The relationship between emissions and VOC content, though obviously direct, is not linear; in other words, the transfer efficiency of the application method also can have a significant impact on the amount of VOCs emitted. This issue is explored in chapter 7 (Falcone, p. 35). High-Solids Coatings General Description. j '. Low-Volume, Low-Pressure Spray Guns Low-volume, low-pressure (LVLP) spray guns are quite similar to HVLP spray guns in that atomized coatings are released at lower pressure ( to 10 psi) and lower velocity than conventional air spray guns. The transfer efficiency of LVLP spray guns is reportedly about the same as for HVLP spray guns. Sames-Kremlin will discuss new developments in spray guns, paint and powder coating application, improving transfer efficiency and reducing VOCs in your finishing operation.

Transfer efficiency is critical to the spray finishing industry from both a cost and a regulatory standpoint. With high transfer efficiency, manufacturers can save money and reduce VOC (Volatile Organic Compound) emissions.
Although transfer efficiency is a relatively simple concept, TE ratings can lead to considerable confusion (or even. Conventional spray guns equipment has a transfer efficiency in the range of 20% to 40%, and therefore most of the paint becomes an over spray that may contaminate the air in the worker’s breathing zone (Heitbrink, ).
High Volume Low Pressure Spray Guns High Volume Low Pressure (HVLP) spray guns are systems which use a high volume (30 cfm. The company says the gun offers more than 85% transfer efficiency with minimum overspray.

Pollutant releases to other media are considered in less detail. The following report describes the verification of the performan ce of EXEL Industrial, Inc.’s Kremlin Aimix® high transfer efficiency (TE) spray gun for wood finishing applications.
As seen, any correlation between efficiency testing claims and actual results in the field are usually haphazard at best. Three methods of testing spray equipment coating efficiency will be discussed. Transfer efficiency testing. Cost per square foot applied 3.
Cost per part applied. Transfer Efficiency. Determine VOC Content — For each coating that you use, indicate its VOC content in pounds per gallon (lbs/gallon). To determine the VOC content of the coating, consult the (MSDS), VOC data sheet, or contact the coating manufacturer. If the MSDS gives a range (e.g., %), use the highest number in the range (e.g., 5%).
Calculating Emissions from Coating and Painting Operations This guide explains how to calculate emissions of volatile organic compounds (VOC), hazardous air pollutants (HAP) and select toxic air contaminants (TAC) Transfer efficiency and VOC emissions of spray gun and coating technologies in wood finishing book common the amount of coating applied, the transfer efficiency*(TE) of the coatingFile Size: 1MB.
National emission standards for hazardous air pollutants (NESHAP) for aerospace manufacturing and rework operations were published on September 1, (60 FR ). While these final standards address the reduction of HAP emissions, the control techniques required by the NESHAP will result in reductions of VOC emissions as well.
Transfer Efficiency = Wt. of solid coating deposited on part (lbs) Wt. of solid coating used during the application (lbs) Weight of solid coating used during the application (g) is the amount of solid coating that is issued from the spray gun or other application device during the process. transfer efficiency, you need to control the factors that influence the efficienc y of the transfer of mater-ial to the target.
The primary spray finishing conditions that impact transfer efficiency are: • Substrate (target or part) characteristics, such as size and shape • Operator variability • Atomization and spray finishing methods.

powder inks, carbon paper, typewriter, and duplicating inks. Paint, ink, and other coating manufacturing can be classified as a batch process and generally involves the blending/mixing of resins, pigments, solvents, and additives. Traditional paint, ink, and other coating manufacturing consists of four major steps: # Preassembly and premix.
Conventional however has the best ability to break up thick coatings and Air Assist Airless has the highest production ability with transfer efficiency similar to an HVLP Spray Gun. When it comes down to pure finish quality Conventional and LVMP guns will provide the nicest finish, but LVMP spray guns are more efficient making them a perfect choice for wood finishing with stains, sealers.
VOC and Exempt Solvent Emissions from Wood Coating Line Cleanup Operations. A similar methodology to the methodology described in Section was used to calculate the short-term and annual VOC and exempt solvent emission rates from the proposed OKI wood finishing operations, as shown in Table HVLP HVLP = High Volume Low Pressure - low spray pressure ology for an internationally recognized low-pressure technology whereby the transfer efficiency rate has to exceed 65%, while the maximum air cap pressure is below bar.
X» / RP RP is an acronym for Reduced Pressure - optimized high pressure spray guns which achieve perfect finishes as well as transfer efficiency. Abstract The surface coating industry is rapidly changing to meet environmental and economic pressures. Some of the changes include new formulations which meet environmental regulations, higher performance finishes with improved properties, continued development of solventless technologies such as powder coatings and radiation curable coatings, and new application methods with improved.
assisted airless spray equipment, to reduce VOC emissions and to increase transfer efficiency. Planned Future Waste Reduction Projects Realizing the cost savings and environmental benefits of eliminating waste, Gerry is vigorously pursuing reuse of the collected overspray from its spray coating.
In this study, the total flow of emissions was not considered, given that the emissions were measured from wood-coating processes, where the emission concentration limits set by EU legislation (Directive /13/EC, ) are based on solvent usage per year.
The most complete type of source emission testing is continuous by: Conventional spray guns have a disadvantage because they are susceptible to overspray, resulting in more waste and less transfer efficiency.
Overspray uses more paint, increasing VOC emissions from the solvents in the finish. 3. Gun Target Distance: The spray gun should be between 6” and 12” to provide the best transfer efficiency. Theoretically, you can improve transfer efficiency by using the gun closer than 6”, but often the aerodynamics of the powder around the gun spray pattern device will disrupt the electrostatic attraction forces and cause the opposite.
METHOD 2: FIND THE OVERALL VOC EMISSIONS FROM THE COATING To find the VOC emissions from an overall coating, first find the Overall VOC Content* of the coating. The Overall VOC Content is the Overall Weight of VOC in the Coating divided by the Total Parts in the Coating.
Overall Weight of VOC – For each component, multiply its VOC of Material by the Mix Size: KB. Thus, the regulatory standard for finishing equipment is a 65% transfer rate at no greater than 10psi spray pressure. In practice, 65% transfer efficiency is rarely achieved.
Dux believes that even the highest quality HVLP spray guns will only achieve transfer efficiency between 35% and. SATAjet® B HVLP HVLP = High Volume Low Pressure - low spray pressure ology for an internationally recognized low-pressure technology whereby the transfer efficiency rate has to exceed 65%, while the maximum air cap pressure is below bar.
As versatile as you. The premium spray gun SATAjet B sets new quality standards, while painting. tests, HVLP guns were shown to improve TE by % to % when compared to conventional paint spray guns, depending on the coating sprayed.
This improved TE resulted in a reduction of 16% to 40% of coating material use, emissions of volatile organic compounds (VOC) and hazardous air pollutants (HAP), and of solid waste generated. Wood Finishing. A woodworking project is often judged on its finish quality alongside the craftsmanship.
Woodworkers worldwide have long sought a safe, foolproof, predictable method of applying stains, lacquers, shellacs, paints, urethanes, and waterborne finishes. Today, Apollo Sprayers meets and exceeds those needs with the world’s most advanced HVLP Turbospray systems—including the.
The coatings were gaining visibility at a time when green certification was also in the spotlight, and volatile organic compound (VOC) content was often the only criterion being used to measure a coating’s success.
The fact powder is VOC-free was its biggest selling point. However, liquid paint has had more staying power than many predicted. These advancements provide a compact applicator with the equivalent – or better – performance and transfer efficiency of higher voltage competitive guns The RansFlex Quick Fan Adjust applicator, is an air atomizing electrostatic applicator powered by an onboard generator that provides best in class atomization in a lightweight, user.
DeVilbiss and Binks invented the world’s first “stand alone” HVLP and Compliant technology spray guns, resulting in a revolution in the way spray guns atomise paints. Today our products are the bench mark for atomisation and paint transfer efficiency.
