Easily Processed Coatings for Higher Reliability
Printed circuit boards (PCBs) form the foundation for many applications in automotive, consumer devices, communications and industrial and energy. Yet these PCBs are often exposed to damaging environmental factors, ranging from moisture, dust and harsh chemicals to extreme thermal cycling and vibration.
Formulated from tough yet flexible silicone technology, Dow Consumer Solutions conformal coatings promote extended service life and enhanced reliability for your PCB components and assemblies – as they’ve done for decades.
Silicone conformal coatings offer several valuable benefits over alternative solutions.
- Greater Thermal Stability - Silicones perform reliably at sustained temperatures of as low as -45°C and as high as 200°C – and don’t degrade at such extreme temperatures. Many silicones can even withstand brief exposure to temperatures up to 250°C.
- Stress Relief - Silicone conformal coatings offer an extraordinarily broad range of durometers, as well as extremely low modulus options. That means they deliver better stress relief on delicate board components during thermal cycling.
- Simple Solvent-free Options - Silicones are nearly all solventless, making them the material of choice where emerging regulations impose complex and costly special requirements for handling and processing.
Our industry-leading solutions have delivered proven protection for decades against moisture, service environment and a variety of harsh operating conditions including a wide range of temperatures.
Available in a variety of viscosities and cure chemistries, Dow Consumer Solutions provide excellent unprimed adhesion to many substrates, including ceramics, metals, glass and filled plastics.
After cure, silicone coatings from Dow Consumer Solutions deliver dependable, long-lasting protection. Their natural elasticity also helps minimize mechanical or thermal stress on delicate component leads. Additional select grades deliver tougher, more abrasion resistant coatings ideally suited for printed circuit board applications.
To protect large components or thin sensitive wires or solder joints, our encapsulants offer better protection and faster, simpler cure options. For applications subject to thermal cycling, our silicone gels provide a flexible, almost fluid dielectric coating.
