The present disclosure relates to insulation. Teachings thereof may be embodied in a solid insulation material, especially in tape form, the use thereof in a vacuum impregnation process and to an insulation system produced therewith, and also an electrical machine comprising the insulation system, especially for the medium- and high-voltage sector, namely for medium- and high-voltage machines, especially rotating electrical machines in the medium- and high-voltage sector, and to semifinished products for electrical switchgear. For example a solid insulation material with an anhydride-free impregnating agent may include: a carrier; a barrier material; a curing catalyst; and a tape adhesive. The curing catalyst and the tape adhesive are inert toward one another but react under the conditions of a vacuum impregnation process if combined with an anhydride-free impregnating agent having gelation times of 1 h to 15 h at impregnation temperature. The tape adhesive is free of oxirane groups and includes at least two free hydroxyl groups.

A plastics material component for an aircraft includes (i) a substrate, which comprises one or more thermosetting plastics materials, and (ii) one or more layers which are applied to the substrate, at least one layer S1 comprising mica. A method for producing the plastics material component includes providing a substrate including at least one thermosetting plastics material or one polymer which is crosslinked to form a thermosetting plastics material, and applying one or more layers to the substrate, wherein at least one layer includes mica. The mica-containing layer is applied directly to the substrate and the application is carried out before and/or during the curing of the thermosetting plastics material.

A gas barrier film according to the present invention includes: a resin film substrate; a first layer made of an aqueous coating agent (C) that contains a water soluble polymer (A) and an inorganic layered mineral (B); and a second layer made of a coating agent (D) that contains titanium oxide, the first layer and the second layer being disposed in this order on at least one surface of the resin film substrate.

A self supporting board for use in fire protection, at least part of the board being formed from material comprising in wt %: inorganic fibres 35 to 70% silica 30 to 65% 5 binder 0 to 10%.

Water-based adhesive compositions are improved by the incorporation of hollow polymeric microspheres having outer surfaces coated with one or more barrier materials such as calcium carbonate particles. The adhesive compositions exhibit enhanced rheology, sprayability, drying time, tack and storage stability as compared to analogous adhesives that are not modified with coated hollow polymeric microspheres. Such compositions are useful as both contact adhesives as well as wet bonding one-way adhesives.

Multilayer film prepared by a layer-by-layer process that is an effective barrier for humidity and oxygen.

A security element, preferably a security wire, for a secure document, that may include a masking structure for reducing the visibility of a surface of the element when the latter is located inside the document or on the surface of the document, the masking structure comprising a nanometric filler and a multilayer interference pigment.

Described herein are coating systems for preparing multi-layered finishes, multi-layered finish coated substrates, and methods of applying multi-layered finishes to substrates. A coating system for preparing multi-layered finishes includes a base coating component and a clear coating component comprising effects particles. An additional coating system for preparing multi-layered finishes includes a base coating component, a printed coating component, and a clear coating component.

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

A roofing system including a roof deck and a membrane assembly secured to the roof deck. The roof deck may be a flammable roof deck. The membrane assembly includes a roofing membrane and a fire resistant sheet, the fire resistant sheet, or a portion thereof, secured to the membrane. The fire resistant sheet includes a fabric substrate and a binder.
