What glue seems to work best for gluing a plastic (polycarbonate I
think) emblem permanently and securely onto dacron cloth? I think the
dacron is coated so that might make a difference.

Joe,

I am going to suggest that you contact PolyFiber for a correct answer. A
problem is that most glues do not stick to polyester fabric. In fact
polyester fabric is used in many bonding environments as a peel ply to
prevent sticking. I have used some glues that stick to polyester but
there are pretty harsh and may actually damage the fibers.

The coatings used on polyester actually penetrate between the weave of
the cloth, wrapping around the threads and filaments. It is considered a
mechanical bond. Coating the fabric first with dope or PolyFiber should
greatly improve the bond of the emblem to the fabric.

The best glues that work on polycarbonate usually bite into the plastic.
I don't know what will bind the polycarb to the and work well with a
base coat on the fabric.

In many cases I have found that an adhesive film, sort of a double sided
tape that leaves a very thin layer of adhesive...similar to the stickum
on duct tape, has worked well to stick two slick surfaced plastics...but
is not intended for a fabric. Coat the fabric first with the accepted
base coat.

I know you said "permenant", but try velcro. Stitch onto the fabric,
and attach the plastic with adhesive.

For this perticular job, I'd try a spray-on adhesive like Scotch 77,
or the craft shop equivelant.

The directions recommend coating both parts, which could
get messy spraying on an airplane (or any other outside surface?.

Mask off the surface to match the shape of the art work.

Spray adhasive on both pieces (ie: follow directions BEFORE
all else fails?)

Polytack might work. It's made to stick to poyester fabric. You might need
to get down to the bare fabric so the glue can penetrate the weave though.
Go for a mechanical bond vs. a chemical bond.

Joe,

I have had GREAT luck with 3M's F9460PC adhesive transfer tape.

it is light and STRONG.

There was an article in KiteLines a few years back about it.

Hi Joe , hi folks.

If your emblem can be drilled, you can just drill very small holes at
the edge (3 or 4 shall do).

Then, using sewing thread, attach (sew) to the dacron.

Just an idea.

I think you need to be sure what the plastic is, and what sort of
dope is used on the Dacron. It is very easy to get incompatable
materials and permanant damage.

Hi Joe
Lots of choices, but here is another one! :-)
I have used this glue successfully dozens of times to fix the leading edge
tubes of inflatable kite surfing kites, the tubes are made of coated dacron.
The glue is clear, flexible, polyurethane, many parts of modern cars are
stuck together with this stuff!
I buy it in small tubes at camping stores it is sold as "seam" seal.
It can be bought in large tubes from automotive and building suppliers.

This is all good advice, thanks! I'll try some of these and run some
quicky tests to see what works.
