PEF-10 Polyethylene Film (PE) is our new, recommended Patent Pending application process for AquaBond® underwater repair products. Applying the adhesive or sealant to the polyethylene film above water, then taking that strip of film underwater, allows you to precisely land the material exactly where you need it – and spread it smoothly on and around contours. Once the adhesive has cured, the film peels off leaving a super smooth, finished repair! For more product details and applications, visit Polyethylene Film page.
