摘要:
The invention relates to a first method of bonding a first substrate to a second substrate, comprising the steps of a) applying an UV-curable adhesive resin composition comprising a photolatent base to at least one transparent surface of at least one of said first and second substrates, b) bringing said first and second substrates together with said adhesive composition there between, c) exposing said adhesive composition to actinic radiation to effect curing or alternatively to a second method of bonding a first substrate to a second substrate, comprising the steps of a) applying a UV-curable adhesive resin composition comprising a photolatent base to one surface, b) exposing said adhesive composition to actinic radiation to effect curing, c) bringing said first and second substrates together with said adhesive composition there between.
摘要:
Certain NH sterically hindered amine compounds of the formula where R is a straight or branched alkyl group of from 7 to 17 carbon atoms and where n is a numeral from 6 to 18 are suitable for use as stabilizers in lubricant compositions. The sterically hindered amines are non-aggressive towards fluoroelastomer O-rings or seals.
摘要:
The present invention is directed to a method for preparing a cellulose reactive adduct of polyvinylamide and a composition resulting from the method. The preparation of the cellulose reactive adduct is carried out close to a Critical Concentration defined herein. When the reaction is run close to this Critical Concentration, the risk of gelation is minimized, consumed glyoxal is maximized, and shelf live is enhanced. Additionally, the glyoxalated vinylamides of the present invention impart improved wet and dry strengthening efficiency to paper and paperboard when compared to adducts disclosed in previously described art.

摘要:
The present invention relates to a process for the preparation of a plane-parallel structure (a platelet-shaped body, or flake), comprising at least one dielectric layer consisting of oxides of one or more metal selected from groups 3 to 15 of the periodic table, which method comprises: (a) optionally applying a layer of release material on a substrate, (b) applying a composition comprising one or more precursors of one or more desired metal oxides to said release layer, or directly to a substrate with no layer of release material, (c) subjecting the one or more precursors of one or more desired metal oxides to microwave radiation to form a metal oxide layer on the substrate or on the layer of release material; and (d) separating the resulting metal oxide layer from the substrate as plane-parallel structures.
摘要:
A method for producing infra-red reflective substrates, including moulded polymeric articles, films, fibers and coatings and other organic and inorganic materials, by incorporating into the substrate or onto the surface of the substrate an effective amount of a tetrabenzodiazadiketoperylene colourant (pigment or dye) of Formula (I) in an amount effective to impart to the organic or inorganic substrate an infra red refelctance of greater than 50 percent at wavelengths between 800 and 1200nmH. The thus obtained, also claimed substrates so produced are transparent to much of the IR radiation not reflected and articles, such as multilayered polymeric articles, are produced which can also be subjected to laser welding.
摘要:
The invention pertains to a novel, simpler dry-milling method for comminuting crude pigments (especially crude phthalocyanines) for use in offset inks, wherein a high amount of resin is used, at least part of which is a low molecular phenol-modified rosin, an esterified rosin or a hydrocarbon resin of similar properties, preferably together with an antioxidant, and dry-milling is performed at relatively low temperature. The invention also pertains to the thus obtained, new compositions, which are extraordinarily easily dispersible in hydrocarbon solvents, and their use for the preparation of inks or ink concentrates. Pigment dispersions obtained from the preferred compositions are also claimed.
