Silicone Solutions SS-18

Silicone Solutions SS-18 is a fast curing silicone RTV adhesive developed for applications requiring fast deep section cures as well as excellent adhesion. SS-18 is a 2-part, 1:1 mix ratio silicone that when ixed and applied to the substrate, allows handling within minutes. When cured, the elastomer resists weathering, ozone, moisture, UV and high temperatures. SS-18 works well in static mix dispensing equipment.
