VFI®-202 50 D Fast Polyurea Coating

VFI®-202 50 D Fast Polyurea Coating

VFI-202 50 D Fast Polyurea Coating is a fast-setting, two-component, spray-applied coating that excels at low-build, thinner passes on prepared metal, concrete, and masonry surfaces. It is best used for industrial applications when spraying vertically or overhead and won’t drip. It creates structure over the surface to provide protection from chemicals, abrasion, and impact. The coating is perfect when a faster setting time is needed, and self-texturing is desired. VFI offers different polyurea formulas in slow (VFI-200) and medium (VFI-201) setting speeds based on application needs.

Frequently Asked Questions

Instructions for Use: 

Surface Preparation 

For quality adhesion, ensure all surfaces are clean, dry, and free of dirt, dust, or debris before coating. Clean surfaces containing oil and grease with a pressure washer. If mold, mildew, and fungus spots are present, treat them with a concentrated chlorine solution. Remove all loose paint, rust, and scale from the surface by sandblasting or grinding. The coating will only perform to its desired effect if all needed repairs are made to the surface prior to coating. When coating concrete, it must be aged a minimum of 28 days to prevent blisters from forming. 

Application 

Premix the Poly (B side) until uniform before applying the coating. VFI-202 should be brought to a minimum temperature of 65°F before use. VFI recommends applying the coating with a plural component high-pressure spray rig capable of spraying at 2,500 psi and temperatures between 135°F-150°F.  

Apply the coating at a minimum of 30 mil passes. If more coats are needed, you must apply them within the 15-minute open window. VFI recommends applying a UV-stable topcoat after VFI-202 has cured for optimal protection and UV stability. Allow the coating to cure for at least 24 hours.  

Cleanup 

Use xylene or MEK to clean application equipment. When cleaning spray lines, VFI recommends using VFI-8005 Pump Flush to flush uncured material out of the hoses.  

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 approved, fitted dust or splashproof chemical safety goggles and face protection such as a face shield 
  • 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-202 contains isocyanate, which causes skin irritation and can be toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors and repeated skin contact. Use only in a well-ventilated area. For applications exceeding 100 mils, it would require multiple passes to prevent excessive amounts of heat.  

  • Incompatible materials – A side: strong bases, acids, alcohols, amines, and water. B side: strong oxidizers and acids 
  • 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 and oxides of nitrogen, plus isocyanates for the A side 

Potential Health Hazards  

  • May cause stomach distress, nausea, or vomiting if swallowed. B side is toxic and may cause burns.  
  • May cause respiratory tract irritation, allergy and asthma symptoms, or breathing difficulties. B side may cause burns.  
  • Causes skin irritation and sensitization: redness, edema, drying, defatting, and cracking of the skin. B side is toxic and causes severe burns, redness, pain, and blisters when in contact with the skin. Repeated exposure to this material can result in absorption through the skin, causing a significant health hazard. 
  • Causes serious eye irritation or damage: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva. B side may cause burns.  

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

Frequently Asked Questions

How much does it cost?

VFI strives to keep our prices competitive, but it ultimately depends on the availability of raw materials and the materials used in the formula. Also, polyurea hybrids when compared to pure polyurea coatings provide a good balance of properties, moisture insensitivity, and price.

What happens if the bedliner is damaged? Is it repairable?

Yes, Volatile Free, Inc. offers a bedliner repair material called VFI-520 QS Bedliner Repair that you can use on scratches, blisters, and other damages. It can be applied by brush or injected using the VFI-7500 Qwik Spray Gun.

How to clean spray on bedliner?

Regularly remove dirt, debris, and other grime that has built up from use. You can use a hose or a pressure washer to clean the truck bed with soap and water. Avoid harsh chemicals that may damage the material.

How long do polyurea hybrid coatings last?

When applied correctly and regularly maintained, a spray on truck bedliner should last the entire life of the truck. If repair is needed, VFI offers a thickened polyurea hybrid as a repair material for scratches, gouges, and other blemishes.

Will the bedliner fade over time?

Yes. All VFI bedliners are aromatic, which means they are not UV-stable. If you want to maintain the color of your bedliner, you’ll need to apply a clear aliphatic top coat like VFI-2580.

How soon can the truck bed be used after spraying?

We recommend waiting at least 4 hours after application for light use of your truck bed and a full day (24 hours) before heavy-duty use. The bedliner will gain full strength and formulated properties 5 days after application.

How much material do I need to coat a truck bed?

When spraying VFI-544, we recommend using 6 cartridges (a full case). A full case is just under 2 gallons of material and gets you around 100 mils thick without any loss.

VFI-542 and VFI-543 can be ordered in drums or totes, so about 2 gallons from those containers will also coat one truck bed at around 100 mil thickness without any loss.

How thick should I apply the bedliner?

VFI recommends applying the material at a minimum of 80 mils for long-lasting results.

How long does it take to spray a truck bed?

It can take 2-4 hours to prepare the surface by sanding or priming, tape off areas you don’t want material to get onto, and then spray the truck bed.

Do I need a primer?

Primers are usually not required on properly prepared metal surfaces. Scuff the areas you are coating with a wire cup brush sander or 40-grit sandpaper. If you need a primer, VFI recommends either VFI-1016 Steel Primer or VFI-1017 Porous Surface Primer.

What surface prep is required before applying spray on bedliner?

The surface must be cleaned with acetone before application. Tape up the truck bed with wire trim tape and shield surfaces from overspray with plastic or paper sheets. Scuff sand the area you are coating with a wire cup brush sander or 40-grit sandpaper. Primers are usually not required if the metal is properly prepared.

What temperature should I use the material at?

VFI spray on bedliners must be sprayed between 40°F and 100°F. The cure speed of the material will increase if the temperature passes 72°F.

Does your spray on bedliner come in different colors?

VFI high-pressure, low-pressure, and Qwik Spray bedliners can be pigmented. The premium colors offered are light gray, red, blue, pewter, yellow, and green. These materials are not UV color stable and require an aliphatic top coat like VFI-2580 to prevent fading.

What kind of packaging do your bedliners come in?

For our high pressure bedliner, it can be purchased in drums or totes. The low pressure bedliner can be purchased in pails, drums or totes. The Qwik Spray formula comes in cartridges with 6 cartridges per case.

Is high pressure material better than low pressure material?

While some manufacturers will tell you that high pressure is better than low pressure bedliners, they both perform as expected. Our low-pressure spray bedliner is an economical option with a lower hardness (40 A) and a slightly slower cure than our high-pressure version. It may provide a slightly thicker texture, better for skid resistance. Either version will still provide the same quality and durability.

What are the application options for your bedliner?

VFI spray on bedliner comes in three formulas: high pressure, low pressure, and Qwik Spray for different processing needs.

Does the spray on truck bedliner withstand temperature extremes?

VFI bedliners offer extended protection from wear in extreme temperatures while maintaining flexibility to prevent cracking. They also form a seamless membrane to keep water from penetrating the surface, preventing rust and corrosion.

How are spray in bedliners better than drop in liners?

Spray in bedliners offer more durability than drop in liners. Drop in liners have to frequently be replaced because they crack, break, and warp over time. Spray in bedliners are an almost permanent solution to protect your truck bed. They form a seamless film over the prepared metal to keep out dirt, debris, moisture, and other contaminants. They are more likely to last the entire lifetime of your truck.

What is the difference between an aliphatic and aromatic bedliner?

Aliphatic bedliners are UV stable and will not fade over time, while aromatic bedliners will fade and chalk over time when in direct sunlight. Most bedliner on the market are aromatic, but VFI offers a clear aliphatic top coat to prevent color fading and degradation.

What is your spray on bedliner made of?

VFI’s bedliners are a cost-effective blend of both polyurethane and polyurea. They offer the best characteristics of each material, including properties, cost, and moisture sensitivity.
