Chemask Lead-Free Solder Masking Agent CLF8 is a temporary, fast curing, peelable solder masking agent formulated for use in high temperature lead-free applications. It is a temperature resistant coating that protects
component-free areas of the PCB during wave soldering. Chemask Lead-Free can be introduced into the preheat oven within 4 minutes of application without adverse effects. Use to protect pins, posts, contacts and edge connections during conformal coating processes.
FEATURES:
- Stable to 550°F (288°C)
- Can be used in lead-free or Tin/Lead applications
- Compatible with rosin, no clean, and water soluble fluxes
- Unaffected by cleaning solvents
- Leaves no residue – non-contaminating
- Ready for wave solder in 4 minutes
- Dries tack free in 15 minutes
TYPICAL APPLICATIONS: Chemask Lead-Free Solder Masking Agent CLF8 protects:
- Component Free Areas for Soldering
- Components and Sockets
- Pin Connectors During Soldering
- Temperature Sensitive Components During Wave Soldering
