UV Curable (Type AR/UR)

UV Curable Conformal Coatings(Type AR/UR)

HumiSeal’s UV curable conformal coatings represent an exciting innovation that provides superior performance. When combined with extremely fast curing, allows for short cycle times and maximum production speeds. These products can be sprayed using traditional automated spray equipment with the relatively simple addition of a small-footprint UV light curing unit.

HumiSeal has developed a range of UV curable coatings that are unique within the industry which include:

  • 100% solids, with minimal environmental impact
  •  Superb adhesion to a wide range of commonly used solder resists
  • High IR (insulation resistance) and MIR (moisture insulation resistance)
  • Resistance to a wide range of solvents
  • Great flexibility at a wide range of temperatures
  • Secondary moisture cure mechanism for shadowed areas
