Pecora Dynaflex SC 20oz Sausage - Limestone
Pecora Dynaflex SC is a one-part, non-sag, tamper-resistant elastomeric STPU (silyl-terminated polyurethane) joint sealant. It is used on expansion and control joints and other masonry or metal openings in institutional, correctional, and public buildings where ordinary sealants are easily damaged. It is placed as a Limestone 20oz sausage when leftover masonry-toned security joints need a tamper-resistant bead on long sausage runs. The surface is tack-free in about 90 minutes, and a 1/4 inch section cures through in 48 hours.
