Fiberglass, RTV and plastic sources
Wed, 19 Feb 1997 10:02:32 -0500
Sometime ago I was given the following information as a source of
Alan Bond Fiberglass Products
221 Greencrest Ct.
Marietta, GA 30068-3825
At the time I was in need of fiberglass tubing for making insulating
sections for a vertical array. I found the tubing elsewhere, so I haven't
tried the above source.
For plastics (Lexan, Delrin, etc) try Cadillac Plastics:
For silicone RTV, I use the local Dow Corning dealer, Applied Technology
Corp. Check your area. My favorites are 732 standard clear silicone
adheasive(about $3/80z tube: like bathtub caulk) and 734 clear flowable
silicone adheasive (about $8/8oz tube: flows like molassas, fills hard to
reach places, excellent for potting baluns, exposed connectors, etc. cures
like regular RTV). Dow also has types designed for electrical service. Try
here for info.
Hope this info helps.
