Powder coatings provide significant process and environmental benefits in MDF applications, including zero VOC emissions and the ability to coat complex 3D shapes and heat-sensitive substrates.
Electronic proportioners offer a number of benefits. The systems can provide accurate two- and three-component proportioning, including the ability to handle single and multiple color applications. Furthermore, they offer the ability to handle a wide range of operating ratios with a high degree of ratio accuracy at various flow rates.
A warm winter forecast and adequate natural gas supplies were supposed to keep natural gas prices in the U.S. in check, at least in the short term. Instead, natural gas prices have continued to be highly volatile, thanks to a bottleneck in storage and pipeline capacity.
Product cure quality and consistency are of primary importance to custom coaters and in-house coating lines alike. Various factors can affect the quality of cure, including peak temperature, time at temperature or the rate of temperature change. Conditions can change within a curing oven, and that same oven’s performance can alter over time.
Wood finishing technologies must take into account the nature and structure of a substrate that, by definition, is a “living material.” The first step in wood finishing is always drying the wood to reduce the water content from 60-70% to 15-20%, a moisture content that is in balance with the atmosphere’s moisture.
Most organic coatings used today involve a chemical reaction to cure or set the finish. Some require elevated temperatures or ultraviolet (UV) radiation to accelerate the curing and therefore manage the finishing process time. Plural component technology, in some cases referred to as 2K (from the German 2-komponent), employs an alternate technique.
As environmental regulations in the finishing industry become increasingly stringent, companies are constantly on the lookout for technologies that can help them remain in compliance. One possible solution is a paint overspray arrester that uses water to capture volatile organic compounds (VOCs), along with the overspray.
Dear Joe,
What are some possible causes for bubbling of powder over e-coat? I am a custom coater who occasionally powder coats an e-coated carbon steel (hot-rolled pickled and oiled) part for a particular customer.
