HumiSeal 1A33NS is a single component, toluene-free, polyurethane conformal coating suitable for general printed circuit board applications.

Product Information

HumiSeal 1A33NS conformal coating is:

  • urethane chemistry
  • toluene free
  • chemically resistant
  • single component
  • contains no free isocyanates
  • RoHS directive 2015/863/EU
  • Recognized under UL File Number E105698

HumiSeal 1A33NS conformal coating has:

  • excellent moisture and environmental protection for printed circuit assemblies
  • fluorescence under UV light for ease of inspection

Application of 1A33NS Conformal Coating

Conformal coatings can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue “no clean” materials. Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level.

Dipping

Depending on the complexity, density and configuration of components on the assembly, it may be necessary to reduce the viscosity of HumiSeal 1A33NS with HumiSeal Thinner 521 in order to obtain a uniform film. Once optimum viscosity is determined, a controlled rate of immersion and withdrawal (typically, 5 to 15 cm/min) will further ensure even deposition of the coating and provide a uniform film. During application, evaporation of solvent causes an increase in viscosity that should be adjusted by adding small amounts of HumiSeal® Thinner 521. Viscosity in the dip tank should be checked regularly using a simple measuring device, such as a Zahn or Ford viscosity cup.
