These operate connected to a high pressure pump commonly found using 300 to 7,500 pounds per square inch (2,100–52,000 kPa) pressure to atomize the coating, using different tip sizes to achieve desired atomization and spray pattern size. This type of system is used by contract painters to paint heavy duty industrial, chemical and marine coatings and linings.
Advantages of <strong><a href="http://www.spraygun.net.cn/p-Airless-Spray-Guns-89706/">airless spray guns</a></strong> are:
1.The coating penetrates better into pits and crevices.
2.A uniform thick coating is produced, reducing the number of coats required.
3.A very "wet" coating is applied, ensuring good adhesion and flow-out.
Most coatings can be sprayed with very little thinner added, thereby reducing drying time and decreasing the release of solvent into the environment.
Care must be used when operating, as airless <strong><a href="http://www.spraygun.net.cn/">Spray guns</a></strong> can cause serious injury, such as injection injuries, due to the paint ejecting from the nozzle at high pressure.
