UV Masking Materials for Sandblasting and Shot Peening

Temporary UV masking materials for sandblasting, dry media blasting, and shot peening need to withstand high velocity impact of organic media, aluminum oxide, cut wire, glass beads, and steel shot. When properly applied and cured with UV light, Panacol UV Masks provide consistent and reliable protection. Their resiliency and strong adhesion prevents edge lift, which preserves the integrity of the surface being protected.

All Panacol UV masks for dry media blasting are designed to be removed by peeling. The peeling process can be accelerated by incorporating a quick hot water dip/rinse prior to peel. Hot air may also be used if practical.  Elevating the temperature of these masks causes them to become more elastic and easier to remove. Multiple viscosities of each product are available to accommodate various dispense methods, which can include dip, spray, or manual application from syringes. Panacol UV masks are available with a color additive to provide appropriate surface contrast for better visibility of coverage during dispensing and removal.

Please view the masking materials listed below for a possible candidate for your sandblasting, gritblasting, or peening process.  Please contact Panacol-USA to confirm your product selection and to secure additional application assistance, including samples and curing process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Panacol-USA will investigate other solutions that include development of masking materials specifically tailored to the complexity of your application.

Panacol UV masking material provides surface protection during grit blasting.
