My question is about the type of adhesives that are being used out in the
field.
> Our practice requires us to attend many different clinic settings
throughout the community. Frequently our work space is an unused patient
room, utility area or, in some cases, a storeroom. None of these areas have
as adequate a ventilation system as in our home office. As you can imagine,
the vapors given off by the adhesive we use to glue various forms to polypro
can be somewhat overpowering to us and others. Primarily we are using
Poly-Adhesive purchased from Cascade Orthopedic Supply.
> Questions: What adhesive are you using that are less polluting in a small
working environment? If they are better are they as effective in regards to
drying time, stability, etc.? In the past we've used adhesive film but we've
found that the pads can migrate when used in an area of shear.

try 3-M spray
>adhesive. The 77 strength sucks, so don't even bother with it. The 90
>strength is some good stuff though.
77 spray adhesive is meant to be used with heat activation, not a moist
tack. When it is heat activated it is agressive and durable, bonding to
most surfaces that are not oily or wet.

Have you tried a sheet of self-adhesive aliplast available from Cascade andSPS. The idea for carpet tape(which is double-sided and very strong) is excellent
---------------
I have one more suggestion for you. 3M has a line of bonding tapes under their
Scotch brand. These are adhesive films that are laid on like a tape, but are just
adhesive. The psa is rolled with a release liner. It is used like double sided
tape, but without the usual core.
3M has a booklet called Designer's Reference Guide to High-Performance Bonding
Tapes for Product Design and Assembly. The local 3M office is 6023 S. Garfield
Ave, LA 90054, (213) 726-6300.
The guide in my file is a couple of years old, so the area code might have
changed. The national number is (800) 227-5085 ext 9.

In reference to your adhesive inquiry and problem of foam pads moving due to friction / shear. I have had a number of field reports from folks using Tamarack's ShearBan to overlay foam pads. The pressure sensitive adhesive on the back of ShearBan anchors the foam pads in place. The Teflon surface of ShearBan minimizes the shear forces. Dan Snelson over at Shriner's has been using this technique.
I also have a report from Tom Gavin regarding the use of ShearBan in spinal orthosis for idio scoli. He has been able to increase the amount of correction due to the ability to increase pressure of the lumbar pad. The Teflon again reduces skin shear, thus he is able to use a higher corrective force without an increase in patient discomfort.
