International Classification:
B32B 1506
US Classification:
428626, 204484, 204506
Abstract:
An electrodeposition process is provided for applying an elastomeric thermosetting, film-forming polymer to a corrosion-resistant electrically conductive substrate that is free of an electrodeposited coating. The elastomeric polymer typically is a polyurethane, a polyurea or a poly(urethane urea). The film-forming coating applied by this process provides chip resistance to the substrate. A coated article that is prepared according to the process is also provided.

PPG Industries Ohio, Inc. - Cleveland OH
International Classification:
G06F 1900
US Classification:
702 32, 356402, 356403
Abstract:
A computer implemented method for matching paint on a vehicle, having the steps of receiving in a central computer, from a remote terminal, vehicle identifying information relating to a specific vehicle and a first set of paint color data from a portion of the body of the vehicle. The central computer includes a processor, an electronic storage device in which a database is stored. The database includes vehicle identifying information for a plurality of vehicles, paint color data associated with respective vehicle identifying information, and paint formulations associated with paint color data. A first process by software in the computer determines a first best match paint formulation which relates submitted vehicle identifying information and submitted paint data to a paint formulation. The software in the computer determines a first best match paint formulation which is transmitted to the remote terminal. The central computer receives a second set of paint color data from the remote terminal representing a surface of the specific vehicle painted with the first best paint formulation and compares by a second process the second paint color data to the first paint color data so as to establish accuracy data.

Assignee:
PPG Industries Ohio, Inc. - Cleveland OH
International Classification:
C25D 1312
US Classification:
204484
Abstract:
A process for applying two electrodeposited coatings, one on top of the other, to an electrically conductive substrate is provided. An electrically conductive first coating is applied to provide for corrosion resistance and a second polyurethane-based coating is applied to the first coating to provide chip resistance. Also, aqueous dispersions of the polyurethane coating compositions are disclosed.
Cationic Electrodepositable Compositions Through The Use Of Sulfamic Acid And Derivatives Thereof

Assignee:
PPG Industries, Inc. - Pittsburgh PA
International Classification:
C25D 1306 C08L 6300 C08L 6302
US Classification:
2041817
Abstract:
A cationic electrodepositable composition containing a resinous phase dispersed in an aqueous medium is disclosed. The resinous phase has basic nitrogen groups which are at least partially neutralized with sulfamic acid or a derivative thereof, that is, an acid of the formula: ##STR1## where R is H or C. sub. 1 to C. sub. 4 alkyl. The compositions are in the form of relatively small particle size aqueous dispersions, and when used in the process of cationic electrodeposition, enable the formation of thick films with high throwpower. Also, the use of sulfamic acid passivates the anode.
Photodegradation-Resistant Electrodepositable Primer Compositions

Assignee:
PPG Industries, Inc. - Pittsburgh PA
International Classification:
B32B 2738 B05D 136
US Classification:
428416
Abstract:
An electrodepositable primer composition having improved delamination resistance with regard to automotive topcoats is disclosed. The composition is particularly useful in conjunction with topcoats which transmit ultraviolet radiation. The composition includes an ionic resin and a hindered amine light stabilizer (HALS) which is preferably a hindered aminoether light stabilizer. A preferred hindered aminoether light stabilizer is bis-(1-octyloxy-2,2,6,6-tetramethyl-4-piperidinyl)sebacate. The invention also includes a process for coating a substrate by applying the above-described primer composition and subsequently applying a topcoat. The process can alternatively include applying a standard primer composition to a substrate and subsequently applying a HALS compound to the electrodeposited substrate.

Assignee:
PPG Industries, Inc. - Pittsburgh PA
International Classification:
C25D 1306
US Classification:
2041817
Abstract:
A cationic microgel dispersion and the use of the dispersion in the method of cationic electrodeposition is disclosed. The dispersion is prepared by a process comprising dispersing in aqueous medium a mixture of a cationic polyepoxide-amine reaction product and a polyepoxide crosslinking agent and heating the mixture to a temperature sufficient to crosslink the mixture to form said cationic microgel dispersion. The dispersion can be formulated with ungelled cationic resins to form an aqueous resin dispersion which is suitable for use in the process of cationic electrodeposition providing for improved edge coverage and crater control.
