Abstract
A foamable sealant composition having a density, when foamed, of from 0.4 to 1.8 g/cc, and containing a latex binder, foam-generating composition, foam stabilizer, rheology modifier and water, is provided. Also provided is a method of sealing a vehicle using the foamable sealant composition.
Claims12
A foamable composition comprising:
- (a) a latex binder composition comprising, as polymerized units at least one acrylic or methacrylic monomer,
- wherein said binder has a Tg from −35 to 35° C.;
- (b) a foam-generating composition selected from the group consisting of a profoamant surfactant comprising an anionic or nonionic surfactant having a hydrophilic-lipophilic balance of from 8 to 20, and a blowing agent;
- (c) a foam stabilizer;
- (d) a rheology modifier;
- (e) water;
- wherein the composition, when foamed has a density of from 0.4 to 1.8 g/cc.
