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.
