This is based on room temperature curing conformal coating, acrylic modified resin and single component air drying. Conformal Coatings help protect printed circuit boards from environmental stresses, especially contaminants such as water, solvents, dust and other materials detrimental to electronic assemblies. It does give cost problems though - the PCB manufacturers HATE it because it gets into connectors.
