  • Publication number: 20190233761
    Abstract: A solid cleaning composition includes a solidified surfactant blend. The solidified surfactant blend includes (1) at least one metal alkyl ether sulfate having the formula: wherein the first metal is sodium, potassium, magnesium, or calcium, a is 1 or 2, AO is ethylene oxide, propylene oxide, or combinations thereof, x is 0.1 to 3, and y is 11 to 13. The solidified surfactant blend also includes a (2) solid surfactant and optionally (3) polyethylene glycol. Furthermore, (1) and (2) are present in a weight ratio of from 30:70 to 70:30 based on a total weight of the solidified surfactant blend. The solid cleaning composition has non-cohesive powder flow properties as determined using a Brookfield powder flow tester.

  • Patent number: 9649832
    Abstract: A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.
