Conformal Coatings

Enhanced protection for enhanced PCB performance

An Electrolube brand conformal coating product on printed circuit board undergoing UV cure.
  • UL, MIL and IPC-CC-830 approved
  • Solvent removable and solvent resistance coatings
  • Acrylic, Silicone, Polyurethane and Hybrid Materials
  • UV cure and water-based options available
  • UV trace to aid inspection
  • Thinners and masking products

Conformal coatings are designed to protect printed circuit boards and related equipment from their environment. Typically applied at 25-75μm, these coatings ‘conform’ to the contours of the board allowing for excellent protection and coverage, ultimately extending the working life of the PCB.

Electrolube is among the world’s foremost experts in the formulation and application of conformal coatings designed to meet international approvals (including European and American military specifications). The range of products currently available comprises acrylics, silicones, polyurethanes, hybrid chemistries and environmentally friendly options.

Electrolube can offer both transparent and pigmented coatings to improve or camouflage the appearance of printed circuit boards. The range also includes a number of ancillary products to complement the use of our conformal coatings, including thinners and removers, peelable coating masks and thixotropic materials for dam and fill applications.

Electrolubes Conformal Coatings Technical Director Phil Kinner recently wrote a micro e-book on conformal coatings for harsh environments. It’s a great little insight into the selection, implementation and testing of protective coating process.

HCS - Heat Cure Silicone Conformal Coating

Heat Cure Silicone Conformal Coating

5 Litre

Product code: HCS05L

HCS is a fast curing solvent free silicone conformal coating with 100% solids and is formulated to meet the requirements of UL94 V-0. It is a low viscosity coating which due to its silicone base is flexible with low stress on components whilst remaining tough enough to withstand abrasion.

It has a thermal fast-cure mechanism, achieving a full cure within just 10 minutes at 105°C. The solvent free formulation also ensures that there is little by-product from the cure maintaining a low odour system.

HCS also offers a wide operating temperature range of -65°C to +200°C which makes it especially suited to applications such as the automotive industry, power electronics or other electronic applications that require high temperature performance.

Key Properties:
  • Flexible coating, low stress on components
  • Meets requirements of UL94 V-0
  • Fast thermal full-cure (10 mins at 105°C)
  • Virtually no cure by-products, low odour
  • Good adhesion
  • Very wide operating temperature range
  • Good stability at high temperature.
  • REACH Compliant
  • RoHS Compliant
