RTV Silicone And Coax Outer Jacket: Safe ?

We use several grades of electronics RTVs at work in contact with coaxial cable jackets and all kinds of components to meet DO-160E vibration requirements for airplave use. The stuff we use does not have the characteristic acetic acid smell which I think is actually stearic acid. According to the labels I've read, much of the consumer-grade RTV does in fact release acetic acid as it cures. Not good stuff to use around electronics or other metals. The noncorrosive, "moisture cure" or "neutral cure" RTVs are a better choice for use around electronics. The ones marketed as "electronics- grade" are the surest bet in this regard, and usually need to be mail-ordered. A possible compromise would be the consumer-grade RTVs which are specifically advertised as being noncorrosive for use on metals - the labels on these say that they release methanol and ammonia during cure. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

If it won't harm fish, it surely won't harm your hardware. 73, Bill W6WRT |
