Abstract
A spray latex foam for filling wall cavities to enhance the sealing and insulating properties of a building is provided. The spray latex foam includes a latex system and a gaseous coagulating component. In at least one exemplary embodiment, carbon dioxide is included as a gaseous coagulating agent. One latex suitable for use in the spray foam is polyvinylidene chloride (PVDC), which possesses fire retardancy and environmental durability. However, a preferred latex is styrene-butadiene rubber (SBR). The latex system may also include a thixotropic agent, such as Laponite® RD synthetic clay. The spray latex foam is polyurethane-free. A method of preparing a spray latex foam that includes supplying a latex system and adding a gaseous coagulating component to the latex system is also provided.
