Modified Silicone Conformal Coating

The RS Pro modified silicone conformal coating, specially formulated the protection of your electronic circuits. Once cured, it is resistant to a wide range of solvents, lubricants and cooling fluids putting your mind at ease. All models are highly reliable and excellent quality.

Features & Benefits

Excellent resistance to mould growth UV light and to prolonged tropical exposure/salt spray
Low oxygen permeability
Provides excellent in-service protection for circuitry and PCBs at a typical coating thickness of 0·025-0·05mm
Clear coating is approved to DEF STAN 59//47 issue 4 and UL 746C-QMJU2

Typical Applications

Protective coatings like this RS PRO conformal coating, is a thin polymeric film applied to a printed circuit board (PCB) in order to protect the board and its components from the environment and to prevent corrosion. The protective coating is designed to cover and protect solder joints, the leads of electronic components, exposed traces, and other metallised areas from corrosion, ultimately extending the working life of the PCB. Conformal coatings are used in many different types of applications where high performance and reliability are needed including.
Mobile electronics


Why do I need a Conformal Coating?
Printed circuit board performance can be affected due to moisture, chemicals, salt stray and temperature extremes. A protective coating can be used in order to protect printed circuit boards and their components and ultimately prevent corrosion and failure.

Types of Conformal Coatings

  • Silicone coatings give great protection in a wide range of temperatures, have good chemical resistance, flexibility and are resistant to sea salt.

  • Acrylic coatings are easy to use and remove, provide fair elasticity, are abrasion resistant and have a high dielectric strength.

  • Polyurethane coatings have excellent moisture and chemical resistance properties and are abrasion resistant.

  • Epoxy coatings give good humidity resistance, high abrasion and chemical resistance
