While the apparent benefits seem advantageous, it’s also important to note that HVLP applications require more experienced painters due to the higher transfer efficiency.Īlthough they tend to be the most commonly used application methods, spray applications are not the only option for manufacturers and finishers. Since the paint is released at a lower velocity, this technique yields less overspray and blowback than conventional air-atomized equipment. HVLP spray equipment utilizes spray gun atomization technology that propels large quantities of low-pressure air to the gun applicator. This technique also presents a more significant fire hazard in the workplace. Electrostatic equipment is designed for specialized paints that have a specific conductivity, so the options are limited to specific chemical compositions. While this method can reduce wasted materials significantly, it also requires skill and precision to safely use. This allows for a smooth and solid coat with minimal effort, even for objects with corners and contouring. The equipment charges the paint particles with high voltage, causing them to be attracted to the surface of the part and will actually wrap around the part which increases transfer efficiency. Electrostatic TechniquesĮlectrostatic applications are a relatively modern innovation that offers exceptional transfer efficiency compared to other spray techniques. While it does offer several advantages over conventional techniques, airless spraying also requires additional equipment maintenance as well as advanced skill on the part of the operator. This method propels paint particles at a lower velocity than conventional air-atomized equipment, so there is less loss of paint through overspray. Rather than mixing liquid paint with compressed air, airless application equipment simply forces the liquid coating through a narrow opening to create pressure.
Spray booths also need to be sufficiently exhausted to ensure workers are not exposed to dangerous levels of airborne chemicals.Ĭheck your email for your copy of "How to Design the Perfect Spray Booth" Airless Spray The equipment has poor transfer efficiency compared to other application methods, although the relatively low labor requirements can help offset the material costs. One of the primary drawbacks of air-atomized technology is loss of paint. Since the equipment can be adjusted and customized to suit the needs of the operator, air-atomized applications are highly flexible and can be used on almost any kind of substrate.
The applicator consists of a traditional spray gun that combines compressed air with liquid flow to create a pressurized mist that coats the object. There are a variety of different types of spray methods currently in use, including:Īir-atomized applications are the conventional approach to spray painting. Spraying is the most prevalent paint and finish application technique among industrial manufacturers due to its versatility and economic viability. Take a look below, where we breakdown the benefits and drawbacks of the most common types of application methods. This makes it imperative for you to understand your logistical and budgetary requirements in order to select the right method for your operation. There are specific advantages and drawbacks to each of the application methods and many of them have several variations that are best-suited for specific circumstances. There are dozens of different techniques available to manufacturers and finishers when applying paint or finish to a manufactured product.
