MacDermid Alpha Electronics Solutions has announced will showcase the newest advances in coating and resin technologies from its Electrolube brand at this year’s SMTconnect event in Nuremberg from 10-12 May.
The company will feature its eco-friendly range of bio-based conformal coatings and resins on Stand 125 in Hall 4, including fast-curing UV cure coatings and a high performance PU resin.
Solvent-free, bio-based conformal coating
The company says its advanced solvent-free, bio-based conformal coating UVCLX is first of its kind globally, and provides high levels of protection in a rapid processing time. “Applied via a selective coating machine, UVCLX has been created with 75% of the organic content obtained from renewable sources and exceeds traditional UV Cure Coatings by being touch dry after just a short exposure to LED-365nm UV light;” the company said. “[Unlike] traditional UV Cure Coatings, full cure is guaranteed in less than 24 hours due to its secondary chemical cure mechanism, which even cures shadowed areas in a matter of hours.
“[It] significantly improves production time and provides even higher levels of performance, including resistance to cracking during thermal shock cycling.”
Bio-based polyurethane resin
“The new bio-based polyurethane resin, UR5645 is a tough, two-part encapsulation system developed for the protection of electrical components in harsh environments,” the company said. “It features an excellent bio content of 63.33%. and is ideal for a wide range of applications including automotive and marine, due to its very low water absorption which enables continuous immersion in water at elevated temperatures and depth.”
It is a highly versatile resin with an operating temperature range of -50 to +150oC, (160oC for short excursions of 30 minutes dependent upon application and geometry) as well as being low viscosity – for a faster and more efficient potting process, the manufacturer explained. “It also provides excellent chemical resistance to acids, alkalis and fuels, ideally suited for the harshest conditions, such as those found in automotive applications.”
“Bio-based materials, obtained from biological resources (biomasses, feedstock, plants, and biological waste), deliver a viable and sustainable alternative to materials derived from petrochemicals, and at Electrolube, we will continue to innovate new bio-based alternatives that have significantly less impact on the environment and meet the ethical needs of manufacturers and end users,” the company said.
