摘要:
The present invention relates to a method for sealing the edges of photovoltaic modules, comprising the steps of i) providing a photovoltaic module 12 by applying at least one photovoltaic laminate 1 to a carrier 8; ii) treating the photovoltaic module produced in step i) along the edge region of the photovoltaic laminate by means of a plasma pretreatment or by flame application by means of a gas flame, such that both the edge region of the photovoltaic laminate and, at least partially, the carrier is detected by the plasma pretreatment or the flame application; and iii) applying a sealing mass 9 at least partially to the pretreated location, wherein the sealing mass is a silicone composition or a composition based on silane-terminated poly(meth)acrylates.

The invention relates to humidity hardening compounds containing at least one polyurethane polymer, P, exhibiting an isocyanate group, at least one polyimine ALD of Formula (I) of at least 22% by weight, in relation to the sum of the components of the compound which contain the isocyanate group, as well as, if necessary, a polyisocyanate oligomer OP. The humidity hardening compound is particularly suitable for providing coatings and linings. The use of the imines makes possible VOC-free or VOC poor compounds, which is a substantial advantage for indoor applications.

The present invention relates to the use of a composition Z (3) comprising at least one epoxy resin A, at least one curing agent B for epoxy resins and also zinc particles as cathode corrosion protection for reinforcements of reinforced concrete structures (2). The composition is here applied to the reinforcing steel (1) at certain points and is suitable as corrosion protection for reinforcements of reinforced concrete structures both when erecting and repairing such a structure.
摘要:
A solid thermally expansible material is provided. The material includes a solid epoxy resin that is substantially free of liquid epoxy resin and semi-solid epoxy resin. The material also includes an impact modifier, a curing agent and a heat-activated foaming agent. The impact modifier includes rubber in one embodiment and is substantially free of rubber in another embodiment. Following heat activation, the material expands and can adhere to a substrate. A cured expanded reinforcement material is also provided, as is a method of reinforcing a substrate.
摘要:
A method for installing a constrained layer damper on a product of manufacture is disclosed. The method includes applying a layer (16A) of first polymeric material to a substrate (10) of the product, wherein the first polymeric material is visco-elastic when solidified. Then, a second layer (16B) of polymeric material, which is stiff when solidified, is applied to the first polymeric material such that said first polymeric material is constrained between the second polymeric material and the substrate of the product. At least one of the layers of polymeric materials is dispensed in fluid form during the manufacture of the product from a bulk source of fluid material. The polymeric materials are chosen such that they do not require the application of heat above room temperature to solidify.
摘要:
A structural reinforcement material (20) is provided that includes a base material selected from the group consisting of thermosets, low viscosity thermoplastics with short transition phases and low viscosities, low melting point metallic alloys, and combinations thereof. At STP, the structural reinforcement material (20) is a solid or a formable dough or a mixture thereof. When heated to an activation temperature, the structural reinforcement material (20) becomes flowable into a cavity (10). Following cooling, the structural reinforcement material (20) is a solid or a thermoset with a strength sufficient to reinforce the cavity (10). A structural reinforcement insert (111) comprising the structural reinforcement material (20) is also provided, as is a reinforced cavity (10) of an automobile (2) and a method of reinforcing a cavity (10).
