Electrolube launches a global-first for conformal coatings
30 November 2021
Global electro-chemicals manufacturer, Electrolube, a recent acquisition of MacDermid Alpha Electronics Solutions, has launched a game-changing new conformal coating for the electronics community. UVCLX UV Cure Coating Xtra is a first-to-market bio coating with 75% of the organic content obtained from renewable sources.
The eco-friendly coating innovation is one of Electrolube’s most versatile, high-performance coatings yet for protecting electronic circuitry against the harshest of environments, particularly within the automotive industry, where components are at elevated risk from chemical attack.
Coating materials have traditionally been formulated in solvent-based form; however, the use of solvents has become more restricted from an environmental point of view, and consumers are increasingly becoming aware of the ‘waste’ of these processes, in the form of the energy required to remove the solvents, as well as the impact of their release on the environment. Electrolube’s new UVCLX solvent-free technology responds to the needs of both manufacturers and consumers, based on global ethics, performance and process.
The ground-breaking new UVCLX is a bio-based conformal coating that is completely unique to the industry, and provides the highest levels of protection, while maintaining a swift processing time. Applied via a selective coating machine, UVCLX exceeds traditional UV Cure Coatings, being touch dry after just a short exposure to LED-365nm UV light. UVCLX guarantees full cure in less than 24 hours, by virtue of the secondary chemical cure mechanism, which ensures that even shadowed areas are fully cured in a matter of hours. UVCLX performs in stark comparison to traditional UV Cure Coatings, that can require weeks at a time for a complete cure, and still with some shadowed areas remaining uncured. Inevitably, UVCLX enables a reduced level of work in progress.
Optimally applied at between 200-350µm, the new bio coating achieves excellent edge coverage, even over sharp components, and the highest levels of protection, even during temperature cycling and thermal shock, vastly out-performing other UV coatings on the market, even in the harshest environments. UVCLX offers exceptional performance due to its hydrophobic nature, which ensures it provides excellent protection against moisture, salt mist and even full immersion for short periods. This immersion period can be extended by applying the coating more thickly.

From a performance point of view, solvent-free materials are applied slightly more thickly, resulting in increased coverage and greater protective capability. The formulations are inevitably also more modern and deliver improved capability to meet the increased protective demands of new applications, for instance, automotive industry thermal shock cycling or aerospace increased condensation resistance.
UVCLX is characterised by greater coating thickness and enhanced edge coverage and shows improved adhesion, abrasion, scratch and solvent resistance when compared to conventional single component coatings. The rapid curing, tough yet flexible solvent-free coating also provides excellent resistance to chemicals and thermal shock.
Electrolube is proud to be part of MacDermid Alpha Electronics Solutions, providers of over-arching solutions for the circuitry, assembly and semiconductor sectors of the electronics industry, at every step of the supply chain.
