GE TOSSEAL 817 is a one-component, semi-flowable, neutral cure silicone sealant that cures at room temperature on exposure to atmospheric moisture into a durable rubber.
It provides excellent adhesion to concrete and most construction materials, combined with superior resistance to high/low temperatures, water, ozone, and weathering.
With its extremely low modulus, TOSSEAL 817 minimizes strain on substrates, ensuring excellent recovery from joint compression and extension.
It is especially suitable for horizontal concrete joints subject to high movement, such as in roads, pavements, warehouses, and parking decks.
