The specific job Blister-Free 600 is built for
Madico Blister-Free 600 is a special-purpose film for glazing with one specific job to do. Bus shelters, transit panels, kiosks and school glazing made of polycarbonate or acrylic collect scratches, marker tags and etching that cannot be polished out. New panels are a costly fix. Standard films blister on plastic, because the plastic takes in and gives off moisture.
What Blister-Free 600 does, in Madico's figures
Blister-Free 600 is a clear film built from three plies of 2 mil polyester with a silicone pressure-sensitive adhesive that Madico says is unaffected by moisture moving in and out of plastic. Madico describes the film as a sacrificial layer against graffiti, scratches and acid etching that helps hold fragments together if the panel breaks. The spec sheet lists a break strength of at least 150 pounds per inch.
Where Blister-Free 600 fits best
NorthGuard suggests Madico Blister-Free 600 for jobs like these.
- Polycarbonate (Lexan) and acrylic (Plexiglas) bus shelters and transit panels.
- Kiosks, ATM machines, vending machines and information displays.
- School and street-level plastic glazing that gets tagged or scratched.
- Plastic panels where Madico presents a replaceable film as a cost-effective alternative to new panels.
What Blister-Free 600 will not do
Madico Blister-Free 600 has limits that NorthGuard states before any quote.
- Blister-Free 600 is made for uncoated polycarbonate and acrylic; ordinary glass takes a different film.
- Madico's published optical and UV figures for Blister-Free 600 do not agree with each other, so this page prints none of them.
- The film takes the damage instead of the panel, so a tagged or etched film has to be replaced.

Blister-Free 600 questions and answers
NorthGuard answers these questions about Madico Blister-Free 600 with Madico's published data.
How is Blister-Free 600 different from Blister-Free 200?
Blister-Free 600 is a three-ply film that Madico positions mainly as a sacrificial layer against graffiti on plastic, while Blister-Free 200 is a thin clear base layer for other films. Both use a silicone adhesive made for plastic glazing, and Madico's Blister-Free 600 page also mentions pairing it with solar control and safety films.
Why does this page give no UV figure for Blister-Free 600?
Madico's UV figures for Blister-Free 600 conflict between its product page and its spec sheet, so NorthGuard prints none of them. Madico presents the film mainly as a sacrificial layer against graffiti, scratches and acid etching.
Will Blister-Free 600 blister on polycarbonate?
Blister-Free 600 is designed to avoid the blistering that standard films show on polycarbonate: Madico says its adhesive is not affected by the moisture that plastic takes in and releases. That moisture cycle is what makes standard films blister on plastic.
What happens when vandals mark Blister-Free 600?
Vandal damage lands on Blister-Free 600 instead of the panel, and the marked film is then replaced. Madico says the film is easy to install and replace and describes it as a cost-effective alternative to replacing damaged plastic glazing.
How strong is Blister-Free 600?
Madico's spec sheet lists Blister-Free 600 at a tensile strength of 25,000 PSI, a break strength of at least 150 pounds per inch and a peel strength of at least 2 pounds per inch. The build is three plies of 2 mil polyester laminated with a clear acrylic adhesive.
