Product Features and Suitable Substrates

Suitable substrates: steel plates, iron sheets, fiberglass, and existing paint layers, among others.
The high-temperature conductive paste can withstand a "baking test" at 200°C, exhibiting exceptional thermal resistance and outstanding adhesion properties.
Primarily used on surfaces of automotive engine hoods, metal components, or other substrates with high demands for thermal conductivity under elevated temperatures.

Construction Instructions

Sand the substrate ready for puttying, removing grease and moisture.
Thoroughly mix the putty with the hardener until the color is evenly consistent.
Quickly level after mixing within the workable time.
After applying and scraping, allow it to harden before sanding.
Use a polisher to gently sand the surface of the electrophoresis plate, removing any surface dust and ensuring the coated surface remains clean and dry.
Mix the putty and hardener thoroughly at a weight ratio of 100:2 until the color is uniform. Use the mixture within the recommended working time of 3 to 15 minutes. If the mixed putty begins to set—noticeably increasing resistance when you start applying it—immediately stop using it. The usable time can be influenced by ambient temperature, humidity levels, and the amount of hardener added.
Quickly press the mixed putty into the area to be applied and scrape it smooth right away. When applying, firmly pack the putty even further to eliminate any tiny air bubbles, ensuring none are left trapped in the substrate’s imperfection-filled gaps.
If thick coating by scraping is required, apply in layers (2–3 times), allowing each layer to surface-dry for 30 minutes (check by ensuring the surface is no longer sticky to the touch). Each application should not exceed 0.1 cm in thickness.
Grinding can only be performed once the putty has fully hardened. After applying and scraping, wait 60 minutes before sanding with #240 or higher grit sandpaper—dry sanding with a sander is recommended. During the rainy season or in high-humidity conditions, slightly extend the sanding time to ensure optimal results.
After applying the 4H coating, bake it at a high temperature of 200°C. Allow the oven to cool down until its internal temperature is nearly identical to the outdoor temperature before removing the coated item. This precaution prevents excessive temperature differences, which could lead to thermal expansion and contraction—causing issues like bubbling or cracking.

Important Notes

Store in a cool, dry place, away from heat and ignition sources, and protect from direct sunlight.
If bubbles seep in during application, use a scraper to smooth it out thoroughly, ensuring excellent adhesion.
If a thick coat is needed, apply multiple thin layers until the desired thickness is achieved.
Unused putty and hardener must be stored tightly sealed; putty mixed with hardener should not be returned to its original container.
Storage time: 6 months.
