Features
• Medium-tack adhesive which will not lift during forming to help save money on
reworks.
• Acrylic adhesive is non-corrosive, non-staining with stable performance and clean
removal to help reduce labor costs.
• Heat resistance to withstand temperatures up to 160°F (71°C), approximately 30°F
higher than conventional 3-mil LDPE tapes to help reduce reworks.
• Enhanced conformabiltiy to products which are subjected to severe forming or
fabrication to help reduce reworks.
• Increased break strength for easier removability without tearing or slivering to
help reduce labor costs.
