UCAR Latex 163S UCAR™ Latex 163S is a high solids, all-acrylic binder for high-performance caulks, sealants, and elastomeric coatings. UCAR Latex 163S combines extraordinary adhesion properties, high pigment binding capacity, and excellent exterior durability. This unique combination of performance properties allows the formulator to prepare ASTM C 920 compliant, class A and B sealants. Due to the inherently high pigment binding capacity of UCAR Latex 163S, ASTM C 834 compliant formulations are now available with pigment-to-binder ratios as high as 5:1. Even higher pigment loading levels are being utilized in non-specification painters caulks.
