Vacuum Bag Sealant Tapes This product is used to seal the nylon film vacuum bag to itself, forming a leak proof, and vacuum tight seal. It consists of high temperature extruded mastic (Fig 3). When vacuum bagging with sheet film, it is likely that there may be some excess film on the top surface once the bag has been folded over the glass. This requires the use of extra sealant tape, sealing the excess film on the top surface, thus creating a pleat. Sealed pleats can be seen in Fig 9-10. It is imperative that the sealant tape extends to the very top of the pleat.

SM5142 operates at higher temperatures and exhibits lower levels of tack. Both are designed for use in this application. Vacuum Hardware To apply vacuum to the bag, a range of vacuum connectors is required. This is a very simple range of products which offer excellent heat resistance, durability and vacuum integrity. Products available include: • Vacuum breach unit 2 part • Vacuum gauge fitted with non-return socket • Brass non return male plug • High temp silicone rubber hose • Brass non return female socket Vacuum gauge Our products have a standard 6mm (0.25in) BSP thread and 50mm (2in) or 75mm (3in) diameter. Our vacuum hoses can be pre-fitted with non-return couplings and 90 degree elbows, T pieces, etc. Repair instructions are available on request. Vacuum Couplings Our double shut off plug and socket units are fitted with high temperature Viton seals (Fig 7). Typically the male plug is bonded to the upper part of the vacuum breach unit (Fig 4). The female part is attached to the vacuum hose (Fig 5-6). Once connected, vacuum can be applied. The valves can be quickly and easily disconnected without loss of vacuum to allow the finished lay up to be moved to the oven or autoclave. Figure 3. Sealant tape attached to the vacuum film. Release paper should be left in place until ready to complete the bagging process. Note that the lower part of the vacuum breach unit must be positioned prior to sealing the bag together. Figures 4-7. Show two part vacuum breach unit (with 50mm (2 in) base plate), vacuum hose end and socket assembled, vacuum hose with threaded end only and finally brass plug and socket units.
