Abstract
The present invention provides filled aqueous caulk and sealant compositions made from high solids aqueous binders chosen from copolymers having a mixture of backbone acid and hydroxyl groups that are copolymerized from 0.5 to 7.5 wt. %, based on total monomer weight, of an hydroxyl group containing monomer, and mixed backbone acid copolymers that are copolymerized from methacrylic acid (MAA) with a second acid monomer having a lower pKa than the pKa of MAA. Preferred, compositions comprise one or more organosilane exhibit the adhesion and joint movement capability required by ASTM C-920-08, as well as good weatherability and aged wet adhesion to glass, even at a filler to binder ratio of 0.2:1 to 4:1.
