RE: [Repeater-Builder] Re: Scotchkoat
One method with Scotchkoat, which we used in the Gulf of Mexico platforms cabling. Wrap a good Scotch tape over the cable and connectors tightly extending the wrap 2 to 3 inches over the cable jacket on each side. Then scotchcoat the tape wrap a small portion of the cable covering. Then tape wrap the whole assembly again with a good tape. Now when you want to remove the scotchcoat you just cut a slit the length of the tape wrap and peel off the tape and scotchcoat together. This has worked great in salt water environments for many years.

To make removal easier: Bake above 600°F/316°C for several hours or above 800°F/427°C for one hour prior to sandblasting. OR Heat coated part to 250°F/121°C or above and scrape coating off. Other removal methods include the use of epoxy strippers and hot sand baths. = = = = = Neither method would work to get it off your hand. In the meantime, don't get any in places you don't want it!

Re: [Repeater-Builder] Re: Scotchkoat
Hi Paul, thank you for this info, based on this I'm sure it's in the auto car paint thinner, which I used a lot for cleaning stuff without a respirator, and cloves hi hi, I know that stuff could give you I high. Will do some research on the chemical we use here and try very hard to use protection when using them. v44kai.Joel. - Original Message - From: Paul Finch To: Repeater-Builder@yahoogroups.com Sent: Wednesday, January 09, 2008 10:24 AM Subject: RE: [Repeater-Builder] Re: Scotchkoat Joel, It’s name is Methyl Ethel Ketone or MEK for short. It is what makes some glues dry fast and it’s also what kids get high on when the sniff glue. Most spray paint cans have it to help the paint dry faster. It is dangerous stuff.

Several years ago I decided to go back to the gym and get back into shape. I went to the doctor for a physical which included a blood test. As part of the test they look at two liver enzymes. One of mine was high just outside the normal range. The doctor said to come back in a month to retest. The next month the first enzyme went higher and the other one went off the scale. I had a liver ultrasound which came back normal. He then ordered a liver Biopsy. Not a pleasant experience!!! The biopsy came back almost normal other than signs of age and a body that had been neglected. Each blood test after this my enzymes started coming back into range. When I (we) tried to figure out what had happened the only thing that we could link it to was MEK. I had just finished building a small experimental airplane that is made up of aluminum tubing and fabric. All of the aluminum was cleaned with MEK and the glue contained MEK and was thinned with additional MEK. All of this work was done with large opening doors and most of the time had a fan running. Most of the time I did not use gloves. The facility I work in has MEK banned. Not due to my experience but because of environmental concerns. MEK is great stuff like a lot of other chemicals that we take for granted. Please use them in accordance with all warnings. By the way MEK is still available by the gallon at Home Depot and Lowes locally. I now ventilate the room wear gloves and a respirator when using this product. I apologize for the long email but wanted to warn those that may expose themselves to chemicals.

I have a buddy who lost his leg to cancer and they traced it back to a solvent he used as a jet engine mechanic in the Air Force. He managed to live through it, but minus a leg. They proved beyond a doubt that it was the solvent that caused the cancer. Sorry I don't remember just which solvent it was - 73 - Jim W5ZIT Back to top Reply to sender | Reply to group | Reply via web post Messages in this topic (21) 2h. Re: Scotchkoat Posted by: Mike Besemer (WM4B) [EMAIL PROTECTED] mwbesemer2000 Tue Jan 8, 2008 2:52 pm (PST) More than likely the solvent in question was carbontetrachloride. That's what was used prior to my AF time (starting in 1981), when we used PD-680. We also had trichlorethaline and MEK. Regardless of the solvent in question, if you like your liver (and other various parts), you'll wear the appropriate protective gear, avoid the fumes and use it properly. Nasty, nasty stuff. all of them. de WM4B Mike Kathleen, GA No virus found in this incoming message. Checked by AVG Free Edition.

To members of the fire service it falls into the classification of Methyl Ethyl Badstuff. Just be careful with it
