Durashield V42 Heavy Copper Dielectric

Durashield V42 Mono Filler is a UV-sensitive product designed as a trench-filler for thick copper printed circuit boards. Available as a single-component Monofiller or as a two-component; the formulation is acrylate-based, 100% solids and 100%-curable.

Durashield V42 Filler is characterised by exceptional:

  • Through-cure
  • Flexibility
  • Adhesion to copper, epoxy and resin-interlayer substrates.
  • Thermal shock & solder resistance in lead-free, high temperature application

Durashield V42 Thermal Cure Epoxy Mask

Durashield V 42 Mask is a low VOC, thermally-curable coating designed to act as the soldermask finish for thick copper circuitry planarised with Durashield V42 Filler.

Two-pack epoxy chemistry is employed to give excellent adhesion to bare copper & epoxy-based surfaces. Durashield V42 Mask exhibits good hot hardness, resistance to surface damage and excellent resistance to all multiple soldering processes, including lead free soldering. These features are combined with outstanding flexibility.

Durashield V42 Mask Coatings may be cured using a thermal convection or infrared heat source and Durashield V42 Mask has passed the IEC 68-2-38 Z/AD composite temperature/humidity cyclic test on 400 micron copper circuitry.
