Abstract
A composition comprises thermally expanded microspheres suspended in a non-Newtonian fluid. The composition can be used for water-based applications, such as emulsion explosives, paint, water based coatings, coatings for thermal printing paper and other, porous ceramics, gypsum board, modelling clay, crack fillers, and cementitious compositions.
Claims16
A composition comprising thermally expanded microspheres suspended in a non-Newtonian fluid, wherein the composition has a solids content of about 0.5-20 wt.%, relative to the total weight of the composition.
A composition comprising:
- thermally expanded microspheres comprising a polymeric shell encapsulating a hollow core, wherein the hollow core comprises a blowing agent;
- and
- a biocide;
- wherein the thermally expanded microspheres are suspended in a non-Newtonian fluid;
- wherein the composition has a solids content of about 1-10 wt.%, relative to the total weight of the composition;
- wherein the non-Newtonian fluid is a liquid comprising a diutan gum present in an amount of about 0.01-10 wt.% relative to the total weight of the liquid;
- and
- wherein the polymeric shell comprises of one or more thermoplastic polymers selected from polymers obtained by polymerizing one or more vinyl monomers, lignins, polysaccharides, polysaccharide derivatives, polyesters, polyethers, polyacids, polyols, polyalkenes, polyanhydrides, or any combination thereof.
