Application of protective refinish coatings
Stone Chip Coatings and Underbody coatings are easily applied in the required texture with the 3M™ Accuspray™ Pressurised HGP Spray Gun and PPS™ Pressure Cups.
In every body shop, there is more or less regularly the need to apply higher viscosity materials such as high build primers or functional coatings. This process is usually not very user-friendly and involves a high amount of cleaning work - and cleaning is a task that can't be invoiced for.
3M™ Accuspray™ Pressurised HGP Spray Gun and PPS™ Pressure Cups are designed for high viscosity coatings such as underbody protection, high build primers and stonechip.
With the ability to control thickness and finish, the system allows for minimal waste in product and time, making it both efficient and effective - and additionally, any cleaning work is reduced to a minimum.
The Accuspray™ atomising heads / nozzles allow for different textured coatings to be applied, meaning you can easily match several different OEM textures to get the finish you need.
The PPS™ Pressure Cup takes air vented from the spray gun and pressurises it to ensure high viscosity material can be sprayed evenly. Pressurising the pot helps the bag to collapse and release the material.
Applying coatings with the 3M™ Accuspray™ Pressurised HGP Spray Gun you can:
-
Reduce spray time to boost productivity- No repeat layering of coating - just select the right setting.
- Achieve the required finish quickly, reducing the application time and allowing more jobs to be completed.
- Quick and easy cleaning, thanks to the easily removable and disposable nozzle.
-
Improve finish- Fluid control allows you to select the texture and thickness you want.
- The gun design and pressurised pot aids complete and even coverage.
- Controllable spray pattern.
- Paintable stonechip. (We recommend the stonechip coatings to be primed prior to basecoat application.)
-
Minimise waste to lower costs- The Accuspray™ HGP provides greater control for the application of coatings versus the conventional Schutz style gun, therefore reducing material waste.
- Minimal overspray.
- Less solvent is needed to clean up, thanks to disposable, removable parts (nozzle and liner).
- Always select appropriate Personal Protective Equipment - Eyewear, gloves, hearing and respiratory protection for your job and workplace!
Step-by-step guide
-
Step 1
Attach the air regulator to the Accuspray™ HGP gun. Two spanners should be used to ensure the connector is securely fastened.
-
Step 2
- 1.4mm Atomising Head / Nozzle for Flat / Fine Coatings.
- 1.8mm Atomising Head / Nozzle for Flat and Medium Textured Coatings.
- 2.0mm Atomising Head / Nozzle for Medium and Heavy Textured Coatings.
Choose your 3M™ Accuspray Atomising Head / Nozzle based on the finish you want to achieve.
Pull the trigger back on the gun and hold. Put the nozzle in place and ensure the release buttons are aligned with the latch openings.
The double click signals that the nozzle is fully engaged.
-
Step 3
Place the PPS™ liner in the PPS™ pressure cup and pour the required amount of coating into the liner. Once the liner is filled, pull the filter tab and remove it from the PPS™ lid. Attach the lid to the liner and push it into place to ensure it’s secure. Screw the black PPS™ collar onto the PPS™ pressure cup.
-
Step 4
Connect the flexible tube to the Accuspray™ HGP gun body side and then connect the air line to the regulator. Set the air pressure to 20 psi (1.4 bar) when the trigger is pulled and adjust the fan control from closed to open by making a 1/4 to 1/2 turn. The gun is now ready to use.
The 3M™ Accuspray™ Pressurised HGP Spray Gun offers outstanding control over texture build. Adjust the gun settings to get the texture you want.
-
Med to light textures
- Nozzle : 2.0 mm
- Air pressure : 1.4 bar
- Fan Control : ¼ to ½ turn
- Fluid Control : 1 turn
Heavy textures
- Nozzle : 2.0 mm
- Air pressure : 1.4 bar
- Fan Control : ¼ to ½ turn
- Fluid Control : 1 ½ turns
- To increase the heaviness of the texture, angle the gun 45 degrees to the workpiece and spray left to right. You may also want to reduce the air pressure.
-
Step 1
Disconnect the air line, pull back the trigger and release the fluid back into the cup.
-
Step 2
Remove the air line and the PPS™ Cup. If required, use the sealing cap to store for further use.
-
Step 3
With an appropriate solvent (or water for Waterbased Coatings), flush out the Accuspray™ atomising head / nozzle so it is clear of coating.
-
Step 4
Once you’re satisfied that the nozzle is completely clean, pull the trigger back and take the nozzle straight out from the gun body. Remove the nozzle in this way to avoid bending the fluid needle.
-
Step 5
Wipe the needle clean and inspect the nozzle for damage. If the nozzle is broken or worn, please dispose and use a new nozzle. If the nozzle is fine, it can be reattached and used on your next application.
- Keeping the 3M™ Accuspray™ Pressurised HGP Spray Gun clean is important to ensure its longevity and continued high performance.
