Truck bed liners are protective coatings that shield the inner-side of a truck bed from damage and also create a skid resistant surface allowing any cargo to stay in place, depending on circumstances. There are two broad classifications of Bed liners: "Drop-in" and "Spray on/in". "Drop-in " bed liners are easily applied to the truck bed with no preparation work required, and can be easily removed as well for cleaning. Spray-in liners require specific preparation to allow the coating to adhere correctly to the bed; the better the coating can adhere will determine the length of life for the coating. "Sprayed On","Sprayed In","Spray On", "Spray In" (these terms are used interchangeably in the industry) come in two classes of material, and in two main types of application processes: aromatic and aliphatic compounds can be applied through a low pressure process (not heated) or high pressure process (heated). Performance greatly relies on the initial surface preparation done on the bed. It is now possible to have color matching bed liners to your vehicle, but with time color fade from UV radiation is inevitable. Aromatic is generally used for black and darker colors, and is the least expensive option. Aliphatic can be a better option for colors because it is UV stable. It is produced with pure polyurethane, which is driving up the cost approximately 35%. Aliphatic materials can be sprayed in a wide variety of colors, including metallic finishes. Spray-on bed liners can be applied by roller, low pressure, cartridge driven by an air compressor or high pressure machine. Environmental conditions such as humidity, temperature, wind, and elevation can affect the cure process of a spray in bedliner. Such things as nozzle aperture, thinners and spray pressure are modified to allow proper distribution of the spray lining chemicals. == Differences in Spray in Bed liners == Spray on bed liner material can vary in texture as well as color. Texture can be smooth for easy cleaning or rough to prevent skidding. Polyurethane can be sprayed from 1/16 inch to 4 inches, depending on the application. Thinner coatings may cost less but can chip and crack. Thicker coatings destroy the shape and size of the truck bed. For trucks with the most rugged use, ArmorThane sets optimum thickness for bed liners as 1/4 inch on the bed and wheel wells and 1/8 inch on the sides. When applied correctly, the value of a truck bed liner is that it resists denting, scratching, and holds shape firmly, yet is flexible enough to not crack when navigating through rough terrain. Unlike a metal bed, it absorbs vibration to protect cargo. Whereas painted metal will chip and rust under rough conditions, polyurethane coatings prevent damage from scratching and from most chemicals, and therefore avoid rusting. Spray on truck bed liners require a professional applicator who has the training and experience to follow the process and deliver a smooth, even surface. The process requires sanding to create a surface for the polyurethane to attach. This allows the polyurethane to bond permanently so it will not bubble even in extreme weather. The choice of colors is virtually unlimited. A color matching system sprays to OEM specs or owners can choose custom colors. Adding a UV stabilizer maintains the appearance even in prolonged direct sunlight. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Truck bedliner」の詳細全文を読む スポンサード リンク
