Vacuum bagging is a clamping system used for laminating a wide range of fabrics, core materials and veneers. It offers many advantages over conventional clamping. For repairs and composite construction, it uses atmospheric pressure to deliver firm even clamping pressure over the entire surface area, regardless of the type or quantity of material being laminated. By laminating over simple molds, composites can be molded into a wide range of functional shapes.

879 Release Fabric

Economical Release Fabric is a tough, finely woven nylon fabric treated with a release agent. It is used to separate the absorber, breather and vacuum bag from the laminate in vacuum bagging operations. Excess epoxy bleeds through and is peeled from the cured laminate along with the Release Fabric. It's also used in hand lay-up applications to allow more squeegee pressure and protect the lay-up from contamination. Peels easily and leaves a smooth textured surface, ready for bonding or finishing. Not recommended for post-cure temperatures over 120°F (49°C). Available in 60" wide x 2 yd., and 10 yd. rolls; also in 60" x 9" sheets.

881 Breather Fabric

Breather Fabric is a lightweight, polyester blanket that provides excellent air passage within the vacuum envelope while it absorbs excess epoxy. Available in 45" wide x 2.7 yd., and 10 yd. rolls.

882 Vacuum Bag Film

Clear, heat-stabilized, modified nylon resin film. Can be used at temperatures up to 350°F (176°C) for typical composite cure cycle times. A tough, stretchable film for high vacuum pressures. Available in 60" wide x 2 yd., and 20 yd. rolls.

883 Vacuum Bag Sealant

Mastic tape sealant for airtight seals between vacuum bags and molds. Easy to work around difficult angles, patching small leaks in the vacuum system. Available in 1/2" wide x 25' roll.
