  • Publication number: 20230340354
    Abstract: An extremely rheopectic sulfonate-based grease composition and method comprising adding overbased calcium sulfonate, overbased magnesium sulfonate, and a facilitating acid, using a particular type of overbased calcium sulfonate and/or methods for adding overbased calcium sulfonate relative to the magnesium sulfonate and facilitating acid to favor the reaction between the magnesium sulfonate and facilitating acid. A preferred overbased calcium sulfonate comprises benzene rings having multiple alkyl groups. Preferred methods comprise (1) adding all calcium sulfonate after adding the magnesium sulfonate and facilitating acid, (2) adding a first portion of calcium sulfonate with the magnesium sulfonate before adding the facilitating acid and a second portion of calcium sulfonate after the facilitating acid, and/or (3) one or more calcium sulfonate delay periods relative to adding the facilitating acid.

  • Publication number: 20170266918
    Abstract: A selectively repositionable mat having a liquid-absorbing layer backed by a moisture impermeable backsheet having peripheral margins including oppositely disposed, laterally extending side margins each comprising a longitudinally extending V-fold containing a pressure-sensitive adhesive applied between two opposed surface portions of the underside of the backsheet. The V-fold can open to the outside when configured as the top part of a Z-fold disposed above the backsheet or can open to the inside when configured as a single fold disposed below the backsheet, but is desirably configured so as to permit repositionable attachment of the mat to an underlying surface or substrate for which the selectively releasable, pressure-sensitive adhesive demonstrates sufficient tackiness to hold the mat in place relative to the substrate during normal use.

  • Patent number: 8961820
    Abstract: An granular composition for absorbing liquids, the composition comprising perlite, super-absorbent polymer, a pH-indicating dye, and a minor amount of water. According to one preferred embodiment of the invention, the subject composition comprises about 80 weight percent perlite, about 5 weight percent SAP, about 0.0125 weight percent pH indicating dye (most preferably phenolphthalein), and from about 7 to about 9 weight percent water in the final product.

  • Patent number: 7670989
    Abstract: An absorbent and process for the neutralization and absorption of acidic and alkaline liquid spills comprising a mixture of superabsorbent polymer, a styrene-butadiene-styrene block copolymer, sodium bicarbonate, and optionally a chlorine neutralizer. The absorbent preferably also contains a chlorine neutralizer for the neutralization of any chlorine vapors and a pH indicator to indicate that the spill has been neutralized and is safe for handling and disposal.
