Chem Link NovaLink® 35 F1253AG 20 oz Aluminum Joint Sealant 12 per Case. NovaLink 35 is a moisture curing, polyether, elastomeric joint sealant designed for application in damp, dry or cold climates. NovaLink 35 is solvent free and contains no isocyanates. NovaLink 35 will not shrink upon curing, will not discolor when exposed to UV light and can not “outgas” or bubble on damp surfaces as urethane sealants often do. NovaLink 35 has excellent adhesion to most construction materials and resilient elastomeric properties. NovaLink 35 is capable of joint movement in excess of 35% compression and extension. Because it cures in wet or dry climate conditions and at low temperatures 32 deg F (0 deg C), NovaLink 35 can be used effectively in many difficult construction site conditions.
