UCAR Latex 169S UCAR™ Latex 169S was developed as a binder for high-performance clear and pigmented sealants. It combines exceptional stress-strain properties with a low Tg matrix to provide the elasticity required to meet the performance standards of ASTM C 920 when properly formulated. The high latex solids provide wide formulation latitude and low sealant shrinkage, which can reduce the cracking tendency of paint applied over fresh sealant. The latex has inherently good pigment binding capacity that allows formulation of ASTM C 834 compliant sealants with pigment-to-binder weight ratios of 5 to 1.
