Disclosed are sulfur-containing molybdenum complexes used in compositions and methods for inhibiting or reducing the deposition of foulant on equipment.

Disclosed herein are methods for reducing fouling caused by process water present within a water recycling loop of a pyrolysis plant. Fouling is caused by phase separation and accumulation of materials from the process water on equipment surfaces. The method includes applying a total of about 5 ppm to 500 ppm total of a first polymerization inhibitor and second polymerization inhibitor to the process water to form a treated process water, wherein the first polymerization inhibitor has a pygas-water partition coefficient of about 0.0001 to 9 and the second polymerization inhibitor has a pygas-water partition coefficient of about 1000 to 50,000.

A mixture for coating a metal substrate to prevent or limit scale formation. The mixture comprises 20 to 90% by weight of at least one of: an oxide ceramic material, an aluminosilicate mineral or glass frit. The mixture further comprises 1 to 20% by weight of clay and 3 to 70% by weight of an alkali metal silicate.

Provided is a pressure-sensitive adhesive (PSA) sheet including a PSA layer formed from a PSA composition including a base polymer, crosslinking agents of two or more species having mutually different types of crosslinkable functional groups, and an azole-based rust inhibitor. Here, one of the crosslinking agents of two or more species is an isocyanate-based crosslinking agent. Monomeric components constituting the base polymer include a carboxy group-containing monomer. The amount of the azole-based rust inhibitor in the PSA layer is less than 8 parts by weight with respect to 100 parts by weight of the base polymer.

Provided is a pressure-sensitive adhesive (PSA) sheet having a low relative dielectric constant, satisfactory metal corrosion preventing property, and excellent member holding performance. The present invention provides a PSA sheet having a PSA layer including a base polymer and a rust inhibitor. The base polymer is an acrylic polymer, and monomeric components constituting the acrylic polymer comprise a (meth)acrylate having an alkyl group having 5 or more carbon atoms at an ester end at 50% by weight or more of the monomeric components. The PSA layer has a relative dielectric constant of 3 or less at 300 kHz.

A rust particle remover, comprising a core (1) and an outer sleeve (2). The core (1) is made up of a magnet comprising a magnetic field strength of at least 13.2 Tesla and is introduced into the outer sleeve (2) by means of pressure pressing. The patent application is based on the problem of preventing signs of rust on cutlery and metal parts caused by rust particles, which are transported by tap water.
