Seven next generation UV cure conformal coating products will be launched for the first time in Europe at the SMTConnect show In Nuremberg, hosted at the Nurnberg Messe from 07-09 May 2019. Electrolube, the global manufacturer of electro-chemicals, developed the exciting new UVCL range to meet the various requirements of electronics, LED and automotive manufacturers, with the additional benefit of rapidly increasing production time and offering even higher levels of performance. The new UV Cure range will be showcased in Hall 4, stand 339, where Electrolube’s senior technical team will be available to discuss the advantages and specifications of the new UV cure coating range.

Electrolube Launch Next Generation UV Cure Coatings

The UVCL range is solvent-free, VOC-free and provides unsurpassed performance in harsh environments, including resistance to cracking during thermal shock cycling. The main benefit of Electrolube’s UV Cure coatings is that boards can be handled immediately, with full cure guaranteed within 6-12 hours due to the chemical secondary cure mechanism. In comparison to existing UV cure systems on the market, the majority require minimum moisture secondary cure times of 8-14+ days, whereas the new UVCL range facilitates tremendous reductions in the amount of Work In Progress.

The range features UVCL, a single component, medium-low viscosity dual cure coating with secondary moisture cure, for complete cure in shadow areas. Available in 5L packaging, UVCL is VOC-free, non-flammable and demonstrates excellent electrical properties. The coating provides a wide operating temperature range and is ready to use for selective spray application.

UVCLP is the Plus version of UVCL. It is a transparent, flexible coating which is extremely resistant to thermal shock.  The main benefits of UVCLP are the improved coverage and protection achieved, along with a guaranteed chemical cure in 6 hours thanks to its unique secondary cure mechanism. Selectively applied at 50-150 microns thickness, the plus version will always afford a higher level of condensation protection than UVCL when sprayed at the same thickness. UVCLP has a higher maximum operating temperature of 150°C and meets the requirements of UL94V-0 at thicknesses below 150 microns and can be cured with either 365nm LED lamps or ‘D’ bulb microwave technology.

Electrolube have also developed an ‘xtra’ version of UVCL, called UVCLX, which shares the benefits of UVCLPwith excellent resistance to thermal shock, immediate board handling with a guaranteed chemical cure in 6 hours thanks to the unique secondary chemical cure mechanism and exceptional coverage and protection. Reflecting its environmental credentials as well as increasing the ease of inspection, UVCLX is a green-opaque coating that can be applied at up to 300 microns and has a higher maximum operating temperature of 150°C. It is a highly flexible coating that demonstrates excellent thermal conductivity 0.7 Wm-1K-1 for significantly improved heat dissipation. The coating is also UL746 qualified and meets the requirements of UL94V-0 at thicknesses below 300 microns.

Further UV Cure coating products will be launched at the show and include a brand new film coating product, UVCL-FC, which enables the application of even thinner coatings and faster curing line speeds.  UVCL-FC is a low viscosity, fast-curing UV formulation for rapid processing. The company will also showcase a new UV cure coating specifically for LED applications. The UVCL-LED coating is also a low viscosity coating that enables rapid cure with low energy 365nm LED lamps.

UVCL-HV is a high viscosity UV curable material, designed to provide better coverage of component leads and exposed metal surfaces during dispensing applications and Electrolube’s UVCL-Gel is a no-flow gel version of UVCL, designed for sealing connectors and other areas that must not be coated.

Ron Jakeman, Managing Director of Electrolube, comments, “The new UV cure coating range is an unbeatable range of conformal coating materials and we are very excited about launching the new range to the European market.”

UVCLP UV Cure Conformal Coating Plus

Electrolube UVCLP-05L_lge

UVCLP is a part of the new generation of UV cure conformal coatings developed by Electrolube to offer the highest levels of protection while maintaining a fast processing time. Applied using selective coating machine, UVCLP offers exceptional processing time compared to even other UV cure coatings. UVCLP is touch dry after just a short exposure to the correct wave length of UV light, with a full cure guaranteed in under 24 hours by virtue of the secondary chemical cure mechanism. The chemical cure ensures that even shadowed areas are fully cured in a matter of hours. This is in stark contrast to other traditional UV Cure Coatings that can require weeks for a complete cure; (some shadowed areas will even remain uncured). UVCLP therefore ensures reduced work in progress times.

UVCLP is optimally applied between 100-150μm achieving excellent edge coverage, even on sharp components ensuring the highest levels of protection are achieved even during temperature cycling and thermal shock.

To add to this UVCLP offers exceptional performance in harsh environments, its hydrophobic nature giving it excellent protection from moisture, salt mist and even full immersion for short periods with the option to extend this period by applying the coating in a thicker layer. UVCLP is also flame retardant meeting the criteria for UL94 V-0 when applied below 150μm and has good chemical and abrasion resistance.

Key Properties:

  • UV Cure Conformal Coating
  • Full cure in under 24 hours
  • Optimally applied at 100-150μm for ultimate protection
  • Excellent coverage, even over difficult geometries
  • Thermal Shock Resistant
  • Hydrophobic – Excellent moisture / water resistance
  • Good Chemical Resistance
  • Abrasion resistant
  • Transparent with UV Trace
  • Meets UL94 V-0 below 150μm
  • REACH Compliant
  • RoHS-2 Compliant

UVCLX UV Cure Conformal Coating Xtra

Electrolube UVCLX-05L_lge

UVCLX is part of the new generation of UV Cure Conformal Coatings developed by Electrolube to offer the highest levels of protection whilst maintaining a fast processing time. Applied via a selective coating machine, UVCLX builds on the speed of a traditional UV Cure Coating, being touch dry after just a short exposure to the correct wave length of UV light. A full cure is guaranteed in less than 24 hours by virtue of the secondary chemical cure mechanism. The chemical cure ensures that even shadowed areas are fully cured in a matter of hours. This is in stark contrast to other traditional UV Cure Coatings that can require weeks for a complete cure; (some shadowed areas will even remain uncured). UVCLX therefore ensures reduced work in progress times.

UVCLX is optimally applied at between 150-250μm achieving excellent edge coverage, even over sharp components. This ensures that UVCLX achieves the highest levels of protection, even during temperature cycling and thermal shock. UVCLX offers exceptional performance in harsh environments, its hydrophobic nature giving it excellent protection from moisture, salt mist and even full immersion for short periods and can be applied more thickly as required for such applications.
