E-Curb penetration seals replace old-style metal pitch pans with versatile, precast components and 1-Part polyether pourable sealants. CHEM LINK’s E-Curb System can usually be installed in under 15 minutes and never requires flashing or mechanical attachment. E-Curbs are designed for use on granulated modified bitumen, asphalt and coal tar B.U.R. (built up roofing). E-Curbs are specified for PVC, EPDM, PIB, and TPO single ply roofing membranes. E-Curbs are highly versatile for sealing penetrations around solar panel mounts, HVAC, Electrical, and any type of structural supports. TPO Primer is required for use with TPO single-ply roof membrane.
Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Remove all previously applied caulk, mastic, cement, asphalt, and other contaminants from penetrations with a wire brush. Brush away all gravel or loose granules. Isopropyl alcohol is an effective cleaner for surface preparation. Please contact customer service for application guidelines with temperatures below 32°F (0°C). Do not use on TPO without the use of TPO primer. Do not use on Hypalon. Smooth APP membranes require a granulated target. This product sets rapidly upon exposure to moisture. Please refer to data sheet for step-by-step installation guidelines.
