Abstract: Sealant is applied onto or into a folded-seam closure of a metal can. Instead of introducing sealant into the U-shaped lid flange and drying, the compound or sealant is applied to the flange base. The base of the metal can is dipped into a current of fluid sealant or at least brought into contact with it at the surface. This substantially improves the precision of dosing and the exact amount of applied sealant.

Abstract: An invention is described through which it is possible to reduce in quantity the coloured, mostly dark, and frequently adhesive deposits which form in lead accumulators with separators of filled poly-olefins during formation and operation. The essential feature is that the separators contain as plasticizer a process oil with a CA value of ≦6%, a sulphur content of ≦2000 ppm and a polar part of ≦1%. Preferred process oils to be used as plasticizers are relatively naphthenic and naphthenic oils.

Abstract: A hardenable polyester molding material contains a mixture ofI. an ethylenically unsaturated ester or a terminally unsaturated vinyl ester,II. copolymerizable monomers,III. 6-25% by weight, based on I+II, or a graft polymer P, in which there are grafted onA. 5-95% by weight of an elastomeric polymer,B. 95-5% by weight of a polyadduct, polycondensate or acrylic polymer which contains olefinic double bonds, with or withoutC. 0-90% by weight of vinyl monomers, andIV. 5-300% by weight, based on I+II, of fibrous reinforcing agents.

Abstract: For the production of printing plates, in particular lithographic printing plates by exposing a photopolymerizable recording material imagewise to actinic light and then effecting development with an aqueous alkaline developer, it is proposed to use photopolymerizable recording materials possessing a photopolymerizable copying layer (L) applied on a dimensionally stable base, where, in addition to containing ethylenically unsaturated photopolymerizable low molecular weight compounds, one or more photoinitiators, dyes and/or pigments, and, if required, further additives and/or assistants, the said copying layer (L) also contains, as a binder, one or more oligomeric and/or relatively high molecular weight copolymers which are soluble or dispersible in aqueous alkaline media and are based on cyclic dienes, in particular unsubstituted or substituted cyclopentadiene or unsubstituted or substituted di- or tricyclopentadiene.

Abstract: Mixtures which are liquid at room temperature, have a long shelf life and can be activated by heat and which comprise(A) polyols and/or polyamines, component (A) having a viscosity of less than 100 Pa.s at room temperature, the OH number being less than 112 and the mean functionality of the starting materials being from 1.1 to 6, and(B) polyisocyanates which are dispersed in (A), are stabilized to (A) as a result of a phase-separating deactivation at the surface of the dispersed particles, and are present in an amount such that there are from 0.1 to 2 equivalents of the total isocyanate present in the polyisocyanate per equivalent of hydroxyl or amino groups of component (A),are particularly useful for contact adhesives.
