Theory of Operation
External Mix
The independent material stream, resin or gelcoat, and
catalyst impinge when they exit the spray tip. The cata-
lyst is atomized with air pressure and is contained by
AAC air to achieve high mix quality. This reduces inter-
nal clogs from cured material.
Internal Mix
The material and catalyst pass through an internal static
mixer where they mix. The mixed solution is dispensed.
Chop Guns
Fiberglass is pulled through cutter and cut into small
strands. The cut strands are then dispensed into the
mixed material stream.
Impingement versus Standard
Spray Tips
Impingement spray tips are typically for chop guns. This
utilizes multiple impinging streams to create the fan pat-
tern.
Standard spray tips are typically for gel guns. This uti-
lizes a single cat-eye shaped orifice to create the fan
pattern.
Air Assist Containment (AAC)
When material exits the spray tip, air is sprayed against
the material stream to shape it into a more consistent
pattern.
Grounding
Trigger Lock
This equipment must be grounded.
Grounding reduces the risk of static shock by providing
an escape wire for electrical current due to static build
up or in the event of short circuit.
NOTE: Grounding wire and clamp assembly 17440-00
is included with Graco FRP proportioner. If using a dif-
ferent proportioner that does not come with a ground-
ing wire and clamp assembly, order 17440-00 or
provide your own.
Ground the dispense gun through connection to a
Graco approved grounded fluid supply hose.
Check your local electrical code and related manuals
for detailed grounding instructions of all equipment in
the work area.
Engage trigger lock whenever you stop spraying to
avoid accidental triggering.
