This is not on topic except for the fact that the product we are talking about uses this as it’s main solvent and we use this stuff to seal antennas. If it’s dangerous everybody needs to know it. Moderators, if it’s too far off topic lets us know please. Reference: http://en.wikipedia.org/wiki/Methyl_ethyl_ketone Paul Butanone is a manufactured organic chemical. It is a colorless liquid with a sharp, sweet odor. It is a ketone, also known as methyl ethyl ketone (MEK). Butanone is produced in large quantities. Nearly half of it is used in paints and other coatings because it will quickly evaporate. It dissolves many substances and is used as a solvent in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films. It is also used in the synthetic rubber industry, It is used in manufacturing plastics, textiles, in the production of paraffin wax, and in household products such as lacquer, varnishes, paint remover, a denaturing agent for denatured alcohol, glues and as a cleaning agent. It is used for synthesis of methyl ethyl ketone peroxide, a catalyst for some polymerization reactions. It is highly flammable. It is not considered a large health threat. Butanone occurs as a natural product. It is made by some trees and found in some fruits and vegetables in small amounts. It is also released to the air from car and truck exhausts. [edit] Health effects The known health effects to people from exposure to butanone are irritation of the nose, throat, skin, and eyes. There are no known cases of any humans dying from breathing butanone alone. However, if butanone is breathed along with other chemicals that damage health, it can increase the amount of damage that occurs. Serious health effects in animals have been seen only at very high levels. When breathed, these effects included birth defects (Schwetz et al. 1991. Fund. Appl. Toxicol. 16:742-748), loss of consciousness, and death. When swallowed, rats had nervous system effects including drooping eyelids and uncoordinated muscle movements. There was no damage to the ability to reproduce. Mice who breathed low levels for a short time showed temporary behavioral effects. Mild kidney damage was seen in animals that drank water with low levels of butanone for a short time. There are no long-term studies with animals either breathing or drinking butanone. ------------------------------------------------------------------------------ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of v44kai Sent: Wednesday, January 09, 2008 7:45 AM To: [email protected] Subject: Re: [Repeater-Builder] Re: Scotchkoat Hi Tim, What is MEK, I do not know that product, or what it stands for (MEK) but your experience is very interesting and encouraging. v44kai.....Joel. ----- Original Message ----- From: Tim and Janet To: [email protected] Sent: Wednesday, January 09, 2008 7:25 AM Subject: [Repeater-Builder] Re: Scotchkoat Please believe and listen to these warnings. 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.

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.
