VFI®-270 70 A Polyurea Spray Coating

VFI®-270 70 A Polyurea Spray Coating

VFI-270 70 A Polyurea Spray Coating is a flexible spray-applied coating that creates a smooth, durable film on flexible surfaces. The two-component material is 100% solids and has fast-setting capabilities to achieve high builds on vertical surfaces without sagging. As a polyurea, it has resistance to impact and thermocycling as well as low moisture sensitivity for use in all environments. VFI-270 provides an elastomeric surface without adding too much structure or weight.

VFI-270 70 A Polyurea Spray Coating from VFI is a flexible, medium-hard coating that protects flexible surfaces for indoor and outdoor use.

Instructions for Use:

Surface Preparation

Coating failures often occur when the surface is not properly prepared. Clean all surfaces of contaminants such as oils, dirt, or debris for ensured adhesion. The surface must be sealed with a release agent, especially if it is porous and you plan on demolding. Some surfaces may require a primer, so an adhesion test should be performed before coating. VFI’s recommended primers include VFI-#11. When applying over foam, allow the foam to age for at least 30 days so any gas can escape.

Application

Before spraying, the B side (Poly) material must be mixed until uniform. Mixing time will vary based on the volume of material used and the mixing method. Bring the material to a minimum temperature of 65°F. The surface temperature should be between 40°F – 100°F during application.

VFI-270 should be sprayed using a high-pressure, high-temperature two-component spray rig. The spray equipment should be capable of heating the product and providing at least 2,300-2,500 psi of constant pressure. We typically recommend spraying between 40 and 80 mils for the best coverage. More coats can be applied for improved impact resistance. Projects can be put into service in as little as 4 hours, depending on application thickness, but full cure occurs in 3 days.

Cleanup

VFI recommends using xylene or MEK as a cleanup solvent. When flushing through spray lines, VFI-8005 Pump Flush can be used to remove the material from the hoses.

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.
