Abstract:
The present disclosure provides a formula of a remover reagent for a cured silicone sealant and a method using the same. The remover reagent is prepared from an acid catalyst and a solvent each having a high boiling point and a high flash point. The acid catalyst is benzenesulfonic acid or alkylbenzenesulfonic acid. The solvent is mineral oil and/or silicone oil. The cured silicone sealant is first soaked with the remover reagent for 30 to 120 min, and then baked at a high temperature of 80 to 120° C. for 10 min or above into debris or powder, whereby the cured silicone sealant with a thickness of 10 mm or above can be removed. Moreover, the remover reagent has the advantages of readily available raw materials, high safety, environmentally friendliness, convenient preparation and good sealant removal effect, and thus, has good application prospects.
Abstract:
The present invention generally relates to methods for removing an organic deposit or for inhibiting deposition of deposit-forming comprising contacting a cleaning composition or an anti-coking composition with a surface. The surface can have an organic deposit or be susceptible to forming an organic deposit and the surface can be in contact with a liquid containing organics. The liquid can be produced from a thermal recovery system, and the surface can be an internal surface of a piece of steam-generating or vapor-generating equipment.
Abstract:
The disclosed invention relates to a two-part liquid composition for cleaning and disinfecting a substrate, comprising: (A) a disinfectant medium comprising peracetic acid; and (B) a supplemental medium comprising a non-enzymatic cleaner, a corrosion inhibitor, and a chelator. The supplemental medium (B) may further comprise an enzymatic cleaner, a surfactant, a buffer, a pH modifier, or a mixture of two or more thereof. The substrate may be a medical device, for example, an endoscope.

Abstract:
A cleaning composition is provided. The cleaning composition includes at least one polyamino-polycarboxylic acid or at least one salt thereof, at least one solvent, at least one substituted or non-substituted phenethylamine and water. The solvent is selected from a group consisting of glycols.
Abstract:
Embodiments of the present disclosure include cleaning processes, closed loop cleaning machines, and methods of cleaning an article. The cleaning process includes contacting a surface of an article with a cleaning composition in a cleaning chamber, where the cleaning composition includes at least about 85 percent by weight organic solvents, based on total weight of the cleaning composition, and where at least about 5 percent by weight of the organic solvents is propylene glycol, based on total weight of the organic solvents, to clean the surface of the article, collecting the cleaning composition including contaminants, and recovering the cleaning composition via distillation, where a distillation apparatus removes the contaminants from the cleaning composition and is connected to the cleaning chamber by a process stream.
Abstract:
A liquid removal composition and process for removing sacrificial anti-reflective coating (SARC) material from a substrate having same thereon. The liquid removal composition includes at least one fluoride-containing compound, at least one organic solvent, optionally water, and optionally at least one chelating agent. The composition achieves at least partial removal of SARC material in the manufacture of integrated circuitry with minimal etching of metal species on the substrate, such as aluminum, copper and cobalt alloys, and without damage to low-k dielectric materials employed in the semiconductor architecture.
Abstract:
A solvent or composition that includes a glycerin short-chain aliphatic ether may be used in a method for coupling, coalescing or adjusting viscosity of a composition.
