摘要： A method for electroless coating of a substrate by applying an activating coat of polyelectrolyte or salt with a first aqueous composition, rinsing of the activating coat such that the activating coat is not entirely removed The activated surface that has remained after rinsing is then contacted with an aqueous composition in the form of a solution, emulsion or suspension to form an organic secondary coat (precipitation coat), and drying. The activating coat contains at least one cationic polyelectrolyte or at least one cationic salt in solution in water. The aqueous composition which forms the secondary coat contains constituents which can be precipitated, deposited and/or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, which is made of the activating coat and the secondary coat, has a thickness of at least 1 μm.

摘要： Autodeposition compositions for polymeric coatings of reduced gloss are prepared using resins having at least one hydroxy group and at least one epoxy group per molecule, a low temperature crosslinker and a high temperature crosslinker. The low temperature crosslinker forms a reactive prepolymer that may be subsequently mixed or emulsified with a high temperature crosslinker to form an autodeposition composition. Alternatively, a hybrid crosslinking agent may be utilized which contains both free isocyanate groups reactive at a relatively low temperature with the resin and at least one functional group capable of reacting with the resin only at a relatively elevated temperature. When deposited and cured, the resulting coating has a matte finish that is resistant to surface defects.
