VFI®-6071 70 D Qwik Spray Hard Coat

VFI-6071 70 D Qwik Spray Hard Coat is a 100% solids, polyurethane coating applied with the cartridge-based Qwik Spray System. It is capable of being sprayed over CNC or hot wire cut EPS to create a protective, uniform surface. The Qwik Spray System only requires the VFI-7500 Qwik Spray Gun with an air compressor capable of 10 CFM at 100 PSI of constant pressure, allowing for easy equipment startup and low maintenance. Its chemical makeup allows it to spray smoothly with limited need for sanding after spraying. Spraying VFI-6071 allows you to create a variety of shapes for various theming applications, including props, sets, signs, museum displays, and more.

Thickness Requirements

We recommend spraying at a minimum rate of 60 mils or greater to create the best film properties. If subsequent coats are needed, you must stay within the 20-minute open window. If you exceed the open window, we recommend using a primer to create adhesion between layers.

Equipment

VFI-6071 must be used in conjunction with the VFI-7500 Qwik Spray Gun and an air compressor that can provide dry air and a minimum of 10 CFM at 100 PSI of constant pressure. We recommend that you heat the material up to room temperature (77°F) while spraying. Do not heat the material in a microwave. Once you begin spraying, you cannot stop until the cartridge is empty without switching tips.

Surface Preparation

EPS – Ensure that the EPS has been aged at least 30 days. Anything between 1 and 3 PCF is acceptable, but for an optimal cost-to-quality ratio, we recommend using 2 PCF foam. Once clean and dry, the hard coat can be applied directly to the EPS.
Wood – The wood should be dry and contain less than 11% moisture; otherwise, it should be primed or mist-coated (a light dusting of the coating followed by the main application of the coating).
Urethane or Plastic – First, sand the urethane or plastic and then apply a general urethane primer to ensure good adhesion to the substrate.

Mixing

As a cartridge system, mixing is not required unless the material is visibly separated. If there is visible separation, shake the cartridge until a uniform mix is achieved.

Application & Cleanup

The material will need at least 3 hours to cure before heavy movement is allowed, but it is sandable within an hour. Light movement is acceptable sooner than 3 hours if needed. If spraying in thinner passes, it may require a longer post-cure time.

One of the great features of the Qwik Spray System is that cleanup is easy. You’ll disconnect the cartridge from the air-atomizing tip, remove it from the applicator frame, and throw it away. If there is residue on the gun, xylene or MEK can be used before it has time to set. Never soak the gun in any cleaning solvent.

Storage/Shelf Life

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