VFI®-2622 68 D Polyurethane Spray Coating

Features & Benefits

• Fast setting – cures to touch in 4 minutes and can be placed into service in 4 hours
• Fine texture – lays flat with slight texture from increased speed
• Excellent adhesion – can be used over plywood and metal
• Improved durability – encapsulates the surface and provides protection from the elements
• 68 D hardness – the tough, shell-like film allows substrate to withstand physical abuse from impact
• 100% solids – contains no VOCs

Instructions for Use:

Surface Preparation

Specific preparation will depend on application and surface being coated. For the best adhesion results, the surface should be clean, dry, and free of oils, dirt, films, etc. Depending on the substrate, sanding or priming may be required.

• Wood – The wood should be dry and contain less than 11% moisture; otherwise, it should be primed or mist-coated (apply a light dusting followed by the main application of the coating).
• Metal – The surface must be cleaned by roughly sanding or sandblasting to SP6 to remove rust, mill scale, dirt, and other contaminants.

Application

Before spraying VFI-2622 68 D Polyurethane Spray Coating, you must premix the Poly side (B) components until uniform. The time it takes to mix will depend on volume and mixing method. When the product is in use, the temperature must stay between 40°F – 100°F.

Use a plural-component, high-pressure spray rig to apply VFI-2622 over the substrate. The spray equipment should be capable of heating the product and providing at least 2,300-2,500 psi of constant pressure. Coverage will vary depending on desired structure, but VFI recommends applying the coating at a minimum of 30 mils. Some applications may even require 80-120 mils for increased durability. The material will need at least 4 hours to cure before placing it into service. Once cured, the coating can be sanded and/or painted to get the desired finish needed for aesthetic purposes. When spraying in thinner passes less than 40 mils, it may require a longer post-cure time.

Cleanup

To clean spray equipment, VFI recommends using xylene or MEK. Flush the cleaning solvent through the spray lines until fully removed.

 Safety

*Always read the safety data sheet before working with chemicals

Use chemicals only as directed and for their intended purpose. Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste.

PPE to avoid all unnecessary exposure:

• Eye protection – wear safety glasses and any additional eye protection as necessary
• Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene)
• Skin and body protection – wear suitable protective clothing
• Respiratory protection – in case of insufficient ventilation, wear suitable respiratory equipment. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product, and the safe working limits of the selected respirator

Product Limitations

VFI-2622 is not UV color stable and has no long-term UV testing. This product contains isocyanate, which may cause skin irritation and can be toxic if inhaled.

• Incompatible materials – A side: oxidizers. B side: strong oxidizing agents, acids, and bases
• Conditions to avoid – heat and incompatible materials
• Chemical stability – stable under normal storage conditions
• Reactivity & hazardous reactions – no dangerous reaction known under normal use
• Hazardous decomposition products – may include, and are not limited to, oxides of carbon

Potential Health Hazards

• May cause stomach distress, nausea, or vomiting if swallowed.
• Causes skin irritation and sensitization: redness, edema, drying, defatting, and cracking.
• May cause respiratory tract irritation. A side may also cause allergy or asthma symptoms and breathing difficulties.
• Causes serious eye irritation: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva. B side may also cause burns.

*If you are experiencing any of these symptoms, seek medical advice or attention. Call a poison control center or doctor if swallowed.
