Truck bed liner is a protective coating that is applied to the floor of a truck bed, or the interior walls of the truck body. It is designed to protect the metal parts of the truck from corrosion and damage caused by abrasive materials like sand, gravel, and rocks.
The most common type of bed liner is spray-on bed liner, which is sprayed on in liquid form and then allowed to harden. This type of bed liner provides excellent protection against abrasive elements and moisture.
Truck bed liners are made out of a variety of materials, including rubberized polyurethane elastomers, polymers, vinyls, plastics, and epoxies. These materials have different levels of durability, flexibility, and abrasion resistance depending on their composition.
Some contain UV inhibitors for improved resistance to fading or cracking from sun exposure. Others may be infused with additives to provide additional protection against rust or other forms of corrosion.
The spray-on type of truck bed liner is generally applied in two coats: a base coat that contains the primary material plus any additives like UV inhibitors; and a top coat that provides improved adhesion and weatherproofing. The base coat is usually composed of rubberized polyurethane elastomers mixed with solvents or surfactants for better adhesion. The top coat usually contains resins or other polymers that enhance its durability.
Conclusion
Truck bed liners are designed to protect the metal parts within your truck from damage caused by abrasive materials. They are typically composed of rubberized polyurethane elastomers mixed with solvents or surfactants for better adhesion along with resins or other polymers in the topcoat for improved durability. Some may also contain UV inhibitors for additional protection against fading or cracking due to sun exposure.
