Urethane Conformal Coatings

- PRODUCT LIST

Urethane Conformal Coating provide superior toughness and abrasion resistance and excellent protection from humidity and organic solvents. Polyurethane coatings are available as either aerosol or bulk formulations. Both formulations provide excellent humidity resistance and far greater chemical resistance than Acrylic coatings. Single component Polyurethanes, are easy to apply, enjoy long pot life but sometimes require very lengthy cure cycles to achieve full or optimum cure. The cure cycle can be accelerated by the application of heat typically reducing cure times to less than 4-5 hours at 50% humidity. For applications that will see any direct mechanical wear against the coating users should consider urethane conformal coatings. Includes an ultraviolet (UV) indicator.

Miller-Stephenson’s Urethane Conformal Coating contain no free isocyanates and all formulations are 100% non-flammable, low odor, low VOC, and non-ozone depleting.

ShieldSys™ 470 Polyurethane Conformal Coating is Miller-Stephenson's most advanced conformal coating, utilizing our exclusive surface activation chemistry and high-density crosslinking polyurethane resin, ShieldSys 470 represents a substantial advancement in PCB coating technology. The single component, pre-catalyzed coating offers ease of application both with robotics or manual spray equipment and the self-levelling properties will ensure the coating wets all areas of the board and cures to a smooth profile with predictable film thickness.

  • Exclusive High-Density Crosslinking Technology
  • Superior Toughness and Abrasion Resistance
  • Solvent, Humidity and Corrosion Resistant
  • Reworkable and Room Temperature Cure
  • Exceptional Dielectric Properties
  • No Cracking or Crazing with Vibration

Urethane Coating | MS-472C

Miller-Stephenson’s Urethane Conformal Coating offers superior toughness and abrasion resistance and excellent protection from humidity and organic solvents. Urethane resins are very hard and resistant to mechanical wear, their hardness is second only to epoxy conformal coatings. However urethanes are much easier to be reworked than an epoxy. Miller-Stephenson’s Urethane Conformal Coating have the following benefits:

  • Reworkable and room temperature cure
  • Solvent and discoloration resistant
  • Fluorescent under UV light
  • No cracking or crazing with vibration
  • Superior toughness and abrasion resistance
