Potential Uses
Protective coating for rigid and flexible circuit boards, connectors, electronic components, or sensors; fast tack-free cure, highly controlled volatility for use around relays and high-tolerance devices (HDD, DVD, CD).
Application Methods
Applied by spray, brush, flow or some automated pattern coating. May be dip coated with special precaustions.
Cure
Time to cure is dependent on several variables including the method of application, film thickness, temperature and humidity. Tack- free time in the data table gives an indication of typical times until surface is dry enough to handle. Cure time for full cure are indications of time needed to develop full physical properties such as durometer, tensile strength or adhesion. These times, including full cure time, can be significantly improved by introducing mild heat of 60 °C or less.
