In the 1980’s spray-on truck bed liners started replacing drop-in liners. This is because spray-on liners are generally stronger and more durable while adhering directly to the body of the vehicle avoiding the damage caused by abrasion from the liner rubbing against metal surfaces.
Spray-on materials are highly durable and seamless, making it difficult for metal surfaces to become exposed, preventing corrosion. There are a number of polymers that are used for this purpose. The most advanced of these being polyurea.

Why Polyurea Truck Bed Liners Have Become the Popular Choice?

Durability. Polyurea is a strong material with a high degree of elasticity, making it ideal for hard working areas like truck beds. It is also water and chemical resistant.
Temperature tolerance. Polyurea can be used over a wide temperature range without losing its form or protective properties – from -25 degrees through up to 300 degrees Fahrenheit with some special formulations.

No VOC’s. Volatile organic compounds (VOC’s) are an environmental hazard and many states restrict the use of products that use VOCs. Polyurea is a safe product, containing zero VOC’s.

Faster drying time. Polyurea dries faster than any other polymer, as little as 3-5 seconds. This makes it favorable for vehicle owners having their vehicles sprayed, as they can put the vehicle back into use very quickly after application. For spray shop owners, this is beneficial because you won’t have vehicles taking up vital shop space while waiting for finished surfaces to dry.

Adding color. Pigments can be added to match the vehicle’s color; even metallic colors can be used. In addition to this, UV inhibitors can be added to prevent colors from fading over time. 

How to Use Poyurea?

A great benefit of using polyurea is that it does not require a catalyst. This means there is no need to calculate mixing ratios, 1 to 1, reducing the risk of incorrect mixtures.  In general, polyurea spray equipment is your best option for application.  Scorpion offers a wide range of truck bed liner pumps: from Graco models, PMC models and Scorpion Series Pumps.  These high pressure pumps are the keystone to a smooth application process on any bed liner or other polyurea spray projects.

Polyrea is the most advanced product used for truck bed liners and many other spray coating applications.   It’s strength, versatility and low environmental impact are obvious benefits. If one adds to this the fact that it is easy to use, even under adverse climatic conditions, it’s easy to understand why it has become such a popular choice.
