Remove the protective lm 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.
3Fill the entire light guide channel with the GEXNBA
Silicone Bend-Aid(s) and press into place. Bend-Aid must
be installed prior to heating and forming.
NOTE: The GEXNBA Silicone Bend-Aid is reusable.
CAUTION: DO NOT heat and form the light guide with
the light engine installed.

Heating and Forming
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-
deecting 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.
CAUTION: Avoid direct contact between hot materials and exposed skin
or combustibles. Use heat resistant gloves while heating and/or handling
any hot materials.
CAUTION: DO NOT use an open ame to heat the light guide.
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. In order to remove
any minor surface aws, 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.
NOTE: DO NOT remove the Bend-Aids until the light guide has completely cooled.
NOTE: DO NOT subject heated light guide to freezing or quenching in water.
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 at insulated surface (wood or
laminated countertop) will help to prevent
twisting or bowing. See the chart above
for minimum bend radius guidelines.
