Chemask NA Non-Ammoniated Solder Masking Agent is a fast curing, peelable temporary spot mask formulated for safe use on sensitive metals. It contains high-temperature resistant
compounds that protect component-free areas during wave soldering. Chemask NA may be used to protect pins, posts, contacts and edge connections in the solder reflow oven or during conformal coating processes.

FEATURES:

  • Stable to 550°F (288°C)
  • For lead-free or tin/lead processes
  • Phthalate-free, low toxicity and environmentally safe
  • Compatible with rosin, water soluble fluxes and cleaning solvents
  • Dries tack free in 15 minutes
  • Goes straight into the pre-heat oven
  • Removes easily and leaves no residue
  • Non-contaminating, non-staining and non-corrosive
  • Compatible with gold, copper, nickel, silver and OSP finishes
  • RoHS compliant

APPLICATIONS:

Chemask NA protects:

  • Component-free areas during wave and reflow soldering
  • Components and pin connectors
  • Temperature sensitive components during wave or reflow soldering
  • Component Free Areas, Components, Pin Connectors, Temperature Sensitive Components, SMT
