Remove the protective film from the light guide.
1Mark the light guide at the required length, adding
0.5 in. (13mm) for every 16 in. (406mm) to account
for shrinkage during the forming process.
2
Cut the light guide to the required length using a
hacksaw, chop saw (cross cut or veneer blade only),
band saw, or other appropriate plastic cutting tool.
Take the proper safety precautions when cutting the
light guide.
3Fill the entire light guide channel with the Silicone
Bend-Aid(s) (GEXNBA) and press into place. Bend-Aid
must be installed prior to heating and forming.
NOTE: The Silicone Bend-Aid (GEXNBA) is reusable.

Heating and Forming
Step 2:
Part 1: Move the section back and
forth while rotating about the
diameter until it is soft and pliable.
Gently bend to the desired angle.
NOTE: It is recommended to use a
heat-deflecting shield to distribute
the heat evenly.
NOTE: Avoid localized overheating
that may result in distortion or
damage (i.e. bubbling) of the light
guide.
For large bends, use either an industrial oven or heating blanket.
For small bends, use a heat gun.
Part 2: The workable forming time is
about 2–3 minutes. The light guide
must remain in the desired position
until completely cooled. See the chart
above for minimum bend radius
guidelines.
Allow the light guide to cool by natural convection or lightly forced cool air (i.e. fan). Remove the Bend-Aids for reuse only
after the light guide has completely cooled In order to remove any minor surface flaws, perform a light sanding using
400 grit sandpaper. Flared or deformed ends can be trimmed. The light guide is now ready for light engine installation.
Heat gun
Preheat the heating equipment to
300°F (149°C). Heat light guides
approximately 6-15 minutes until
soft and pliable. Bend the light
guide over a printed pattern, routed
template, or use free-forming. A
clean flat insulated surface (wood
or laminated countertop) will help to
prevent twisting or bowing. See the
chart above for minimum bend radius
guidelines.
