HumiSeal 1B73 EPA is a fast drying, single component, acrylic conformal coating intended for use on printed circuit assemblies.

Product Information

HumiSeal 1B73EPA demonstrates excellent flexibility, fluoresces under UV light for ease of inspection and is easily repaired. HumiSeal 1B73EPA coating is MIL-I-46058C qualified, IPC-CC-830, RoHS Directive 2011/65/EU and EPA 33/50 compliant, and recognized under UL File Number E105698.

HumiSeal 1B31 EPA conformal coating is:

  • an acrylic chemistry
  • fast drying
  • single component

HumiSeal 1B31 EPA conformal coating has:

  • excellent moisture and environmental protection for printed circuit assemblies
  • fluorescence under UV light for ease of inspection
  • reworkability with ease
  • MIL-I-46058C qualification
  • IPC-CC-830 compliance
  • RoHS directive 2015/863/EU

Application of 1B31 EPA 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. Please contact a HumiSeal representative for additional information.

Dipping 

Depending on the complexity, density and configuration of components on the assembly, it may be necessary to reduce the viscosity of HumiSeal 1B31 EPA with HumiSeal Thinner 600 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 600 or 604. Viscosity in the dip tank should be checked regularly using a simple measuring device, such as a Zahn or Ford viscosity cup.

Spraying

HumiSeal 1B31 EPA can be sprayed using conventional spraying equipment. Spraying should be done in an environment with adequate ventilation so that vapor and mist are carried away from the operator. The addition of HumiSeal Thinner 600 or 604 is necessary to ensure a uniform spray pattern resulting in a pinhole-free film. The amount of thinner and spray pressure will depend on the specific type of spray equipment and operator technique. The recommended ratio of HumiSeal 1B31 EPA to HumiSeal Thinner 600 or 604 is 1:1 by volume; however, the ratio may need to be adjusted to obtain a uniform coating.

Brushing

HumiSeal 1B31 EPA may be brushed with a small addition of HumiSeal Thinner 600 or 604. Uniformity of the film depends on the component density and operator technique.
