AFA-G is a more viscous / gel like version of the successful AFA acrylic conformal coating. It has been designed to be used alongside the other AFA coatings. AFA-G is intended to be dispensed around the base of connectors to act as a permanent masking material. This masking layer will help prevent the capillary flow of material into the connectors, which can cause loss insulation of tabs and loss of connectivity. In addition, the improved resistance to flow of AFA-G can be used to more clearly define difficult keep-out areas during selective coating. . It can also be used to re-enforce sharp edges of critical components which may otherwise be missed by less viscous materials during the coating process.
Available in a Nordson EFD 30ml syringe, it can be applied by hand, as well as with automatic dispensing equipment.
As it is based on AFA, its properties as a conformal coating are much the same as the AFA coating range which includes being free of aromatic solvents making it less harmful to the environment and the operator. It has a fast touch-dry time and excellent adhesion to most substrates while providing outstanding protection against humidity and salt mist.
