BODY SEALING MATERIALS
MATERIALS AND APPLICATIONS 77-3-5
Cooper Pegler Falcon Junior Pneumatic Gun (Airless)
Intended primarily for applying transit wax, this pneumatic sprayer has a 5-litre container with integral hand pump and
provides an effective means of wax spraying without the need for compressed air or additional services.
A selection of nozzles, lances, hose lengths and a trigger valve assembly with integral filter allows flexibility in use.
Additional applications include general maintenance, wax injection and paint application. Heavy-bodied materials
may also be applied. All parts are fully replaceable and a wide range of nozzle configurations is available.
SATA Schutz Gun Model UBE
The SATA Schutz Gun is approved for the retreatment of vehicle underbody areas with protective coatings as
supplied in 1 litre, purpose-designed 'one-way' containers. The screw thread fitting (female on the gun) is standard
to most Schutz-type packs.
SATA HKD1 Wax Injection Injection Equipment
This equipment is approved for carrying out cavity wax re-treatment. The SATA HKD1 set comprises a high quality
forged gun with 1-litre pressure feed container, a flexible nylon lance, a straight 1100 mm (43.307 in) steel lance and
hooked- wand lance. A quick-change coupling is provided as a standard fitting to allow lances to be easily
interchanged. Each lance has an integral, machined nozzle with specialised spray characteristics to suit the type of
box section to be treated.
NOTE: Always clean gun after use with appropriate solvent to maintain efficiency.
Specifications of Model UBE:
Air consumption 7 ft

spray pattern
When re-treating wax-injected areas which have been disturbed during repairs, it is necessary to use a compressed
air spray gun with integral pressure cup and a selection of interchangeable lances.
The following points must be observed during use, according to the attachments fitted:
lUse the rigid or flexible lance attachments with 360° spray dispersal when treating enclosed areas, to ensure
maximum coverage;
lWhere openings are restricted, use the hook nozzle to provide a more directional spray (e.g. inside narrow or
short box sections);
lSpray exposed underbody surfaces directly from the gun less lance attachment and without disconnecting the
fluid coupling.
1100 mm (43.307 in) rigid lance
The nozzle on the rigid lance produces a 360° circular spray pattern combined with a forward-directed spray. Although
wax is distributed to all box section surfaces in a single stroke, effective and complete coverage is obtained in long
straight structures and box section cavities by spraying on both inward and outward strokes of the lance.
The rigid lance also provides the positional accuracy required in shaped sections, by allowing visual assessment.
CAUTION: Do not force the lance into access holes when using this attachment.
1100 mm (43.307 in) flexible nylon lance
This lance is similar in pattern to the rigid version, but provides the additional penetration required for curved sections
or in places where access is difficult. Its main limitation is a lack of positional accuracy inside box sections.
Carry out all spraying on the outward stroke of the lance. Withdraw the lance slowly to ensure sufficient coverage. Do
not withdraw the lance too quickly.
Ensure that the nylon tube of the lance is kept away from the edges of the access hole to eliminate abrasion and
extend the life of the tube. Take care to ensure that spraying ceases just before the nozzle emerges from the access
hole. To assist in this process paint the final 30 mm (1.181 in) of the nozzle with RED paint.

MATERIALS AND APPLICATIONS 77-3-7
Hook nozzle on flexible lance
The rigid hook produces a highly atomised, forward-directed, fully conical spray pattern having long range and good
dispersion characteristics. This combination has good directional capabilities for treating short, narrow sections, and
may also be used for direct spraying of inner wheel arches etc.
In use, position the flat area at the end of the lance at 180° to the nozzle spray direction. This will help to guide the
spray more accurately when it is concealed in a box section or access hole.
For general spraying, move the nozzle in an arc from side to side as required, to ensure full coverage.
NOTE: Always clean gun after use with appropriate solvent to maintain efficiency.
