Enhanced protection for enhanced PCB performance
Conformal coatings are designed to protect printed circuit boards and related equipment from their environment. Typically applied at 25-75μm, 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 >
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.
Product code: Part A Code*: E2K850A5L
2K850 is the latest addition to the 2K range of solvent-free two-part polyurethane conformal coatings. 2K850 uses innovative technology to combine the 2K technology with a UV cure mechanism, giving 2K850 a faster processing time while still offering superb levels of protection. In addition to the UV cure, 2K850 has a consistent and reliable secondary chemical cure, even in shadow areas. In comparison to other single part UV conformal coatings, 2K850 is extremely efficient with a tack-free touch dry time of just a few minutes, and a full cure of just 24 hours, compared to the industry moisture cure average of about 8-14+ days or requiring an additional thermal process of 1 hour curing at 120°C.
2K850 also offers several other benefits over more traditional UV cure conformal coatings, with improved coverage giving more effective protection against harsh environments, and vastly improved resistance to cracking during thermal shock cycling.
As with the other 2K range of coatings, 2K850 has been carefully formulated to combine the protection and properties of an encapsulation resin, while keeping the ease of application of a conformal coating. Applied using specially designed applicators from both PVA (VPX-2KS) and Nordson Asymtek (Latest in the AM Range) on selective coating machines, it is applied more thickly than the average coating (200-400μm). 2K850 provides excellent coverage while its flexibility offers protection even around delicate components and over component edges.
Additionally Electrolube's 2K range, including 2K850 are hydrophobic coatings giving excellent water and moisture /condensation protection including salt mist. This makes it an excellent choice for automotive, aerospace and other tough electronic applications exposed to hash conditions.*Two part conformal coating system requires 2K850A5L as Part A, and 2KPB01L as Part B.
