TC760X

TC760

Trelleborg TC760X is a medium temperature, low density syntactic epoxy tooling board designed to act as a more durable/higher temperature master molding base or facilitate direct-to-part tooling.

 TC760X is a superior quality tooling board, offering crack resistance and dust free machining.

Excellent dimensional stability

Maintains its shape at elevated temperatures, increased durability, no cracking, reduced edge chipping in machining

Operation temperature up to 130°C

Direct-to-part tooling with standard 120 °C prepregs

Improved part/tool surface quality

Reduced rework on molded component surfaces due to superior tool surface quality

Quick mold preparation

Reducing surface preparation time prior to sealing/Reduced sealant usage as compared to standard epoxy boards

Key Applications

Master models, part tooling

Lay-up tools for low and medium temperature epoxy prepregs

Product sizes

TC760X is available in a standard board size of  24” x 60” at the following thickness: 2”, 3”, 4” and 6”

Cutting

TC760X can be sawn using carbide or diamond coated saw blades or cutting wheels

Bonding

Large patterns can be constructed from boards using the appropriately selected epoxy adhesive system. Trelleborg adhesive system 551A/B is recommended. The adhesive system must offer adequate pot life and be capable of meeting the mechanical and thermal properties of the tooling board.
