POWERSIL® Insulator Finish

1 of 35 products in this brand
POWERSIL® Insulator Finish is a self-leveling, one-component silicone rubber that cures at room temperature under the influence of moisture in the air. This elastomer exhibits good mechanical properties and very good electrical properties, making it suitable for insulating applications. It utilizes an acetic acid-curing system and demonstrates excellent resistance to weathering and air pollution.
