An electrically conductive black silicone paint having spacecraft applications com-
prising a mixture of IO0 parts by weight of a silicone-based polymer, and 1.35 to 3.5 parts by weight of an electrically conduc-
tive carbon pigment having a porous, spon- gelike structure and having a specific sur-
face area of at least 500 m’/g.
Coating for Molded Plastic Compositions U.S. Patent 5665,434. Sept. 9, 1997 M. Mass et al., assignors to Herbeds GmbH, Wuppertal, Germany
A method of coating plastic components
including forming a molded plastic sub- strate; applying an aqueous coating com-
position to the substrate; such coating be- ing based on polyols with ammonium
groups and polyisocyanates, and which may contain pigments and/or extenders, customary lacquer additives and one or
more organic solvents, characterized in that it contains as binder at least one (meth- )acrylic copolymer and as crosslinking
agent at least one polyisocyanate. which may be blocked.
Device for Hot-Dip Coating U.S. Patent 5665,437. Sept. 9, 1997 K. Frommann et al., assignors to Mannesmann AG, DDsseldorf, Germany
A process for coating a strip material surface with a metal coating comprising conducting the strip material upwardly in a
vertical direction through a bath of molten coating malerial.
Photoresist Stripping Composition U.S. Patent 5,665,688. Sept. 9, 1997 K. Honda et al., assignors to Olin Microelectronics Chemicals Inc., Norwalk, Conn
A photoresist stripper composition corn- prising 20 to 70% by weight of a cyclic
amide organic polar solvent having a di- pole moment of more than 3.5; 70 to 20% of an alkanolamine compound; and 0.1 to 10% by weight of 6.6’,6”-( l,.QStriazine-

Galvanized Open or Closed Steel Sections U.S. Pafent 5,666,714. Sept. 16. 1997 TM. Hejghf et al. assignors to Tubemakers of Australia Ltd., Sydney, Australia
A method of manufacturing galvanized open or closed steel sections comprising a
roll forming process followed by a hot-dip galvanizing process, the roll forming pro- cess comprising removing scale on both
sides of a substantially flat steel strip by way of in-line shot blasting prior to form- ing the strip into an open section or hollow
welded section, after the roll forming pro- cess. immersing the formed section in a
flux solution. and the hot-dip galvanizing process not including a pickling or subse- quent rinsing step.
Attention: Chrome Platers and Anodizers - Lo-Mist reduces emissions below new EPA and OSHA limits:
You are currently facing strict new guidelines on chro- mium emissions and employee exposure. Just small additions of Lo-Mist will provide immediate compliance for decorative platers and anodizers, and greatly reduce equip- ment and maintenance requirements for hard chrome platers.
Here’s how Lo-Mistwill benefit you: l Dramatic reduction in surface tension provides
worker safety and environmental protection; l Highly concentrated liquid for best results at low
cost; l Permanent-type surfactant maintains compliance
without build-up of trivalent chrome; l No pitting even with heavy plate (10 mil); l No foam build-up eliminates need for additional
cooling. For additional information about Lo-MM, call
