and a scraper. Everything you need for one repair job.Q: Will the conductivity decrease over time?A: Copper particles may oxidize slightly over time, which could mildly affect conductivity. To minimize this, always seal the container tightly and store it in a dry, ventilated indoor environment when not in use. This helps maintain long-term performance and ensures reliable repairs.

• Precise Repair of Defrosting Lines: When a line breaks due to scratches or aging, causing the window defrosting function to fail, simply use a brush to trace the break to rebuild the conductive path and restore the function of the entire defrosting grid
• High Conductivity: Copper conductive paint contains high-purity copper powder, ensuring excellent conductivity of the repaired line, allowing for smooth current flow and making the defrosting effect indistinguishable from the original line
• Strong Adhesion and Durability: The repaired coating is wear-resistant and weather-resistant, able to withstand vibrations from vehicle driving, car washes, and weather changes, providing a long-lasting and reliable repair effect. To maintain optimal conductivity over extended use, please note that copper particles may oxidize slightly over time, which could mildly affect conductivity. We recommend sealing the product tightly and storing it in a well-ventilated, dry indoor environment when not in use
• Easy to Use: Clean the substrate surface and thoroughly shake or stir the conductive paint. Apply an appropriate amount of conductive paint evenly to the damaged area with a brush, connecting both ends of the conduit, and allow it to cure
• Quick Drying: Surface drying takes only 15 minutes, with a baking time of 30 minutes at 65 degrees Celsius, and complete curing and usability within 24 hours
