Product Description
Chemtronics CLF1 Lead-Free Solder Masking Agent 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. It is used to protect pins, posts, contacts, and edge connections during conformal coating processes.
- 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
- RoHS compliant
Typical Applications of Chemtronics CLF1 Lead-Free Solder Masking Agent
Chemtronics CLF1 Lead-Free Solder Masking Agent protects:
- Component-free areas for soldering
- Components and sockets
- Pin connectors during soldering
- Temperature-sensitive components during wave soldering
