Directions for Use
DCB can be sprayed, dipped or brushed. The thickness of the coating depends on the method of application
(typically 25-75 microns). Temperatures of less than 16°C or relative humidity in excess of 75% are unsuitable
for the application of DCB. As is the case for all solvent based conformal coatings, adequate extraction should
be used (refer to MSDS for further information).
Substrates should be thoroughly cleaned before coating. This is required to ensure that satisfactory adhesion to
the substrate is achieved. Also, all flux residues must be removed as they may become corrosive if left on the
PCB. Electrolube manufacture a range of cleaning products using both hydrocarbon solvent and aqueous
technology. Electrolube cleaning products produce results within Military specification.
Spraying – Bulk
DCB needs to be diluted with the appropriate thinners (DCT) before spraying. In addition, DCB should be stirred
thoroughly allowing for air bubbles to disperse before application. The optimum viscosity to give coating quality
and thickness depends on the spray equipment and conditions, but normally a dilution ratio of around 1:1
(DCB:DCT) is required. Suitable spray viscosity is typically 50-80mPa s.
DCB is suitable both for use in manual spray guns and selective coating equipment. The selected nozzle should
enable a suitable even spray to be applied in addition to suiting the prevailing viscosity. The normal spray gun
pressure required is 274 to 413 kPa (40 – 60 lbs/sq.inch). After spraying, the boards should be placed in an air-
circulating drying cabinet following the curing schedule highlighted on page 4.
