Astm C 920 Sealant -

This indicates the percentage of movement (expansion and compression) a sealant can handle relative to its original joint width. Movement Capability Common Applications Low-movement interior trim or molding. 25 Standard window perimeters and expansion joints. 35 High-performance joints, such as pre-cast concrete panels. 50 High-movement curtain walls and glazing systems. 100/50 +100% / -50% Extreme asymmetric movement (expansion up to 100%). 4. Use: Application Environment and Substrates

These involve two or more parts that must be mixed before application. They typically offer faster curing times and are often used for high-volume or specialty applications. 2. Grade: Flow Characteristics astm c 920 sealant
