Fiberglass Fabric Tapes

Boat, Tooling and Reinforcement Tapes Manufactured to Your Specs

Mutual removes the lubricating sizing applied to fiberglass yarns so that they can become compatible with most thermosetting resins. This removal process is done by baking the cloth and removing the sizes through burn-off.  Many types of chemical finishes are applied by Mutual after heat treatment. Chemicals used by Mutual in processing fiberglass fabrics are designed to be compatible with thermosetting resins.  This serves to vastly improve resin bonding by chemical bridging.

At Mutual the finishing and processing operations, including the application and control of chemicals, is conducted under strict quality control standards.  Finishes applied at Mutual Industries include, but are not limited to: Silane Monomer, Silane epoxy, Synthetic Resin Weave Set , Volan, High Carbon Chain Polymer Coupling Agent.

Fiberglass boat, tooling and structural reinforcement tapes are used primarily for “wet lay-up”  applications.  To optimize the tape’s weetability and cure time characteristics, Mutual fiberglass tapes are manufactured with a fairly open weave. To insure maximum compatibility between the glass and resin, Mutual uses advanced state-of-the art heat cleaning and finishing equipment.
