## Description

Hy-Poxy H-450 Alumbond 6.5 oz Aluminum Putty Repair Kit : desertcart.in: Office Products

Review: Sealed up Boiler leak - I have an aluminum heat exchanger in my home heating boiler (Utica UB90). I drain the system and refill every year to maintain proper PH. The boiler developed a leak at the bottom of the heat exchanger, looks like the gasket material between the two plates failed. The boiler is 16 years old which is right at the life of an aluminum heat exchanger so I attempted to patch the leak. Tried JB Weld, 2-3 variations, with no luck. Use Permatex which held for 3 months, then I found this product. I got the boiler up to temp so the heat exchanger was hot. Cleaned the surface, roughed it up with a wire wheel, mixed the compounds as instructed, and applied to the leak. Let the boiler completely cool and as it did, I noticed the compound was pulled into the seam, so mixed a little more and applied. You have 45 minutes working time before the material gets too hard to spread, hardens at 1 hour and fully cured in 4-5 hours. Four hours later I fired the boiler, leak was sealed, and I am going on 1.5 years with no issues. This is a problem solver which saved be roughly $3,000.

### ⭐⭐⭐⭐⭐ Did what it was supposed to do.
*by J***A on 4 April 2021*

I bought this product after JB let me down. I had a cracked door frame on my RZR. When I say cracked i mean completely separated Look, I’m not an exact measurement kind of guy when it comes to this stuff. I squeezed what looked like equal portions onto a piece of cardboard. Found a clean broken piece of trim . Mixed up the solution for maybe a minute. Directions say 3. The epoxy is a little runny but not that bad. If you needed it to flow into a space it would with the help of gravity. It’s not going to pour like oil. I then put it on the cracked area with the broken stick. Smeared it around cover the crack and other area. Kept the kids away for a bit and 3 hrs later I checked it. Some of the solution flowed into the cracks and you could see a partial outline. 5 hours later I mixed up more in the same order and speared it on. Let sit over night. This morning went out there, checked the area. Dried solid. I opened the door and slammed it 10 times in a row. The solution did not crack and the door was holding up good. I’ll report back if it breaks.
