Description
2K350 flame retardant conformal coating is a high performance two part and solvent-free coating. It is based on a polyurethane conformal coating which has been carefully formulated to combine the best protection and properties of an encapsulation resin, with the best properties of a conformal coating.
2K350 is formulated for application using specially designed applicators for selective coating machines from both PVA (VPX-2KS) and Nordson Asymtek (Latest in the AM Range). 2K350 is applied more thickly than the average coating (100-300μm), resulting in excellent edge coverage over component leads and packages.
2K350 offers enhanced thermal performance when compared to 2K500 with an operating range of -65 to +130°C while its extreme flexibility prevents cracking during thermal shock testing. It offers good chemical resistance and is a flame retardant conformal coating meeting UL94 V-0 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 and 2KPB0 as the reaction agent, please refer to the product TDS for recommended mix ratios.
