When it came time to build a new parking structure at the Louisville International Airport to keep up with the busy airport's booming growth, Mark Postma, a project engineer with Carl Walker, Inc., Kalamazoo, Michigan, specified Dow Corning ® NS Parking Structure Sealant to seal expansion joints on the new 4,304 space parking structure. "Some sealants won't extend much," says Postma. "This material has high elongation properties that minimize stress on the concrete and sealant at the joint interface." Dow Corning ® brand Parking Structure Sealants are an investment in lower life-cycle costs, less downtime, maintenance savings and longer lasting parking structures. They last longer than urethane sealants because they withstand movement, UV and weather exposure, and substrate expansion and contraction without becoming brittle or losing adhesion. They are available in fast-cure, self-leveling and non-slump formulations. DOW CORNING(R) NS PARKING STRUCTURE SEALANT Product Description: Dow Corning¨ NS Parking Structure Sealant is a one-part, cold-applied, non-sagging silicone material that cures to a low-modulus silicone rubber upon exposure to atmospheric moisture. The cured silicone rubber remains flexible over the entire temperature range expected in construction applications. Properties Color Gray Durometer ASTM D2240 15 Shore A Modulus at 25% Elongation ASTM C1135 (psi) 15 psi Movement Capability ASTM C719 +100% / - 50% DOW CORNING(R) SL PARKING STRUCTURE SEALANT Product Description: Dow Corning¨ SL Parking Structure Sealant is a one-part, cold-applied, self-leveling silicone material that cures to an ultra-low modulus silicone rubber upon exposure to atmospheric moisture. The cured silicone rubber remains flexible over the entire temperature range expected in construction applications. Properties Color Dark Gray Durometer ASTM D2240 50 Shore 00 (Very Soft) Modulus at 25% Elongation ASTM C1135 (psi) 7 psi Movement Capability ASTM C719 +100% / - 50% DOW CORNING(R) FC PARKING STRUCTURE SEALANT, PART A Product Description: Dow Corning¨ FC Parking Structure Sealant is a two-part, cold-applied, self-leveling, fast-cure silicone material that cures to an ultra-low modulus silicone rubber designed for use in joints that experience thermal and/or vertical movements, especially during the early stages of sealant cure. Properties Color Medium Gray Durometer ASTM D2240 60 Shore 00 (Soft) Modulus at 25% Elongation ASTM C1135 (psi) 8 psi Movement Capability ASTM C719 +100% / - 50%   © Sealant Sales LLC • (877) 777-5300
