摘要:
A bonding system for bonding a plastic substrate to another substrate, the bonding system comprising a plastic substrate wherein the plastic substrate is impregnated with a transition metal; and an anaerobically curable composition. Cure of the anaerobically curable composition is initiatable by the transition metal when the anaerobically curable composition is contacted with the plastic substrate under anaerobic conditions.

An article includes a plurality of stacked sheets. Each sheet includes a film having a first side, with a print receptive or primed layer, and a second side, with an optional release treated layer; and a bonding layer that is coated at 100% solids on the first side of the film to releasably attach a second side of a film of an overlying sheet to the first side of an underlying sheet. Each sheet is stacked upon another sheet such that except for a topmost sheet of the stack the bonding layer is in contact with the second side of a film of an overlying sheet. The bonding layer of the topmost sheet defines an outer surface of the stack that protects the topmost sheet of the stack from environmental damage.
摘要:
To provide a heat-expandable removable pressure-sensitive adhesive tape that maintains a high normal adhesive strength during bonding as well as can be readily separated or debonded by heat for separation or debonding even after the storage or use for a long time, regardless of an adherend type. The heat-expandable removable pressure-sensitive adhesive tape of the present invention includes at least a blowing agent-containing pressure-sensitive adhesive layer A, a microparticle-containing viscoelastic substrate B, a peelable or peel-assisting film layer C, and a pressure-sensitive adhesive layer D. A multilayer structure containing at least the peelable or peel-assisting film layer C and the pressure-sensitive adhesive layer D is arranged on at least one side of the blowing agent-containing pressure-sensitive adhesive layer A where the blowing agent-containing pressure-sensitive adhesive layer A is in direct contact with the peelable or peel-assisting film layer C. The peelable or peel-assisting film layer C can be removed from the blowing agent-containing pressure-sensitive adhesive layer A by heat treatment after storage in an atmosphere of 75°C for 8 weeks.
摘要:
Bei dem Verfahren zum Verbinden zweier Teile besteht der eine Teil (Primärteil) aus einem anorganischen Werkstoff, aus einem kratzfest beschichteten Polykarbonat oder aus einem Polypropylen (PP) und der andere Teil (Sekundärteil) aus einem Polypropylen (PP). Bei dem Sekundärteil wird die Oberfläche zumindest des Verbindungsbereiches durch eine Vorbehandlung aktiviert, bei der die Oberflächenspannung des PP erhöht wird. Bei einem aus PP bestehenden Primärteil wird ebenfalls die Oberfläche zumindest des Verbindungsbereiches durch eine Vorbehandlung aktiviert, bei der die Oberflächenspannung des PP erhöht wird. Auf den Verbindungsbereich des Primärteils oder auf den Verbindungsbereich des Sekundärteils wird ein Klebstoff aufgetragen, der ein MS-Polymer oder ein silan-modifiziertes Polyurethan (SMP oder Hybrid) ist. Der Primärteil und der Sekundärteil werden mit ihren Verbindungsbereichen aneinander angedrückt und miteinander verbunden.
