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*: 2K3505L
2K350 is a flame-retardent, solvent-free two-part polyurethane conformal coating. It has been carefully formulated to combine the protection and properties of an encapsulation resin, while keeping the ease of application of a conformal coating.
2K350 is formulated for application using specially designed applicators from both PVA (VPX-2KS) and Nordson Asymtek (Latest in the AM Range) selective coating machines. 2K350 is applied more thickly than the average coating (100-300μm), it provides excellent coverage over component leads and packages, while its extreme flexibility prevents cracking during thermal shock testing.
2K350 offers enhanced thermal performance when compared to the general purpose 2K100 with an operating range of -65 to +130°C while still offering good chemical resistance and meeting UL94 V-0 flame retardant requirements.
As with the other 2K range of conformal coatings 2K350 is a hydrophobic coating which gives excellent water and moisture protection including salt mists making it an excellent choice for automotive electronics as well as other tough outdoor applications.
*Two Part System requires 2K350 as Part A and 2KPB01L as Part B, please refer to the product TDS for recommended mix ratios.
