High Performance Silicone Conformal Coating | ShieldSys™ 462S

Ultra-High Performance Conformal Coating, Self-Priming Abrasion Resistant Coating, Flexible and Transparent

ShieldSys™ 462S High Performance Silicone Conformal Coating is an exclusive Miller-Stephenson electronic coating designed to be a one-part, self priming coating that offers superior moisture and corrosion resistance in a highly flexible, high durameter coating. Ideally applied to flexible or rigid board, ShieldSys™ 462S is formulated to provide superior self-levelling and ease of application regardless of application method. Leverage our proprietary silicone resin with nano-ceramic adhesion promotors, ShieldSys 462S will provide excellent adhesion and coverage regardless of your board configuration, allowing greater design freedom and process flexibility, making this an excellent, future-proof solution. Benefits of ShieldSys 462S High Performance Silicone Conformal Coating:

• High Performance Silicone Conformal Coating
• Excellent Thermal and Abrasion Resistance
• Ideal for High Vibration, High Moisture, or Heat Challenged PCBs
• Superior Self-Levelling and Excellent Flow-out
• One-Part, Self-Priming, Room Temperature Cure System
• Fast Tack-free timeframe ( 5 – 7 minutes @ RT)
• Base Resin Conforms to UL 746C MIL-1-46058C

ShieldSys™ 462S High Performance Silicone Conformal Coating utilizes Miller-Stephenson next-generation coating technology leveraging our proprietary self-levelling and adhesion promoting components, offering customers significantly simpler and forgiving application flexibility. Unlike other high solids coatings, ShieldSys™ 462S is considerably easier to apply thanks to optimized viscosity, carrier solvents, and tailored evaporation rate.  This results in a coating which delivery exceptional quality in all application methods including: dipping or flood coating, manual and automated spraying, and re-work applications. Moreover the applied coating has excellent reparability because they can be removed from substrates and circuitry by scraping or cutting, or by using solvents or stripping agents. If only one circuit component is to be replaced, a soldering iron may be applied directly through the coating to remove the component.

ShieldSys™ 462S High Performance Silicone Conformal Coating – Superior Flexibility and Abrasion, Excellent Temperature Stability, Room Temp Cure – a potent combination

Designed from inception to leverage Miller-Stephenson next-generation silicone conformal coating chemistry with superior application ease and robust cured film properties, ShieldSys™ 462S High Performance Silicone Conformal Coating provides a categorical improvement in PCB protective coatings.  Our high solids formulation provides consistent film build in fewer coatings, faster processing speeds and rapid tack free times (5-7 minutes) allowing customer to process boards faster without sacrificing reliability or consistency. The cured film offers a tough high durometer and abrasive resistant RTV film that is both highly flexible and clear.
