2K350 Two Part Conformal Coating
In Stock
K350 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.
