Sto Corp., the innovative North American leader in exterior claddings, air barriers, coatings, and building restoration solutions, has launched StoSeal™ STPE Sealant, a premium, low-odor, isocyanate free, one-part hybrid sealant with a VOC content of 8 g/L. StoSeal STPE Sealant is durable, flexible, resistant to moisture and weathering, and tested to perform per ASTM C920 class providing Type S, Grade NS, Use NT, A, M, and +100/-50% movement capability. It meets Federal Specification TT-S-00230C Type II and AAMA 808.3 (Type 1) Exterior Perimeter Sealing requirements and has been tested in accordance with ASTM C1382 for use with EIFS systems.
“StoSeal STPE Sealant’s excellent adhesive properties provide primer-free bonding to most substrates and fast tack-free and cure times, resulting in a paintable, low dirt pickup sealant for new opaque wall and building restoration applications,” says Director of Business Development Richard Martens. “It works effectively with StoTherm® ci, StoPowerwall®, StoQuik®, StoVentec® exterior wall systems and with StoGuard® air and water-resistive barrier systems. It is suitable in panel-to-panel joints in prefabricated construction, metallic and cementitious substrates, storefront systems, interiors, concrete repair, and air sealing applications.”
