VFI®-6041 40 D QS Impact Resistant Hard Coat

Equipment

The Qwik Spray System does not need special training to operate. The material requires a plural component Qwik Spray Gun, like VFI-7500, with dual 750 mL cylinders. To operate the gun, you will need an air compressor that can provide dry air and a minimum of 10 CFM at 100 PSI of constant pressure.

Surface Preparation

All surfaces must be clean, dry, and free of any oils, dirt, or films that may affect adhesion.

• Metal – Clean all surfaces with acetone or MEK and allow the cleaning agents to dry. Scuff all areas you are spraying with a wire cup brush sander or 40-grit sandpaper. Avoid sanding to bare metal, as this can affect adhesion, causing the coating to peel over time. Use acetone or MEK again to clean surfaces and allow them to dry before spraying. While primers aren’t necessary on properly prepared surfaces, they can increase adhesion on other surfaces.
• Wood – The wood should be dry and contain less than 11% moisture; otherwise, it should be primed or mist-coated with a light dusting of the coating, followed by main application.
• EPS/HDPU – The foam must be aged for at least 30 days so any gas can escape. We recommend using non-recycled EPS bead 2 PCF foam for an optimal cost-to-quality ratio, but 1-3 PCF is acceptable.

Mixing

The material should be brought to a minimum of 75°F before use. Mixing is not required unless the material is visibly separated, and if so, the cartridge should be shaken until uniform.

Application Guidelines

The temperature should be between 40°F – 100°F during use. The cure speed will increase if the temperature passes 72°F. Connect the Qwik Spray applicator to a dry air source. Keep the cartridge vertical with the label facing up when loading it into the gun. Once you start spraying, you cannot stop, so plan your spray pattern for even distribution. Spray onto a disposable surface to ensure the material is adequately mixed. VFI recommends spraying a minimum of 80 mils for the best results. Once the cartridge is almost used, spray onto a disposable surface to keep off-ratio material from getting onto the surface.

To apply texture, spray over but not directly onto the surface until the desired finish is achieved. Allow the material to set for at least 20 minutes before painting. A flexible paint must be used to avoid cracking. Once cured, it is ready to be placed into service after 24 hours. Allow 5 days for full cure.

Cleanup

Disconnect the disposable cartridges from the air-atomizing gun tip, remove them from the applicator frame, and throw them away. If there is residue on the gun or other equipment, use xylene or MEK before it sets. Never soak the gun in any cleaning solvent.

Storage/Shelf Life

Store between 60-90°F in a clean, dry building. The shelf life is 6 months after the date of manufacture.

Precautions

This material contains isocyanate, which can irritate the skin and is toxic if inhaled as particulate matter. Do not thin or add foreign material to this product. Avoid prolonged breathing of vapors and repeated skin contact. Use in a chemically approved spray booth with all necessary PPE, including a supplied air respirator or respirator with forced air ventilation. See the Safety Data Sheet for all safety information.
