Our take on the Yellow Sealant Tape

Yellow Sealant Tape AT200Y is a high-tack vacuum bagging tape for composite and resin work. It bonds bagging film to aluminum, steel, nickel, graphite and fiberglass tooling and holds up to 400°F cure cycles. The aggressive tack keeps film from shifting or leaking under vacuum, but it is hard to reposition once pressed down. Compared with lower-tack tapes such as gray sealant tape, it trades adjustability for a stronger hold.

About the Yellow Sealant Tape

Yellow Sealant Tape AT200Y seals vacuum bags to tooling surfaces. It works on aluminum, steel, nickel, graphite, and fiberglass.

The tape has aggressive tack. This extra tack makes bagging film less likely to shift or spring leaks under vacuum. It also makes the tape much harder to reposition once it is in place, so use caution when positioning.

It is suitable for curing cycles up to 400°F and strips cleanly from molds once the process is complete.

Questions and answers

What is yellow sealant tape used for?
It seals vacuum bagging film to tooling surfaces during composite layups and resin work. It holds the film tight so the bag does not shift or leak under vacuum.
How is it different from gray sealant tape?
Yellow AT200Y has extra tack for a stronger hold. Gray sealant tape is the better pick when you need to reposition the film or want less aggressive adhesion.
What surfaces does it stick to?
It bonds to aluminum, steel, nickel, graphite and fiberglass tooling. The aggressive tack suits smooth metal and composite molds.
Can it handle high-temperature cures?
Yes, it is rated for curing cycles up to 400°F. It also strips cleanly from the mold once the cycle is done.
Can I reposition the tape after pressing it down?
Not easily. The extra tack makes repositioning much harder, so position the film carefully before pressing the tape into place.
What are the tape dimensions?
Each roll is ½ inch wide, 1/8 inch thick and 25 feet long.
