DuraLink 50 is an extremely elastic, moisture cure, elastomeric sealant designed for use in roofing, cementitious siding, metal architecture, curtain wall construction and joints subject to movement. DuraLink 50 has excellent elastomeric properties which is ideal for a wide range of applications including difficult surfaces such as Kynar 500® PVDF, other anodized metals and coatings, and can be used as a vinyl siding sealant as well. DuraLink 50 is isocyanate free, paintable and SWRI validated for ± 50% joint movement.
Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Isopropyl alcohol is an effective cleaner for surface preparation. Install all joint applications per ASTM and SWRI recommendations and guidelines. Please contact customer service for application guidelines for temperatures below 32 degrees F (0 degrees C). Maintain sealant at room temperature before application to ensure adequate tooling and adhesion. This product sets rapidly upon exposure to moisture.
