Submit QuoteMiller-Stephenson ShieldSys™ Urethane Conformal Coatings provide superior toughness, abrasion resistance and excellent protection from humidity and organic solvents. Both ShieldSys™ 470X and 472X conformal coatings provide superior protection versus acrylic coatings and are strongly recommend where maximum protection from solvents and abrasion are needed.
Our exclusive polyurethane conformal coating resin conforms to MIL-I-46058C Type UR and IPC-CC-830 qualified and UL94 V-0. Available as either aerosol or bulk formulations. Both ShieldSys 470X and 472X are Single component conformal coatings, are easy to apply, and have long pot life but do require longer cure times. 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.
Benefits include: • Meets MIL-I-46058C Type UR • Superior Solvent and Abrasion Resistance • Easy to Apply • UV active for easy inspection • easily flows to hidden areas of board.
Urethane Conformal Coatings
ShieldSys™ 470X Polyurethane Conformal Coating is Miller-Stephenson's most advanced conformal coating, utilizing our exclusive high-density crosslinking polyurethane resin. This single-component, pre-catalyzed coating offers ease of application, and self-leveling properties ensuring the coating wets all areas of the board and cures to a smooth profile with predictable film thickness.
- Exclusive High-Density Polyurethane Conformal Coating
- Superior Toughness and Abrasion Resistance
- Solvent, Humidity, and Corrosion Resistant
- Base resin meets MIL-I-46058C Type UR
- IPC-CC-830 qualified and UL94 V-0
Urethane Conformal Coatings
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
Urethane Conformal Coatings
ShieldSys 472X offer superior printed circuit board (PCB) protection with a tough and solvent resistant Urethane conformal coating. The cured coating is repairable and can be easily applied via brush, dip or spray. Ideal for the assemblies require superior long-term protection or required to meet a MIL-Spec.
