  • This book describes more than 1500 currently available prepaint specialties and surface tolerant coatings. It has been compiled from information received from 67 manufacturers and distributors of these products. Specialty prepaint products and surface tolerant coatings make up a small, but growing segment of the paint and coatings industry. These products are particu- larly attractive to the do-it-yourself market and to small contractors. They also find use in the marine and transportation industries, and in the refinishing market. ...

  • Hexabromobenzene (HBB) has been used as a flame retardant in polymers, plastics, textiles, wood and paper. Its primary uses have been reported in the plastics, paper and electrical industries (Bruchajzer et al., 2004). U.S. production/import volume was listed as 10,000- 500,000 pounds for 1998, but no information is available beyond that time (U.S. EPA, 2002). In addition to its use as a flame retardant, HBB is a thermal decomposition product of octa- and decaBDEs and hexabromobiphenyl (as cited in Bruchajzer et al., 2004).

  • In modifying soil pH, the addition of amendments, fertilizers, tillage practices, soil organic matter levels, and drainage should all be considered. A common amendment used to acidify alkaline soils is sulfur (S) (Slaton et al., 2001). Elemental sulfur (S0 ) is oxidized by microbes to produce sulfate (SO4 2- ) and H+, causing a lower pH. Ferrous sulfate (FeSO4 ) and aluminum sulfate (Al 2 (SO4 )3 ) can also be used to lower pH, not due to SO4 , but because of the addition of acidic cations (Fe2+, Al 3+) (see Q & A #1).

  • In 1993, the U.S. Department of Energy (DOE) Office of Industrial Technology (OIT) established a group of seven industries designated as Industries of the Future (IOF). These industries were selected for their high energy use and large waste generation. The original IOF included the aluminum, chemicals, forest products, glass, metalcasting, petroleum refining, and steel industries. Each industry was asked to provide a future vision and a road map detailing the research required to realize its vision.

  • The appropriate conditions have been found for syntheses of a series of azomethines using the reaction between cyclohexylamine and different aromatic aldehydes. The structures of products have been determined by the data of IR- and 1 H-NMR-spectra. All obtained azomethines have metallic inhibition corrosion capacities on CT-3 steel and aluminum in different levels. The influences of structures to their metallic inhibition corrosion capacities have been discussed.

  • A series of seven azomethines has been synthesized from p-nitrobenzaldehyde and different substituted anilines. The structures of products have been determined by the data of IR-spectra. All obtained azomethines have metallic inhibition corrosion capacities on CT-3 steel and aluminum in different levels: the protection effects were 41-57% on CT-3 steel and 83-92% on aluminum. The influences of structures to their metallic inhibition corrosion capacities have been discussed.
