Potential Uses

N/A
Protective coating for rigid and flexible circuit boards. These heat cure, one-part, self-priming coatings cure to flexible, transparent elastomers ideally suited for electronic printed wiring board (PWB) applications, particularly those employing sensitive components and fine pitch designs.

Application Methods

N/A
Applied by dip, spray, brush, flow or automated pattern coating. The stable bath life of these materials makes them ideal for dip coating applications.

Cure

N/A
Time to cure is dependent on film thickness, type of oven, and board population density. Heat cure time in the data table gives an indication of typical times after the coating is heated to the temperature indicated. Highly populated, large, heavy boards may take longer than the indicated times due to the large thermal mass taking extra time to warm.
