PROCESS RECOMMENDATION
APPLICATION
AVR80 BA can be sprayed, dipped or brushed. The thickness of the coating depends on the method of application, but a dip coater normally deposits a film thickness of about 25 microns (single coat). Workshop temperatures of less than 16°C or relative humidities in excess of 75% are unsuitable for the application of AVR80 BA.
Before applying the printed circuit board must be clean, dry and free of moisture. Pcbs are humidity sensitive, it is important to remove it before coating application. A stage in an oven for 4 hours at 80°C is usually sufficient.
When cleaning before coating is required, Inventec is the prefect partner to find the right solution.
CURING
AVR80 BA will be touch dry after 15 – 20 minutes at room temperature and does not require thermal curing. The full properties will be obtained after a 24 hours at room temperature.
