MOISTURE, CHEMICALS, SALT SPRAY, CORROSION, THERMAL EXPANSION, DUST, and ORGANIC GROWTH can cause damage to circuitry. Components will fail and costly maintenance will be required. The solution is Protect-R-Shield, the optically clear silicone elastomer conformal coating.
Protect-R-Shield offers maximum protection and clarity for LED applications and printed circuit boards. Third-party testing proves the consistent non-yellowing clarity of the Protect-R-Shield coating through thermal cycling, heat, humidity aging, and UV exposure.

Protect-R-Shield is a unique one part optically clear silicone elastomer which has been developed specifically for use as a conformal coating on LED and printed circuit boards. It does not have any VOCs and is extremely friendly to the environment. PRS has patented properties allowing the coating to be completely applied over the LEDs and circuit boards to form a highly effective and protective shield resulting in maximum protection from the elements and contaminants. The PRS conformal coating is selectively applied by computer robotic control.
Protect-R-Shield is a crystal clear elastomeric coating material that is formulated to offer outstanding insulation performance over a wide range of temperature (-65°C to 200°C). The material exhibits excellent adhesion to most printed circuit board substrates including metal core and Fr4. Protect-R-Shield will not yellow or break down from UV over time and exposure to an outdoor environment. PRS offers excellent flexibility and coefficient of thermal expansion/contraction.
