1C49HVF

Silicone 1C49HVF

HumiSeal® 1C49HVF conformal coating is:

  • silicone based
  • very fast curing
  • fluoresces under UV light
  • room temperature, moisture cure
  • single component
  • high viscosity for high-builds

HumiSeal 1C49HVF conformal coating has:

  • No VOCs or solvent
  • excellent environmental resistance and moisture resistance
  • RoHS Directive 2011/65/EU compliant
  • recognized under UL file number E105698

Application of 1C49HVF Silicone 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

1C49HVF is designed for application without additional thinning. Solvents or other thinners should not be mixed with 1C49HVF.

Syringe Application

HumiSeal® 1C49HVF is designed to be applied by hand syringes or automated needle dispensing such as a PVA

FC100 needle valve, Asymtek SC-300 in monofilament mode or other automated dispensing equipment

Brushing

Uniformity of the film depends on the component density and the operator’s technique.
