Abstract:
Films comprising a resin matrix, an entanglement polymer, and a latent curative, wherein the resin has a functionality of at least 2.0 and a viscosity of at least 0.1 Pascal-seconds, and the film is dimensionally stable at 25° C. The films are particularly useful for the bonding of elastomers to rigid substrates, such as rubber to metal, and contain no volatile organic compounds (VOCs), and are shelf stable for extended periods of time.
Abstract:
The branch piece is for renovating a pipeline and has a main line pipe and at least one branch pipe connected with the main line pipe. The branch piece is elastic and has an inner sheathing, an outer sheathing and, at least on a part of the branch piece, a flexible reinforcement layer disposed between the inner sheathing and the outer sheathing. The branch piece regains its shape after compression.

Abstract:
An adhesive sheet includes an adhesive composition layer. The adhesive composition layer is formed using a composition including a polythiol compound, a compound having plural epoxy groups, a radical generator and an amine-based catalyst. The ratio (Ep/SH (epoxy groups/thiol groups ratio)) of a total molar number (Ep) of epoxy groups contained in the compound having plural epoxy groups to a total molar number (SH) of thiol groups contained in the polythiol compound is higher than 0.20 but lower than 1.00.
