The ELPEGUARD thick film coatings of the series Twin-Cure DSL 1600 E-FLZ are used to protect and insulate electronic assemblies so that they can fulfill higher requirements regarding reliability and service life. Owing to their very good resistance against moisture and condensation excellent protection against corrosion (such as electro-corrosion and migration) is possible even under harsh climatic conditions.
FEATURES:
- basis: copolymerize of polyurethane (UR) and polyacrylate (AR)
- solvent-free / VOC-free
- powerful protection through electrical insulation properties directly after UV curing
- chemical cross-linking reaction in shadow zones
- excellent mechanical and chemical resistance
- tested according to IPC-CC-830B and MIL-I-46058C
- UL-approval according to UL 94 (UL file No. E80315): best flame class V-0
- UL-approval of DSL 1600 E-FLZ/75 according to UL 746E (UL file No. E80315)
- temperature range of -65 to +130 °C [-85 to 266 °F]
- the lower the viscosity, the higher the elasticity, and the easier material tension can be lowered even under rapid and extreme thermal shocks
- depending on the coating thickness also suitable for coating flexible circuits (“flex-to install”, bending stress during assembly only)
- excellent edge coverage, wetting and underfilling of components (“micro-casting”), very good capillary-active behavior, yet not suitable as underfill material
- excellent adhesion
- halogen-free according to JPCA-ES01-2003 and IEC 61249-2-21
- high transparency and yellowing resistance
- DSL 1600 E/500 is especially suitable for lighting electronics
- when applied in thick layers, components may be fixed to protect against vibration
- can be mechanically stripped for repair purposes (blasting method).
