  • Process for cleaning and disinfecting devices in the brewing industry
    Patent number: 5645648
    Abstract: A method for cleaning and disinfecting articles in the brewing industry by applying to or at the contaminated place a composition containing2 to 50% by weight of at least one compound having a peroxide group and/or a halocarboxylic acid;1 to 25% by weight of at least one amine oxide derivative stable to oxidizing agents as surfactant foam booster component andremainder up to 100% water,the figures referring to total weight of the composition, and having a pH<7.
    Type: Grant

  • Storage-stable aqueous alkali metal silicate/filler adhesive compositions and their use
    Patent number: 4403059
    Abstract: An adhesive composition based upon an aqueous solution of alkali metal silicate with a content of powdered inorganic filler, having good storage stability, which comprises an aqueous alkali metal silicate solution containing:(a) from 10% to 40% by weight of at least one powdered inorganic filler,(b) a suspension effective amount of at least one zinc soap of a fatty acid having from 12 to 22 carbon atoms and(c) from 0 to about 24% by weight of a 50% by weight stable, aqueous dispersion of an alkali-resistant organic polymer, based on the weight of the total composition.Preferably zinc stearate in amounts of from 1% to 5% by weight are added to the adhesives containing powdered inorganic fillers and optionally organic additives on a base of aqueous water glass solutions, to prevent separation phenomena. Sodium and/or potassium silicate solutions can be used, the sodium silicate solution being preferably present in the ratio by weight of 3.3 to 3.9:1 for SiO.sub.2 /Na.sub.

  • Adhesives and coating materials based upon alkali metal silicate solutions
    Patent number: 4361659
    Abstract: This invention relates to an adhesive composition based upon an aqueous solution of alkali metal silicate with a content of powdered inorganic filler and optionally organic polymer, which comprises an aqueous alkali metal silicate solution containing:(a) from about 25 to 50 percent by weight of dispersed crystalline calcium carbonate;(b) from about 2 to 10 percent by weight of quartz powder with a particle size of up to about 15 .mu.m and a specific surface area of at least about 3.5 m.sup.2 /gm; and(c) from 0 to about 24 percent by weight of a 50 percent by weight stable, aqueous dispersion of an alkali-resistant organic polymer based upon acrylate, styrene/acrylate, styrene/butadiene, or a mixture thereofbased on the weight of the total composition.
