摘要:
The present invention relates to the use of aqueous UV-reactive primers for the coating of substrates based on ethylene vinyl acetate copolymers (EVA copolymers) or rubber. The present invention further provides a novel method for joining articles using an aqueous UV-reactive primer.
摘要:
The present invention relates to novel waterborne adhesives which are polymerizable by UV light and are capable of being activated by heat, and which particularly display good adhesion to difficult substrates, such as ethylene vinyl acetate copolymers (EVA) with a low vinyl acetate content, or rubber. The invention further provides a novel method in which, after the application of the waterborne adhesive to an article and drying, irradiation with UV light and at the same time or thereafter activation by heat are performed. The adhesive film which is irradiated and activated in this way is then bonded to a further article. The invention also provides the use of the adhesives to make items such as shoes.

摘要:
The method in accordance with the invention is characterized by the steps of before an ion implantation, a dielectric diffusing layer array is formed on a substrate that has at least one oxide layer and is thick enough for the maximum of implanted ions to be inside the layer array; and post-diffusion is implemented such that no further oxidation of the substrate is possible. By these measures, it is achieved that within the semiconductor substrate the doping continually decreases towards the pn-junction, apart from a very narrow segregation area, the result being an electrical field that conducts substantially all charge carriers generated in the area between the surface of the substrate and the pn-junction to this pn-junction. This achieves a quantum efficiency in the short-wave range that is considerably greater than that achievable with conventional photodetectors.
摘要:
A method for reinforcing a part of a building comprises the step of adhesively bonding a textile to the surface of the part of a building by means of an adhesive. The invention relates further to such a reinforced part of a building and to the use of a textile in combination with an adhesive for reinforcing a part of a building, wherein the textile is adhesively bonded to the surface of the part of a building by means of an adhesive.

The present invention relates to aqueous compositions based on crystalline or semicrystalline polyurethane polymers, processes for the preparation thereof and adhesive systems comprising these aqueous compositions and the use thereof.
摘要:
The invention relates to adhesives based on aqueous dispersions and surface-deactivated isocyanate particles and to latently reactive coatings, films and powders produced from such dispersions. The adhesives are prepared from aqueous compositions containing a) dispersed polymers with isocyanate-reactive groups; b) at least one dispersed surface-deactivated aliphatic solid polyisocyanate with a softening temperature of ≧40° C.; c) one or more compounds of elements from subgroups 5 and 6 of the periodic system of elements, in which the particular element has an oxidation number of at least +4 and, d) optionally further additives and auxiliaries.
摘要:
The invention relates to aqueous dispersion adhesives based on a mixture of aqueous polyurethane or polyurethane-urea dispersions, to a process for their preparation, and to the use of the dispersion adhesives in the production of adhesive composites.
摘要:
A device and a method with a memory for the storage of data with a means for limiting the access rights to the data for a user. Usernames provided at authentication posse specific user rights, such as super administrator rights or independent inheritance rights. Thus the rights management is simplified to a certain degree, since the administrator is not required to assign rights to additional users. Furthermore, a temporal process of rights control is provided, whereby the administrator is not required to controlling the granting or terminating rights.
摘要:
An isolate of useful bacteria, preferably of the genus Pseudomonas, preferably of the species Proradix, is used for the treatment of plants and/or seed and incubated in a culture medium containing phosphorus compounds, nitrogen compounds and succinic acid. The solution can be used directly for spraying plants and/or seed, optionally followed by vacuum treatment. Furthermore, the solution can be vacuum-dried, the powder being dissolved in water prior to use.
