Latest Patents

John E Swalwell holds a patent for "Stable aqueous film-forming dispersions." This invention focuses on the preparation of stable aqueous dispersions of particles of film-forming polymer. The particles consist of at least one pre-formed polymer and at least one polymer formed in situ, referred to as multi-polymer particles. The invention overcomes the inadequate stability exhibited by many previously known systems, especially in the presence of co-solvents. By preparing the particles in the presence of a stabilizing compound, which is an amphipathic compound with a hydrophilic-lipophilic balance (HLB) value of at least 8, the stability of these dispersions is enhanced. The dispersions developed through this invention are particularly useful as film-forming components in coating compositions.
