About J-B Weld 37901 ExtremeHeat High Temperature Resistant Metallic Paste
Overall Feedback:
73% positive
68% praised for its exceptional bonding strength
The product has a strong adhesive power and can create a permanent bond. It is also non-flammable and has no solvents or VOCs.
66% appreciated the fast curing time, although 34% found it took too long
To ensure effectiveness, I recommend curing the product for at least 36-48 hours and applying multiple layers once the first layer begins to cure after 2 hours.
67% praised for its wide temperature tolerance
The temperature of the patch remained steady at about 170 degrees in one of the pictures, indicating good temperature tolerance of the industrial-adhesive-sealant-lubricant.
I have found that the product is a good alternative to torch welding and can resist high temperatures.
While applying the paste, the temperature of the patch remained steady at about 170 degrees.
67% liked the easy application process
I found the adhesive easy to mix and apply, and it dried and hardened exactly as instructed.
62% appreciated the minimal surface preparation required
I cleaned the surfaces with a wire brush until they were shiny and clean of residue.
After leaving the product in the sun for more than an hour, it becomes more liquid, making it easier to dispense and allowing for a smaller tip hole for more precise application.
