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: Part A Code*: 2K5005L
2K500 is a hard, two-part polyurethane conformal coating system which provides the protection properties of an encapsulation resin, with the ease of application of a conformal coating and without the use of harmful solvents. It can be easily applied to provide excellent coverage, even areas with difficult geometries and maintains clarity even after prolonged exposure to UV light.
It is more abrasion resistant than 2K100 or 2K300 and has a wider operating temperature range providing protection for electronics exposed to temperature over a long period of time, as well as providing excellent thermal shock resistance.
2K500 is applied using selective coating machines from PVA (using the specially adapted part VPX-2KS) and Nordson Asymtek (using the latest in the AM range).
*Two Part System requires 2K500 as Part A and 2KPB01L as Part B, please refer to the product TDS for recommended mix ratios.
