West System Vacuum Bagging 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 applications.
Any excess epoxy bleeds through perforations and is peeled from the cured laminate along with the fabric itself. It is also used in hand lay-up applications to allow more squeegee pressure and protect the lay-up from contamination.
West System release fabric peels easily and leaves a smooth textured surface, ready for bonding or finishing. It is not recommended for post-cure temperatures over 120 degrees F (49 degrees C).
