RUBBERSTOP is a one-part, neutral-cure silicone sealant that does not stain or corrode exterior substrates. It exhibits good adhesion (without using a primer) to most building materials, such as galvanized iron, PVC gutters, glass, tiles, ceramics, enamel, aluminum, steel, zinc, and copper. With its permanently flexible silicone rubber property, it provides outstanding weather resistance and durability.
