20090149588 | PLASTIC PIPE MADE OF POLYOLEFIN - A plastic pipe is made of a cross-linked polyolefin to be utilized in, but not limited to, potable water applications. Certain antioxidants and stabilizers are added to a process for producing the plastic pipe. The added antioxidants and stabilizers remain as key components in the final plastic pipes, providing superior long term stability and resistance to oxidative degradation, the latter being caused by but not limited to, chlorinated water environments. At least a primary stabilizer is used in the material. | 06-11-2009 |

20100137494 | SHEAR-INDUCED ALIGNMENT OF NANOPARTICLES IN COATINGS - Methods and apparatuses for forming linear nanoparticle arrays, and the nanoparticle formulations formed therewith, are described. The nanoparticle arrays may be incorporated into coating materials, and in one example may be provided at or near the surface of two-component polyurethane coatings for use in automotive refinish clear coats. Coatings incorporating such nanoparticles may be applied to a substrate under shear to cause the nanoparticles to arrange linearly. | 06-03-2010 |

20100084037 | METHODS AND COMPOSITIONS FOR COATING PIPE - Compositions and methods for producing multi-layered plastic pipes are described. Some embodiments of the compositions comprise a cross-linkable polymer system (for example, based on either acrylate or epoxy chemistry), a photoinitiator, and one or more additives such as a pigment, an antioxidant, a light stabilizer, or other additive. In an exemplary method of producing a multi-layered plastic pipe, a base pipe, for example comprising cross-linked polyethylene, is conveyed through an oxidizing step in which at least the outer surface of the base pipe is oxidized, through a coating step in which a pre-polymer system is applied to the outer surface of the base pipe and through a curing step in which the pre-polymer is cured to form a layer of the pipe. | 04-08-2010 |
