In a groundbreaking exploration by Products Finishing titled “Low-Temperature-Cure Powder Coatings Offer Unique Opportunities,” the evolution of powder coating technology takes center stage. Traditionally, cure conditions required temperatures of 375-400°F, but over the last three decades, innovative formulators have pushed the boundaries to develop low-temperature-cure (LTC) powder coatings.
LTC coatings, now commonplace in the industry, present numerous advantages, including energy savings, enhanced color control, and the ability to cure across varying metal masses. This technology stems from strategic formulating, utilizing catalysts and high-flow resins to achieve curing temperatures as low as 325°F. This breakthrough allows for diverse applications, including heat-sensitive substrates like plastics, composites, engineered boards, gypsum, and hardwoods.
The benefits extend to reduced oven temperatures, offering significant cost savings for powder applicators. The transition from standard to low-curing alternatives requires careful evaluation, considering factors such as product and oven engineering, metal density, and surface area. A glance at Table 1 in the article illustrates the potential energy savings of reducing oven temperature from 375°F to 325°F on a conveyorized finishing line.
