摘要:
The invention relates to a biostatic neutralizing composition for aqueous fluids, including two amines, one of which is dihydroxyethylamine. The invention also relates to the use of such a composition as a biostatic neutralizing additive for industrial aqueous fluids. The invention further relates to the industrial aqueous fluids containing such a composition.
摘要:
The present invention concerns the field of fluorinated hydrocarbons and relates to novel compositions containing fluorinated hydrocarbons and oxygenated solvents. More particularly, the compositions comprise a fluorinated base, diacetone alcohol (DAA), and DMSO and/or secondary butanol. These novel compositions can be used in particular in all solvent applications of HCFC 141b (hydrochlorofluorocarbon 141b), in particular in various operations for treating solid surfaces, such as the cleaning, degreasing, defluxing or drying of solid surfaces.
摘要:
The present invention is related to a stripping composition for paints, varnishes or lacquers. This composition contains at least water and anisole.
摘要:
This composition for stripping paints coating a substrate, in particular for stripping paints and primers with a high degree of crosslinking, in particular of the epoxy, polyurethane and alkyd type, is characterized in that it consists of or comprises: (A) 50 to 80 parts by weight of water; (B) 20 to 50 parts by weight of benzaldehyde and/or of benzyl alcohol; (C) 5 to 15 parts by weight of at least one activator chosen from formic acid, formic acid totally or partially neutralized with a base, and bases; and (D) 0.5 to 10 parts by weight of at least one thickener, the said thickener necessarily being a thickener of acrylic nature when (B) consists solely of benzyl alcohol, (A)+(B) representing 100 parts by weight.
摘要:
The present invention concerns the field of fluorinated hydrocarbons and relates to novel compositions containing fluorinated hydrocarbons, secondary butanol and optionally DMSO. These novel compositions are particularly advantageous for defluxing electronic boards in particular for defluxing electronic boards containing “no clean” solder fluxes.
摘要:
The present invention relates to a liquid composition for the cold preparation of laminate composite materials so as to confer to them, without preliminary sanding or abrasion, a surface state favorable to adhesive bonding with polyurethane type adhesives comprising (a) at least one polar aprotic solvent (TPA); (b) at least one ether (TE) selected from ethers, ether-esters, and ether-ketones having: a molar volume less than 200 cm3/mole and preferably less than 160 cm3/mole, a molecule devoid of a hydroxyl function, and (c) at least one activator (TA) comprising at least one reactive nitrogenous function of the —NH2 and/or —NH— type of molar volume less than 100 cm3/mole.
摘要:
The invention relates to a stripping composition which can be used in the construction field, especially for the stripping of external organic coatings, such as exterior waterproof coatings and thin films, and in the yachting field, for the stripping of antifouling coatings, characterized in that it comprises: at least one dibasic ester, at least one dipolar aprotic solvent, at least one inorganic filler, water, at least one cellulose thickener, at least one dispersing agent and activators.
