The protective lacquer Elpeguard SL 1800 FLZ from Peters has been awarded an extended UL certificate. In addition to the highest non-flammability level UL V-0, the UL 746 E rating now also certifies that the acrylate-based protective lacquer for printed circuit boards can be used outdoors.

"This means that the UL-certified product has received unrestricted outdoor approval," says Johannes Tekath, describing the value of what is now the third industry standard that the Elpeguard SL 1800 FLZ claims for itself. This is because the Peters product is also recommended for demanding electronics applications in the IPC CC 830 C and HK MS 941-04 standards as performance criteria for protective coatings, according to the Head of Research and Development at the Kempen-based coating manufacturer. The SL 1800 FLZ product range therefore meets the applicable standards and requirements with regard to potential risk from fire, electric shock and mechanical stress. The outdoor approval means that devices whose sensitive electronic components such as circuit boards are protected with Elpeguard SL 1800 FLZ can get wet for short periods without compromising safety and functionality. "This can be the case for hedge trimmers, lawn mowers or cordless screwdrivers, for example, which gardeners or roofers can use outdoors in the rain with confidence," says Johannes Tekath, describing the added value that UL approval brings.

"As a project partner, we have worked intensively with a customer to ensure that our protective coating now also meets these highest UL criteria," says Hartmut Giesen, who has been working in application technology at Peters since 2011. The customer's request was an incentive for Peters to also meet this third standard. "UL stands for Underwriters Laboratories Inc.", reports Hartmut Giesen, who is involved in coating technology and customer consulting for special coatings for PCB production and special technologies at Peters. The US-based testing authority that awards this label is the world's leading organization for the certification of materials, components and end products in the field of product safety of all kinds. The Elpeguard SL 1800 FLZ is still a relatively new Peters research product. "The further development of the Peters classic from the Elpeguard SL 1307 family of protective coatings can therefore be described as a success," says Peters Managing Director Ralf Schwartz, describing the added value for industrial customers. With the Elpeguard SL 1800 FLZ, the research and development team in Kempen has come up with a solution that is as forward-looking as it is practical. Ralf Schwartz: "The modified acrylate is likely to be more than ever the benchmark in the family of physically drying thin-film coatings on the world market.
