When working with bulk sealant or hot Spacer
melt extruder gun, it’s crucial to follow
these steps: Primary Sealant
(PIB)
Heating and Preparation: Desiccant
Ensure that the gun and sealant
are heated to the manufacturer’s Secondary
Sealant
recommended specifications. Allow Sealant to Flush
sufficient time for this process. to the Edge of
the Glass
Clamping Units:
To ensure a tight seal, clamp the glass
units on all sides. You can use Spring
Clamps with vinyl-coated jaws for this
purpose.
If you’re sealing multiple units, you can
stack them with separation. For units
of different sizes, use wood blocks or
paper between them. Place wood blocks
approximately 1" from the edge and 4"
from the ends. Start with the largest unit
at the bottom. When stacking larger units, ITEM NO. FHC96
(See Page IG31)
limit the stack to a maximum of 15 units.
Bulk Hot Extruder Gun Application:
Load the sealant into the tank and wait for
it to completely melt. Apply it to the edges
of the unit. Ensure that enough sealant is
applied to penetrate into the shoulders of
the spacer to create a proper seal. Avoid
using so much sealant that it displaces the
spacer. Focus on applying extra sealant to
the corners, which are the most vulnerable
areas of the unit. Remove excess sealant.
Ensure that the sealant completely fills the
back-set and is flush with the glass edges.

Check for Newton Ring:
Inspect the bottom units of the stack for a “Newton
Ring” effect in the center of the unit. This occurs when
two pieces of glass are in contact.
If you observe a Newton Ring, flip the affected units
upright and repair them before transport to prevent
permanent rub marks.

Following these steps will help ensure a proper seal
and the longevity of your insulating glass units using
FHC sealant.
