Abstract: A two-part polyurethane composition including a first pack and a second pack. The first pack includes at least one hyperbranched copolymer having OH groups and which is prepared from at least one or more monomer(s) having at least two unsaturated C—C bonds and one or more monomer(s) having one unsaturated C—C bond and one hydroxyl group in the presence of a cobalt (II) complex. The second pack comprises at least one polyisocyanate. Disclosed is a two-part polyurethane composition which has low viscosity, long pot life, fast cure, excellent weathering and UV resistance and which is suitable for use as a coating.

Abstract: A composition including at least one curable structural adhesive, and at least one chemically cross-linked elastomer, wherein the chemically cross-linked elastomer is present in the structural adhesive as penetrating polymer network. Such a composition constitutes a so-called shape memory material and is suitable for reinforcing cavities in structural components, such as, for example, in automobile bodies.

Abstract: Disclosed are various embodiments of expandable barriers. Expandable barriers are typically barriers made from an expandable material and formed to fit within a cavity. After being placed inside a cavity, expandable barriers generally undergo an activation process, where the expandable barrier expands to fill the cavity and create a physical barrier. Using various extrusion processes to form an expandable barrier allows for a reduction in tooling costs, while also allowing more flexible barrier designs. Such designs can be specifically tailored for a particular cavity or cavities to ensure that the barrier fills the cavity after expansion.

Abstract: The current invention relates to a moisture-hardening composition that contains, in addition to a silane-functional polymer with end groups of formula (I), a reaction product that can be manufactured from an amino silane with primary amino groups and an alkene that is free of silane groups. The compositions are characterized by improved expandability with concurrent high reactivity, good adhesion characteristics, and high tear strength and are suited especially for use as elastic bonding substance or sealant.

Abstract: The disclosure relates to a device and method for introducing a force into tension members made of fiber-reinforced plastic flat strip lamella. The device can include at least one clamping element, which is arranged on the tension member and has at least one contact face with the tension member. At least one rigid sleeve can be arranged around the at least one clamping element and the tension member and thereby exerts a clamping pressure on the tension member via the clamping element. The clamping element can be formed of plastic material having a modulus of elasticity ranging between 1000 and 5000 MPa, bending tensile strength of ?25 MPa and pressure resistance of ?25 MPa.

Abstract: Dialdimines of formula (I) and emulsions and uses thereof. In particular, they can be used for the preparation of pasty curing agent or accelerator components for polymers having isocyanate groups, which lead to very high early strength, which have good flow behaviour on pumping and which can be formulated without VOC solvents, in particular without N-alkylpyrrolidones. These components can be homogeneously or inhomogeneously mixed in an outstanding manner, in particular in a laminar manner, with components which contain polyurethane polymers having isocyanate groups, the two-component compositions thus obtained curing rapidly, having extremely high early strength and remaining without annoying weaknesses.

Abstract: A module is disclosed, which includes a carrier, at least one solar cell disposed on the carrier, and a covering layer that is applied to a side of the at least one solar cell facing away from the carrier. The covering layer includes side lugs, corner lugs, and notches, and wherein one notch each forms a side edge of a side lug or of a corner lug. The side lugs and corner lugs are divided by a corresponding fold line and are disposed on the side of the carrier facing away from the at least one solar cell. The side edges of the corresponding side lugs and corner lugs formed by a notch are in contact with one another.

Abstract: A photovoltaic system including a wedge-shaped carrier and at least one solar cell. The photovoltaic system has an intermediate space for means for electrically connecting the at least one solar cell.

Abstract: A reinforcing element for reinforcement in cavities of structural components including a substrate made of a plastics material, which is at least partially coated with a metal; and a foamable, thermosetting structural adhesive which is applied to the metal coating of the substrate; or a thermosetting structural adhesive which is applied to the metal coating of the substrate and is designed as a shape memory material.
