AW12 Green Wishbone Discs combine high-temperature green polyester film, silicone pressure-sensitive adhesive, and EPSI’s patented center pull-up tab to make circular masking easier to place, locate, and remove through demanding finishing processes.

Rated for temperatures up to 400°F, giving finishing operations a masking option designed for elevated-temperature coating and processing environments.
The integrated center tab gives operators a defined gripping point for faster placement and removal without searching for the edge of the masking disc.
The center tab is positioned away from the disc edge, helping eliminate the shadow effect associated with other tab designs while keeping the masking surface easy to handle.
The silicone adhesive system is designed for clean removal after processing with no shrinkage, helping protect the masked surface and reduce post-process cleanup.
AW12 uses a 2.0-mil green polyester carrier with a 1.5-mil silicone pressure-sensitive adhesive for a total thickness of 3.5 mils without the liner. The disc is laminated with a patented center tab and rotary die-cut on a specially formulated fluorosilicone liner.

A 2.0-mil green polyester carrier provides the masking surface for finishing processes reaching temperatures up to 400°F.
A 1.5-mil silicone pressure-sensitive adhesive helps the disc stay in place through the finishing process and remove cleanly afterward.
The patented center pull-up tab is easy to find even under thick coatings and provides a practical gripping point for placement and removal.
AW12 Green Wishbone Discs combine a green polyester carrier and silicone adhesive system with physical properties designed for industrial finishing environments.
3.5 mils without liner: 2.0-mil polyester carrier plus 1.5-mil silicone adhesive.
50 lbs/inch tensile strength with 110% elongation.
35 oz/inch peel adhesion with a silicone adhesive system and green polyester carrier.
Green Wishbone Discs are designed to protect defined circular areas while giving operators an easy-to-find center tab for accurate placement and efficient removal.

AW12 Green Wishbone Discs are widely used for general-purpose powder coating and wet spray masking. They can also be used for compatible e-coating, anodizing, and plating applications where circular surfaces must remain protected.
EPSI's Vendor Managed Inventory program can help finishing operations maintain appropriate stock levels for frequently used adhesive masking products while reducing the need for manual replenishment.
Disc diameter, surface condition, temperature, coating thickness, chemistry, and required masking tolerance can all affect product selection. EPSI can help evaluate your application and recommend the right masking approach.
