MacDermid Alpha Electronics Solutions Conformal Coating Solutions for PCBAs Electrolube ® UVFlex

Product Overview Electrolube® UVFlex is a next-generation, solvent-free, UV-curable conformal coating engineered for demanding electronics applications. Its unique elasticity helps maintain coating integrity through extreme thermal cycling and harsh environmental conditions, delivering outstanding protection for electronic assemblies. The advanced coating technology provides significantly higher surface insulation resistance (SIR) and enhanced compatibility with leading no-clean solder pastes compared with conventional UV-curable coatings, helping maintain reliable protection throughout product operation in the field. Designed to protect against condensation and corrosive atmospheres, the coating chemistry combines superior performance with improved sustainability. Containing 25–30% bio-based content, UVFlex offers a more sustainable solution without compromise, extending the service life and reliability of electronic circuit boards operating in the most demanding environments. Product Features Solvent-Free, Fast-Cure Processing Urethane acrylate chemistry with UV cure in seconds and secondary moisture cure (RTV) for shadowed areas. ~100% solids formulation that is solvent-free, silicone-free, and PFAS-free. Exceptional Thermal Cycling Performance Long-lasting high elongation and elasticity help maintain coating integrity through thermal shock and extreme thermal cycling. Low modulus below -40°C and high-temperature stability help maintain protection across a wide operating temperature range of -65°C to +150°C. Enhanced Edge Coverage Thixotropic formulation improves component and edge coverage, as well as high surface insulation resistance (SIR) in damp heat (85°C/85% RH >10 GΩ) and condensation environments. Supports Long-Term System Reliability Improved compatibility with no-clean solder paste helps support overall system reliability throughout product operation. Sustainable by Design Increased protection helps extend product lifetimes, while 25–30% bio-based content contributes to a more sustainable solution. Flame-Retardant Protection Designed to meet UL 94 V-0 requirements (approval pending).
