I removed one of those Heat Shield material wraps that goes together with Velcro. The ends were all ratty and loose. I bought some new material of the same design to replace it. I read about a trick for keeping the ends from unraveling: Liquid Electrical Tape. Paint it on where you are going to cut it on both sides and before and after the cut line. In other words make it wider where you are going to cut it. Let it dry over night. When you cut it (sissors) the threads says put!
I looked at the Permatex SDS information. It's some seriously bad stuff: https://www.permatex.com/wp-content/uploads/sds/85120.pdf Don't use it unless in a well ventilated spark free area. Xylene and MEK. Super flammable as a liquid, unclear about dry, but I would test before installing it in a hot location...
Max this product information is identical to Permatex. Look at its temperature Service range in bold below. Vet The Star brite liquid electrical Tape is quickly considered the best electrical industry. It is used in a lot of advanced home and commercial applications. Some of them are Laptop power cords, outdoor exposed wiring, USB cables, sprinkler pumps, etc. The Star Brite tape did not peel off or crack when I used it. I like it because it remains flexible after curing for a long duration. Another important thing is that it is superior in quality and made of a vinyl base instead of rubber. Due to that, this is the best liquid insulation for wiring to provide a secure, long-lasting, and reliable dielectric seal. Overall, the Star Brite 4-Oz Liquid Electrical Tape is a reliable and effective product often used for electrical repairs and projects. Its main features are easy to apply, dries quickly, is durable, and is a long-lasting electrical tape for outdoor use. Highlighted Features It is a waterproof, UV-resistant, dielectric coating. It remains flexible after curing. Service range -50°F to +275°F Stops terminal screws from loosening due to vibration. Multicolors allow the coding of wires. Pros: Insulation and protection. Easy application. Non-conductive and non-drying formula. Cons: May require multiple coats.
Nice, I guess 275F is good enough if you are insulating fuel lines above the intake, but might not be if you are close to the exhaust pipes... The Permatex product is Vinyl also, maybe the same stuff?
As a follow-up - I painted a cotton sock with the stuff and let it sit overnight. Then I heated it to 300 F on the stove and used a thermo gun. The insulator smoked a bit and the sock started to brown. The liquid tape did not burn off or degrade. I next painted some aluminium foil and let it sit overnight. Again I heated it up and the insulation smoked. At 500 F I stopped. It pulled up a bit from the foil in one small area, but did not fail. I suspect it is difficult to adhere to the foil. It both cases it still stuck to the material (except the foil) and remained flexible and black. These were quick tests (the wife was aware...) so it might make a difference over several hours. I don't really care if it fails as long as the threads do not unravel. The shield is covering one of the AMP rear oil balance lines. One end will be at the oil pump and the other tucked in to the bell housing. The liquid tape is just cosmetic. So in hindsight maybe a silicone gasket maker would work better if it would soak into the fibers and hold them in place. I'll try some - next time.
Most companies have a safety margin built into on their specs. I looked up this product (another with same chemistry). It said good for 278 degrees F. I would say, you are good for 500F with the built-in safety margin. I'm surprised the aluminum foil didn't melt. Most soft aluminum melt at 300F or a little above. VET
No it doesn't. You wouldn't be able to use it in the oven if it did! Aluminum's melting point is 1,221°F Thanks for testing and sharing this!
Yes, you are correct. What I should have say, it depends on the aluminum alloy. They defer a lot on temperature ranges. Sorry VET
Another point 12lives, I have to check my kitchen oven, but I think it only goes to maybe 500*F max and maybe not that high. I can see crispy cup cakes at anything higher than 350F, LOL.
Ops, fat fingers hit post reply. I love metal science. Pure aluminum has a melting point of 1220°F (660°C), but aluminum foil can be used safely in the oven at up to 400°F (200°C) and for direct-heat grilling. When choosing aluminum foil for baking, look for foil that's labeled as oven-safe or heat-resistant, which can withstand higher temperatures. Interesting info. Hope any of this helps. VET
I did it on the stove top, on a burner. Quick and easy, and I could watch it. I used a thermo gun to check the temp. Note - Aluminum Foil is Food SAFE to use to 400 - 450 means it will not transfer into the food. It will actually go to 1220 before it melts.
Great news, seems to be a great way to test the material and sealer. Used a temp gun, great idea! I just bought one a few months ago when working on a high temp radiator water/coolant issue. I love this temp gun. Should have bought one a few years ago. Vet
