Clear - High-Performance, Moisture-Curing Polyether Sealant

Product Description: Clear is a moisture-curing, polyether sealant designed for application in damp, dry, or cold climates. It is solvent-free and contains no isocyanates. Clear will not shrink upon curing, will not discolor when exposed to UV light, and will not "out-gas" or bubble on damp surfaces as urethane sealants often do. It has resilient elastomeric properties and excellent adhesion to most construction materials, capable of joint movement in excess of 25% in both compression and extension. Clear can be used effectively in many challenging construction site conditions, curing in wet or dry climates and at low temperatures (32°F, 0°C).
