Tacky Tape® SM5143 is a sealant tape developed for use in composite vacuum bagging. The tape was specifically developed for use in turbine blade manufacturing. This product has been formulated to outperform all tapes in its class. Initial tack is great and it will maintain an air-tight seal during the cure cycle and then strip clean from the mold during de-bagging. This tape has an optimum cure temperature range of room temperature to 425°F (218°C).
