TC-1604 A/B is a filled, easy to apply, laminating epoxy resin for variety of fabricating applications.Designed to be used with heavier weight fiberglass cloth (typically 8-10 oz. tooling fabric), TC-1604 can produce thick laminates without excess draining of the resin. Being a very stable system with low shrinkage, its common usages include:

- Drill and Trim Fixtures
- Pattern/Foundry Applications
- Composite Tooling
- Support Shells for Silicone Glove Molds.

It features the ability to cure at room temperature for applications that do not require a working service temperature above 224°F (107°C). TC-1604 can also be used as an adhesive for bonding wood, composites, and other materials. Adding fillers like fumed silica, micro-spheres, and short-strand fibers can create pastes for fillets, fairings, and bonding applications.
