VFI®-6050 50 D Impact Resistant Hard Coat

VFI-6050 50 D Impact Resistant Hard Coat is a fast-setting, two-component, 100% solids, spray-applied coating capable of high builds and good resistance to impacts and abrasion. It is a general-purpose polyurea that has great adhesion to many surfaces, with properties that allow for flexibility when spraying vertically or horizontally. VFI-6050 is best used to create a structure over surfaces that need protection, including props, sets, custom signs, museum displays, and more.

Equipment

Apply the material to the prepared surface using a plural component high-pressure spray rig. The spray equipment should be capable of spraying at 2,500 psi and temperatures between 135°F-150°F. See technical data sheet for recommendations on machines.

Surface Preparation

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 the 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

Before spraying, premix the Poly (B side) until uniform.

Application Requirements

The material temperature should be brought to a minimum of 65°F before use. Apply the coating at a minimum of 30 mil passes. When applying additional coats, you must stay within the 30-minute open window. VFI recommends applying a UV-stable topcoat once VFI-6050 has fully cured for complete UV stability. Coated surfaces can be placed into service after a minimum cure of 24 hours.

Cleanup

VFI recommends cleaning application equipment with xylene or MEK. When flushing out spray lines, use VFI-8005 Pump Flush to remove all material from the hoses.

Storage/Shelf Life

Store between 60°F – 90°F in a clean, dry building. The shelf life of unopened containers is 12 months after the date of manufacture. Once opened, it should be used immediately. If you are storing after opening, the container must be nitrogen purged.

Precautions

VFI-6050 contains isocyanate, which is irritating to the skin and toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors and repeated skin contact. Do not add foreign material to the product. Use only with adequate ventilation. See Safety Data Sheet for complete safety information.
