A high solids, high-performance acrylic latex binder designed for pigmented caulks and sealants. Due to the self-thickening nature of this binder, this product has a lower thickener demand than other sealant binders. With its high pigment binding capacity, this product can be successfully formulated into a broad range of products – from economical non-specification caulks to high-performance sealants meeting ASTM C920, Class 25. Sealants formulated with this product exhibit excellent durability and exceptional adhesion. "RHOPLEX™ A-920 emulsion polymer contains up to about 36% bio-based carbon content* sourced from plants, replacing material sourced from petroleum. This offers a more sustainable option by reducing the product carbon footprint in caulk and sealant applications. *BCC – % Biobased Carbon Content ASTM D6866-21 Method B (AMS), tested by independent laboratories specialized in C14 testing. Ratios may be subject to availability of sourced bio-based materials."
