Sealant Tape is typically used whenever an air tight seal is required and will adhere to most surfaces. It is most commonly used in the composite manufacturing process of temporary as well as permanent vacuum bagging.
Release film ensures that breather fabric or flow mesh does not bond to the curing resin. By use of various perforation patterns, the amount of resin that is bled out of the laminate can be controlled, to achieve the correct fiber ratio within the composite.
