Filler comprises polymer, metal, glass or carbon fibers or particles, magnetic particles, carbon nanotubes, carbon black, silicas, nanoparticles, nanoflakes, or its combination. The core further comprises an acid, where the acid comprises a mineral acid, a sulfonimide, an alkyl carboxylic acid, an aryl carboxylic acid, a perfluorocarboxylic acid, a halogenated phenol, a perfluoroalcohol, RSO3H, or (R'SO2)2NH.R and R'=independently selected from alkyl, alkenyl, aryl, heteroaryl, perfluoroalkyl, and perfluoroarylakyl.The acid comprises HCl, hydrogen fluoride (HF), hydrogen bromide (HBr), sulfuric acid (H2SO4), phosphoric acid (H3PO4), nitric acid (HNO3), perchloric acid, acetic acid, chloroacetic acid, cyanoacetic acid, formic acid, benzoic acid, bis(trifluoromethane)sulfonimide, nitric oxide, carbon dioxide, sulfur dioxide, chlorophenol, trifluroacetic acid, pentafluoropropionic acid, ethanesulfonic acid, toluenesulfonic acid, methane sulfonic acid, trifluoromethanesulfonic acid, fluorosulfonic acid, chlorosulfonic acid, nitrobenzenesulfonic acid, dinitrobenzenesulfonic acid, bromobenzenesulfonic acid, chlorobenzenesulfonic acid, benzenesulfonic acid, ethylbenzenesulfonic acid, 2-mesitylenesulfonic acid, p-xylene-2-sulfonic acid, naphthalenesulfonic acid or its combination. The bead further comprises a second shell enclosing the shell comprising a cyanoacrylate polymer and comprising a polymer other than cyanoacrylate. The matrix polymer is selected from thermosetting resins, thermoplastics, and elastomers. Fluid is water or an organic solvent selected from pentane, hexanes, xylene, toluene, ethyl ether, methyl t-butyl ether or its combination. The heterogenous mixture and the core comprise an acid. The base is an aqueous solution comprising hydroxide, amine, acetate, formate, benzoate, bisulfate, fluoride, monobasic phosphate, dibasic phosphate, pyridine, ammonia, or methylamine. Heterogeneous mixture comprises filler and/or one or more additives; or heterogeneous mixture comprises surfactant. Preferred Parameters: One or more cyanoacrylate monomers have a viscosity of about 1 centipoise to about 1000 centipoise. One or more cyanoacrylate monomers have set times from about 1 second to about 3 minutes. The bead has a diameter ranging from about 100 mu m to about 3000 mu m. The shell has a thickness in a range from about 1 mu m to about 150 mu m. Preferred Composition: The core comprises a mixture of about 2 to about 10 wt.% poly(methyl methacrylate), about 0.1 to about 2 wt.% hydroquinone and/or a sulfonic acid, and about 88 to about 98 wt.% of a 1-8C alkyl ester of 2-cyanoacrylate or a 2-8C alkyl ester of 2-cyanoacrylate. Preferred Process: Preparing the bead involves quenching the bead formation by adding enough acid to lower the pH to about 7 or below; and cooling the heterogeneous mixture to a temperature from about 5 degrees C to about 15 degrees C.
