Product Description
NovaLink TX is a versatile, moisture-curing sealant for damp, dry, or cold climates. This polyether elastomeric sealant is solvent-free, contains no isocyanates, and will not shrink or discolor upon curing. It offers excellent adhesion to most construction materials and accommodates joint movement in excess of 35%. NovaLink TX can be applied in wet or dry conditions and at temperatures as low as 32°F (0°C), making it ideal for challenging construction environments.
