摘要:
A hydrophilizing agent comprising: (a) a hydrophilic polymer which is a copolymer of N-vinylacetamide with a polymerizable monomer having a COOX group (wherein X means hydrogen, an alkali metal atom, or an ammonium salt); (b) a water-soluble urethane resin; and (c) inorganic silica. It imparts hydrophilicity and corrosion resistance to the surface of a metallic material.
摘要:
The invention relates to a mixing device for mixing a pulverulent product, which is contained in a film sachet that is soluble in liquid, with said liquid and optionally at least one additional component. The aim of the invention is to accelerate the mixing of pulverulent products, which are packed in film sachets that are soluble in liquid, with a liquid, without the risk of creating dust. This is achieved by a sealable mixing container (2) comprising a receiving chamber (7) for the pulverulent product (9) contained in the film sachet (8), the liquid and the optional additional component. The receiving chamber (7) is equipped with fitted components (6, 6′), which act mechanically on the film sachet (8).
摘要:
A granulate for particulate detergents or cleaning agents, the granulate containing a detergent or cleaning agent active ingredient and an outer encapsulation layer formed of polyvalent metal salts of an unbranched or branched, unsaturated or saturated, mono- or polyhydroxylated fatty acid having at least 12 carbon atoms or a mixture of the salts. Also, a process for making the granulate by applying to the granules an encapsulation material that comprises one or more polyvalent metal salt or salts, preferably in the form of an aqueous dispersion in a fluidized bed process.
摘要:
An adhesive composition and the use thereof to produce barrier-effect composite films. The adhesive composition contains polymer binders and fillers having a platelet-like crystallite structure with an aspect ratio of >100. The composite films produced with this adhesive exhibit barrier characteristics against the migration of oxygen, flavors and water vapor. These films are useful for packaging foods and medicaments.
摘要:
Polyurethane prepolymers containing NCO (isocyanate) groups and having a low content of monomeric polyisocyanate, processes for their production and uses employing these prepolymers. The polyurethane prepolymers of the invention are produced from by a reaction employing monomeric polyisocyanates and polyols.
摘要:
Condensation products prepared from cyclic carboxylic anhydrides of dicarboxylic acids, tricarboxylic anhydrides or tetracarboxylic anhydrides and difunctional polyamines, in particular polyoxyalkyleneamines, are suitable as a builder component for epoxy resin compositions. The reaction products based on tricarboxylic anhydrides or tetracarboxylic anhydrides are distinguished by having on average more than one imide group and carboxyl group per molecule. The compositions may optionally also contain condensation products obtained from tri- or poly-functional polyols and/or tri- or poly-functional amino-terminated polymers and cyclic carboxylic anhydrides, wherein the latter reaction products contain on average more than one carboxyl group per molecule. These compositions additionally contain conventional rubber-modified epoxy resins together with liquid and/or solid polyepoxy resins and conventional hardeners and accelerators and optionally fillers and rheology auxiliaries. Such compositions are particularly suitable as impact-resistant, impact/peel-resistant and peel-resistant adhesives in vehicle construction and in electronics. Particularly at very low temperatures, these adhesives exhibit very good impact and peel properties combined with very good corrosion resistance and ageing resistance of the adhesive bond.
摘要:
A structural member having at least two non-coplanar surfaces is reinforced by providing a drop in insert between the surfaces. The insert is a carrier having an expandable structural foam intimately bonded to the carrier. When the foam is expanded, the foam becomes intimately bonded to the surfaces of the structural member to reinforce the structural member.
