Enhanced protection for enhanced PCB performance
Conformal coatings are designed to protect printed circuit boards and related equipment from their environment. Typically applied at 25-75m, these coatings conform to the contours of the board allowing for excellent protection and coverage, ultimately extending the working life of the PCB.More info > Download product selector chart > Download product brochure >
The use of conformal coatings is particularly important in automotive, military, aerospace, marine, lighting, industrial and green energy applications. Due to the rapid expansion of the electronics industry, conformal coatings are also finding their way into the domestic and mobile electronics industries, providing the necessary combination of high performance and reliability within a vast array of electronic devices.
Conformal coatings can be used in a wide range of environments to protect printed circuit boards from moisture, salt spray, chemicals and temperature extremes in order to prevent corrosion, mould growth and electrical failures, for example. The protection provided by conformal coatings allows for higher power and closer track spacing, in turn enabling designers to meet the demands of miniaturisation and reliability.
Electrolube is among the world's foremost experts in the formulation and application of conformal coatings designed to meet international approvals (including European and American military specifications). The range of products currently available comprises acrylics, silicones, polyurethanes, hybrid chemistries and environmentally friendly options.
Electrolube can offer both transparent and pigmented coatings to improve or camouflage the appearance of printed circuit boards. The range also includes a number of ancillary products to complement the use of our conformal coatings, including thinners and removers, peelable coating masks and thixotropic materials for dam and fill applications.
Electrolubes Conformal Coatings Technical Director Phil Kinner recently wrote a micro e-book on conformal coatings for harsh environments. It's a great little insight into the selection, implementation and testing of protective coating process.
Product code: DCA200H - DCA01L - DCA05L
DCA is a unique modified alkyd conformal coating specifically formulated to meet the highest defence standards in both Europe and the United States. Based on silicone, it is a highly flexible coating making it ideal for small or delicate components, while also maintaining protection through an extremely wide operating temperature range. DCA provides excellent chemical resistance to a wide range of chemicals and solvents such as those found in the automotive and aerospace industries making it an excellent choice for these industries.
DCA can be sprayed, dipped or brushed and DCA contains a UV trace, which allows inspection of the PCB after coating to ensure complete and even coverage; the stronger the reflected UV light, the thicker the coating layer is. UV light in the region of 375nm should be used for inspection.
