Vacuum bag sealant tapes

Vacuum bag sealants, also known as sealant tapes or tacky tape, seal the bag perimeter during infusion and vacuum consolidation. Their role is to seal the assembly, not fill or repair the composite part.

What to consider when choosing

Sealing the vacuum assembly

Sealing the bag onto the mould

Selection must account for the film, mould surface and curing process. The range includes references for different working conditions and for metal or composite moulds, depending on the product.

Joints and removal after processing

Besides perimeter sealing, some sealants are intended to join films or seal assembly joints. Adhesion during work and subsequent removal are different criteria: consult the reference's instructions for the intended surface and demoulding temperature.

Completing the vacuum assembly

Select the tape together with the vacuum bags and other vacuum materials for composites. Changing film or curing cycle also requires reviewing the sealing system.
