The conformal coating PETERS ELPEGUARD® SL 1307 FL-T is a physically drying 1-pack conformal coating based on modified acrylate resins.
The colorless transparent, fluorescent conformal coating ELPEGUARD® SL 1307 FLZ-T is an ultra-thixotropic adjustment of the conformal coating ELPEGUARD® SL 1307 FLZ/2 which can be easily and precisely applied by means of a dispenser. This way, dams can be built around connectors, components, and pads to prevent the penetration or spreading of a subsequently applied conformal coating (dam and fill). The liquid flow after application ensures that component leads are completely surrounded.
The conformal coating ELPEGUARD® SL 1307 FLZ-T can be removed with the thinner V 1307 FLZ/2 for repair purposes and reapplied later.
FEATURES:
- Due to the ultra-thixotropic adjustment, ideal for dispenser application of dams to limit the application area of a subsequent conformal coating (dam and fill)
- Due to the special solvent composition virtually no risk of incipient dissolution of components and marking inks
- Very good ageing and yellowing resistance
- Protects against corrosion on account of the good resistance to moisture and condensation
- Can be completely removed by means of the thinner V 1307 FLZ/2 for repair purposes.
- ROHS
- Meets requirements per IPC-CC-830B
