Henkel announces the commercialization of Loctite Stycast CC 8555. It is a conformal coating designed to protect electronics in extreme environments. Loctite Stycast CC 8555 delivers printed circuit board (PCB) and sensitive component protection in challenging, high-power applications. This includes motor drives, PLCs and EV charging infrastructure. It also includes AC/DC power supplies and other high-voltage electronics.
Safeguarding Against Corrosion
Loctite Stycast CC 8555 meets the most stringent requirements for rugged safeguarding against corrosive conditions. This includes moisture, mixed gases and various chemicals. It has a relative temperature index (RTI) rating of 130° C per the UL 746E standard. It also has a UL 94 V0 flammability rating and meets IPC-CC-830 requirements.
Defending electronics from potentially damaging environmental impacts is essential. It would be for 24/7/365 industrial equipment, power conversion systems and alternative energy infrastructure. This is where reliability and longevity are expected.
In addition to its safety and reliability credentials, Loctite Stycast CC 8555 enables robust electrical performance. It offers process simplicity. It is cost-competitive compared to solvent-based formulations. The new conformal coating has an excellent dielectric strength of 27.5 kilovolts per millimeter (kV/mm). It also has good surface insulation resistance (SIR) to protect electrical functionality.
When it comes to processability, Loctite Stycast CC 8555 also stands out. The material has a wide process window. It delivers good wetting, flow and leveling performance. It ensures fast, thorough coverage of PCBs and sensitive components with no voiding or visible defects.
“
High-power electronics are integral to industrial manufacturing, human mobility and comfort and global energy production. These systems must adhere to the highest reliability and safety standards. Protecting electronics is vital to their dependable function and longevity,” said Justin Kolbe. He is the director of Market Strategy for Power and Industrial Automation at Henkel.
Fast UV-curing
Curing is achieved quickly, with primary UV cure occurring in seconds. It is followed by a moisture cure for shadowed areas. High processing speed and the elimination of heat-induced curing also contribute to Loctite Stycast CC 8555’s low total cost of ownership.
“
Conformal coatings are the go-to protective material for nearly all PCBs used in power electronics. And Henkel’s latest formulation rises above. It delivers on the reliability requirements foremost. It is also easy to use, cost-effective and is a lower-impact material. Loctite Stycast CC 8555 covers all the bases and then some,” continued Kolbe.
“
Loctite Stycast CC 8555’s VOC- and solvent-free formulation answers the call for environmental concerns. It provides significantly lower cost from a surface area perspective,” explained Kolbe. “
With solvent-borne conformal coatings, three to four times the weight must be deposited to achieve the same thickness as non-solvent-based materials.”
“
This means Loctite Stycast CC 8555 can provide exceptional protection with one-third to one-half of the sprayed volume of a solvent-based system,” added Kolbe. “
Users get lower total cost, environmental volatiles reduction, energy-saving curing, and superior performance. That’s a hard combination to beat!”
