StenSeal® SI 111 is a single-component, cold-applied, non-sagging, low-modulus silicone joint sealant formulated specifically for outdoor concrete pavements. Its non-sagging body stays in place during application on sloped, vertical, and irregular joints, while its low hardness and high elongation absorb dynamic movement under heavy traffic, jet blast, and intermittent chemical contact. It delivers long-lasting resistance to fuels, hydraulic fluids, oils, UV radiation, and extreme temperatures. StenSeal® SI 111 is fully compliant with ASTM D 5893 Type NS, ASTM C 920 Type S, Grade NS, Movement Class 100, and EN 14188-2 System S, Class A, Type NS; compliance with ASTM D 5893 has been certified by PRI.
Areas of Use
StenSeal® SI 111 is ideal for joints and cracks with irregular cross-sections or variable width, as well as sloped and vertical joints. It performs well in the joints of airports, roads, bridges, refineries, and chemical facilities, as well as in expansion and contraction joints of asphalt or cement concrete pavements. It adheres to properly prepared joints without a primer. For constant-width horizontal concrete joints with straight edges, the self-leveling StenSeal® SI 110 is more suitable.
