Current Trends in Conformal Coating

No matter what the request may be, from appearance to viscosity, to the cure mechanism or even changing the solvent carrier to a VOC friendly alternative, customizing formulations has become the norm more than the exception and chemical manufacturers are marketing these products as standard solutions. End users should always work with formulators to assure that any modification to the original chemistry does not affect performance properties such as adhesion, protection, or curing. From an application standpoint, having your chemistry slightly altered may affect a variety of process parameters so always consult your material manufacturer and applications staff prior to making any formulation change. In an automated process, the changes may be as simple as modifying the robot speed or adjusting the path spacing to compensate for the new flow characteristics, but these factors can always be prequalified in a test laboratory.
