The invention relates a process for the preparation of a bonded structure (4) comprising at least a first plastic part (1) having a first bonding surface (1a), said process comprising the step of a) treating at least part of a first bonding surface of said first plastic part with a flame of a propane-comprising gas, said propane-comprising gas being propane or a mixture comprising at least 50 wt. % of propane based on the weight of the propane-comprising gas with one or more gases selected from the group consisting of methane, ethane, butane, pentane, and hexane, wherein, during treatment with a flame of the propane-comprising gas, a flame is produced by burning a mixture of air and the propane-comprising gas, wherein the gas-to-air ratio is chosen such that the propane gas to oxygen volume ratio is equal to or less than 1:5.01, for example less than 1:5.00 and preferably at least 3.50 to obtain a first plastic part having a flame-treated first bonding surface.

The present invention relates to a method of producing a bonded body in which members are allowed to bond to each other with a yarn-like adhesive body, and at least a part of a bonding region, which is a portion where members are allowed to bond to each other, has a bent shape, and the members are allowed to bond to each other with the yarn-like adhesive body bent according to a shape of the bonding region.

Proposed are a method of manufacturing a polarizing film and the polarizing film thereto that is not harmful to the human body by making the surface of a PC film hydrophilic, and laminating it with a PVA film using water-based adhesive on the surface of the hydrophilic PC film, in manufacturing the polarizing film by laminating a polycarbonate (PC: polyvinyl alcohol) film and a polyvinyl alcohol (PVA: polyvinyl alcohol) film constituting the polarizing film.

The present disclosure is directed to a composite material comprising a thermoplastic adhesive and nanotubes oriented in the in-plane orientation. In additional aspects, the disclosure includes a laminated armor material comprising the composite and armor materials.

The present disclosure relates to laminated armor materials for enhanced ballistic protection. In particular, the present disclosure relates to laminated armor materials comprising first and second armor materials and a laminated adhesive layer comprising nanomaterial fillers.

Disclosed are UV curable adhesive compositions and methods to adhere polycarbonate substrates containing UV absorbers to glass for use in ophthalmic lenses.

The present invention includes: a photochromic adhesive composition containing (A) a photochromic compound having, as a substituent, a molecular chain having a molecular weight of 300 or more, and (B) an adhesive urethane (urea) resin, and having a softening point of 140 to 220° C., and a photochromic laminate using the adhesive composition.
