SS-38 is a peelable silicone RTV rubber developed for applications requiring
a form fitting temporary protective cover. SS-38 is a 1-Part silicone adhesive
that when applied to the substrate, cures to a pliable, removable, protective
covering within a day. When cured, the elastomer resists weathering, ozone,
moisture, UV and high temperatures. SS-38 works well in automatic and manual
dispensing equipment.
