Water-based acrylics can be painted, can be cleaned with water, and require less surface preparation than solvent- and silicone-based caulks and sealants. Water-based acrylic caulks and sealants have less of an odor than solvent- and silicone-based products. Solvent- and silicone-based caulks and sealants are generally more flexible than acrylics and can withstand more sunlight and temperature extremes. They require solvents to clean, are more difficult to remove than acrylics, and generally cannot be painted. Water-based acrylic caulks and sealants with added silicone offer a variety of features, depending on the specific formula. Momentive manufactures s and materials such as ceramics, resins, silicone, adhesives, and sealants. The company is headquartered in Columbus, OH.
