Printed circuit boards (PCBs) form the foundation for electronics in
communications and industrial
and energy applications. 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 but flexible silicone technology, Dow Corning’s
conformal coatings promote extended service life and enhanced reliability for
your PCB components and assemblies. 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 – from -45°C to 200°C.
Silicone conformal coatings from Dow Corning fall into two
One-part moisture-cure solutions encompass room-temperature
vulcanized (RTV) elastomeric or elastoplastic coatings.
RTV elastomer coatings protect delicate electronic
architectures from environmental contamination and mechanical stress. Higher
viscosity grades are suitable for pin/solder joint coverage and thin-section
RTV elastoplastic coatings deliver tough, resilient,
abrasion and moisture resistance against various forms of contamination, and
many carry recognition from Underwriter
Laboratories , Mil Spec and IPC-CC-830. They are appropriate for rigid and
flexible PCBs, ceramic and hybrid circuits and other components.
Heat-cure conformal coatings: cure in minutes to yield a
transparent, flexible elastomeric film suitable for low-stress protection of
PCBs with delicate, finer architectures. They are compatible with industry
standard high-speed production of rigid and flexible PCBs.
After cure, Dow Corning’s silicone coatings 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
electronic printed wiring board applications.
Available in a variety of viscosities and cure chemistries, Dow Corning
provide excellent unprimed adhesion to many substrates, including ceramics,
metals, glass and filled plastics. Unlike competitive materials, many of our
silicone coatings contain little or no solvents, minimizing the need for
special storage, handling or ventilation.
