TRELLEBORG APPLIED TECHNOLOGIES
As part of its ongoing commitment to supporting
the environment, Trelleborg’s latest tooling board
the TC760X provides a dust free machining
experience reducing airborne particles and
environmental impact, and improving production
efciency.
Traditional manufacturing of tooling boards for
creation of durable, reusable tools, prototypes and
models can cause a large amount of dust to build
up, increasing machine downtime and creating
additional environmental concerns.
Applications:
The TC760X can be used for the following:
• Master models and direct to part tooling.
• Lay-up tools for low and medium temperature
curing epoxy prepregs.

TC760X
Features & Benets:
TC760X is a premium quality tooling board offering
a wide range of benets:
• Dust free machining
Excess product comes off in large akes rather
than dust, signicantly reducing residue on
machinery.
• A-class surface nish
Can be machined to a high-quality surface that
requires virtually no secondary nishing or
polishing before use.
• Suitable for operation temperature use up to
135°C *
Ensures good compatibility with intermediate
temperature curing prepreg.
• Excellent toughness and durability
Maintains its shape at elevated temperatures
with minimal edge chipping.
• Consistent, reliable performance
Tools are durable and tough, multiple nished
parts can be made direct from the tooling .
• Easy to seal
Requires up to just 4 coats.

Storage
The board should be stored in a dry warehouse.
Health & Safety
Eye protection and a face mask should be worn
when working with Trelleborg TC760X.
Please refer to the Trelleborg MSDS.
Cutting Guidelines
TC760X can be sawn using carbide or diamond
coated saw blades or cutting wheels.
Bonding Guidelines
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.
To ensure good bonding:
• The adhesive should be applied to both surfaces
(dust free) using a notched spatula.
• The surfaces should be brought together and a
uniform clamping pressure applied by either
mechanical or vacuum means.
• Any surplus adhesive that extrudes from bond
lines after curing can be machined off.
• Bonded joints should be left to cure for 24 hours
at ambient temperature for best results.
The recommended adhesive has matched
characteristics to the TC760X material.
Machining Advisory
In order to avoid board distortion, it is
recommended that stock removal should be taken
equally from opposing faces. Where this is not
possible, then the board should be supported by
and bonded to additional layers.
To minimize distortion when machining large at
boards, it is advisable to rough cut one face, invert
the board and machine the rear face, re-invert and
complete the machining. The board can be nished
by the use of successively ner grades of wet and
dry abrasive paper.
