Features

N/A
Cures to tough, resilient, abrasion-resistant surface; solvent-borne resin coating with much lower odor; reduced VOC content as measured by certain U.S. state standards; more environmentally and worker friendly; room-temperature cure with optional heat acceleration after solvent flash-off; UV indicator for inspection; UL V-0 flammability rating; IPC-CC-830 tested; Mil Spec 46058C tested

Potential Uses

N/A
Protective coating for rigid and flexible circuit boards. These one-part, self-priming coatings cure to flexible, transparent elastoplastic coatings ideally suited for electronic printed wiring board (PWB) applications, particularly those requiring toughness and abrasion resistance.

Application Methods

N/A
Applied by spray, brush, flow, dip or automated pattern coating. For spraying operations, solvent dilution of up to 60 % is recommended. For dip coating operations, material may be used as supplied or solvent diluted if a thinner film build is desired. Care should be taken to ensure the solvent is free from moisture and dip tanks should be covered when not in use. For dilution of low VOC coatings, Dow OS-20 Fluid is recommended.

Cure

N/A
The time required to reach a tack-free state can be reduced with heat. When using heat for this purpose, allow adequate time for the solvent to evaporate prior to exposing to elevated temperatures in an air circulating oven. A typical cure schedule for 3 mil (75 micron) coatings is 10 minutes at room temperature, followed by 10 minutes at 80 °C. If the coating blisters or contains bubbles, allow additional time at room temperature for the solvent to flash off prior to oven cure.
