getting adhesive off Lexan
 

I've got some old Lexan that still has the protective paper on it and last
weekend used a piece for a science project with my daughter.
The project, a simple solar oven, would have taken us about 1.5 hours to
build, but when I broke out a piece of the Lexan, I had the worst time
getting the adhesive off that was holding the protective paper. This took 3
hours, experimenting with soap, vinager, kroll oil, even acetone (small
scrape- ruined), and I finally gave up and used a window scraper which
ruined the surface. Worked ok for the oven, but wouldn't want my ports or
companionway boards to look like that!
I've had this stuff sitting around, waiting for a project, for more than 10
years in Florida heat and humidity.
I'd like to be able to use the rest and need advice on getting the
paper/adhesive off.
Thanks, MMC

I just cut a piece a few days ago that was even older (16 years), peeled
off the paper. It didn't want to come off easily, paper kept wanting to
tear...when it did I stopped and started working from another area.
Took maybe 5 minutes for a piece about 1 sq.ft. I'm in Florida too.

I use Goof Off adhesive remover. Works well and does not seem to haze the
plastic. Also a big believer in McGuire's Plastic Polish. Even use it on
my old Maui Jims.

Start at the bottom of the ladder of solvents and escalate 'til someone
wins.
My progression is:
Mineral spirits (aka paint thinner, tar & oil remover)
Toluene (AKA goof-off)
Lacquer thinner
Acetone
dynamite or nitric acid (joke)

This almost ranks as an FAQ on the aviation homebuilders lists and if
I had a real good memory I could say with authority many find success
using methel alcohol.

Plenty of options to try BEFORE I actually need to use this stuff again.
Never had any dynamite and I'm all out of C-4 so that option's a no-go.
Acetone instantly ruins the finish.
Thanks everyone.

Acetone instantly ruins the finish.
As will many of the 'tips' folks have suggested you 'try'.

This topic was covered a few months ago and the owner of Spectre Products
(who has been working Lexan for many years) posted "the best way to remove
the paper is with a heat gun".

So if you want to get the job done, use a heat gun. If you want to
experiment (and ruin the finish, make a mess, or start a fire) then use
chemicals.

Listen to bBob............
He has the right idea.

LEXAN CLEANING

The use of solvents which are not compatible with Lexan - polycarbonate
will result in the softening, crazing, and/or cracking of the plastic
part. This is especially true of polycarbonate lamps and mounting bases
which may be under stress in their normal applications. Polycarbonate
panels are resistant to some chemical and products non-resistant to
others. Resistance can be effected by the chemical concentration,
duration of exposure, degree of pressure and temperature at time of
contact.

SOLVENTS/CLEANERS COMPATIBLE WITH POLYCARBONATE:
Mild soap and water
Mineral Spirits
Mexane
VM and P Naphtha
Varsol No.2
#1 & #3 denatured alcohol

There is a product called Adhesive release that will help remove
covering. It is made by Seal. It is listed as "Unseal Adhesive
Releasing Solvent". It is made by Hunt Corporation, Statesville, NC
28677.

You could also check with a picture frame supplier. Most carry it.

If you can not find it send me an e-mail. I can get some for you.

Thanks Ron

Tried the heat gun-didn't work and warped the Lexan. The adhesive is a hard
solid after all these years.
If "owner of Spectre Products (who has been working Lexan for many years)"
had a piece of THIS Lexan he'd be looking for another option also.
I've been using chemicals, in one form or another, all my life and haven't
burnt anything down yet.

The can says that the active ingredient is Heptane. Then it says it
also contains benzene and toulene.

We use it on plex all the time. Great product. Go to any frame shop
and the can get you a can. Called adhesive release.
