Excimer UV Curable Coatings

One of the primary advantages of RDC’s Excimer UV curable coating formulations is the technology’s ability to produce ultra-thin, zero-gloss coatings with minimal surface roughness. These finishes are impervious to fingerprints and other surface imperfections, making them ideal for electronic devices. Excimer UV curing allows for the formation of coatings that are typically less than 10 micrometers thick, providing a smooth finish that enhances the functionality and appearance of the coated product. This ultra-thin layer is ideal for applications that require high precision and performance, such as protective coatings on smartphones and other consumer electronics.

Another significant advantage of RDC’s Excimer UV curable coatings is the ability to tailor the surface energy and functionalize the coating to meet specific application needs. By adjusting the formulation and curing parameters, manufacturers can create coatings with precise surface characteristics, such as resistance to moisture and oils, or enhanced adhesion properties. The ability to customize the surface allows for the creation of coatings that meet specific functional requirements, improving overall product performance.

The Excimer UV curing process occurs at low temperatures, which is a crucial advantage when coating heat-sensitive materials. Unlike traditional UV curing methods that can generate heat, Excimer UV curing ensures that the temperature remains low during the curing process. The low temperature curing enables RDC’s custom Excimer UV coatings to be applied to materials like plastics, composites, and other heat-sensitive substrates without the risk of heat damage or thermal degradation. This low-temperature curing capability is particularly valuable in industries such as electronics, where maintaining the integrity of delicate components is essential.

RDC’s Excimer UV curable coatings offer several environmental and safety benefits, helping manufacturers achieve their sustainability goals. These coatings avoid volatile organic compounds (VOCs), reducing the emission of harmful chemicals into Earth’s atmosphere. Additionally, the energy consumption of Excimer UV curing systems is generally lower than that of traditional thermal curing systems, reducing an operation’s carbon footprint. The absence of significant heat generation during the curing process also improves worker safety by minimizing the risk of burns or heat-related injuries.

While an investment in Excimer UV curing technology may be more expensive than traditional curing methods, those costs can be offset by long-term savings and production efficiency gains. The rapid curing process increases throughput, reduces labor costs, and minimizes the time products spend in production. Additionally, as the sole technology capable of producing zero-gloss, anti-glare finishes — properties many consumers now demand — the market potential for products finished with RDC’s Excimer UV curable coatings remains virtually untapped.
