Stable foam caulk, sealant and insulation compositions are disclosed. The compositions comprise solid, waxy non-ionic lipophilic surfactants having low HLB values. These surfactants, upon foamed dispensing of the composition, provide stable support for bubbles formed from drying of a latex emulsion of a film forming polymer and a volatile liquid hydrocarbon propellant. In addition to use in caulking, sealant or insulation methods, the composition can be used to form artificial terrains and other hardenable structural surfaces as backgrounds or support means for hobbies, crafts, and the like.

Stable, foamed caulk and sealant compounds and methods of use thereof

Stable foam caulk, sealant and insulation compositions are disclosed. The compositions comprise a waxy, solid foam stabilizer and a liquid lithophilic surfactant having low HLB value of about 3-14. The foam stabilizer provides stable support for bubbles formed from the drying of the latex emulsion of film forming polymer, and the volatile liquid hydrocarbon propellant. In addition to the use in caulking sealant or insulation methods, the compositions can be used to form artificial terrains or other hardenable structural surfaces as backgrounds or support means for hobbies, crafts and the like.
