Abstract:
A protection sheet is provided for application to a vehicle window plate to protect the window plate. Protection sheet includes a substrate and a PSA layer provided on one surface of substrate. Protection sheet has a 30-minute peel strength (S1) of less than 0.10 N/20 mm and a 48-hour peel strength (S2) of 0.05 N/20 mm or greater when applied to a glass plate by a wet application method where water is provided to the surface of the glass plate and protection sheet is press-bonded to the glass plate while pushing the water present between the glass plate surface and PSA layer to the outside of the bonding area.
Abstract:
The invention describes a preparation process of pressure sensitive adhesives, wherein a multi-stage emulsifier-free emulsion polymerization and applications of the obtained dispersions for pressure sensitive protective films are included. At least one carboxylic acid group containing monomer is used in the first stage of emulsion polymerization. The theoretical glass transition temperatures are lower than 0° C. (for the first stage polymer), −20° C. (for the second stage polymer) and −15° C. (for the overall dispersion), respectively. The dispersion is preferably cross-linked with polyfunctional crosslinking agents, such as aziridine, isocyanate, carbodiimide and oxazoline. The adhesives obtained from the process thereof can be used for the application of protective films to reduce or eliminate ghost shadow on the protected surfaces.

A readily removable film containing a substrate layer (A) and a readily removable layer (B), wherein the substrate layer (A) contains a thermoplastic resin, the readily removable layer (B) contains from 30 to 60% by weight of a mixture of a crystalline polypropylene resin having a degree of crystallinity of at least 65% and a thermoplastic resin immiscible with the crystalline polypropylene resin, and from 40 to 70% by weight of a fine powder, in which the thermoplastic resin immiscible with the crystalline polypropylene resin is blended in a ratio of from 105 to 300 parts by weight relative to 100 parts by weight of the crystalline polypropylene resin, and the readily removable layer (B) is stretched at least monoaxially.
Abstract:
A thermal laminating film is provided that has superior intrusion resistance that is well suited to addressing security and anti-counterfeiting needs. The film includes a polymer substrate and an adhesive system with a polymer component having a Vicat softening point temperature that is close to a glass transition temperature of the polymeric substrate, which typically is not greater than about 95° C.
Abstract:
Provided are a pressure-sensitive adhesive composition, a protective film, an optical device, and a display device. The pressure-sensitive adhesive composition may exhibit suitable low speed and high speed peel-off strengths after forming a crosslinking structure, and have an excellent balance between them. Accordingly, the pressure-sensitive adhesive composition may exhibit an excellent protective effect when applied to a protective film, may be easily peeled in a high speed peel-off and thus advantageous for the high speed process, and may exhibit an excellent antistatic characteristic.
Abstract:
Compositions which are well suited for forming into machine direction orientation (MDO) films are described. Multilayer films containing one or more layers of the compositions and/or films are also described. Additionally, label assemblies utilizing the multilayer films, labeled substrates, and related methods are described. Various versions of the multilayer films are described including films having at least two skin layers and an interior core layer. Particular multilayer films are described having polyethylene rich cores.
Abstract:
The present invention relates to a textile which is capable of being stuck to a transparent surface and which makes it possible to look out of a room with a lower light intensity into a room with a higher light intensity but which prevents looking out of a room with a higher light intensity inside into a room with a lower light intensity. The textile comprises threads characterised in that they have a fibrous character, which are shear-resistant with respect to one another, in such a way that a textile aspect is retained, and wherein an adhesive is applied to the threads on one side in order to apply the textile to a transparent surface, wherein the adhesive is applied such that at least at one side the fibrous character of the threads is preserved.
Abstract:
The present disclosure provides a method of constructing an electrochromic lens which simplifies the steps of applying the electrochromic electrode coatings onto the lens elements. An electrochromic lens is constructed by applying an electrochromic electrode film onto the inner surfaces of facing lens elements and then sandwiching an electrochromic material between the lens elements. The films include a release liner having a release coating, an adhesive coating overlying the release coating of the release liner, an indium tin oxide (ITO) coating overlying the adhesive coating, and an active electrochromic electrode (EE) coating or active electrochromic electrode (ECE) coating overlying said ITO film coating. The release liner is removed and the remaining layers of the film are adhered to the lens.
Abstract:
Disclosed is a pressure-sensitive adhesive tape that uses, as a plasticizer, an alternative compound to bis(2-ethylhexyl)phthalate (DOP) and dibutyl phthalate (DBP), has excellent tackiness, and can be unwound satisfactorily, where DOP and DBP are to be restricted under the REACH regulation. The pressure-sensitive adhesive tape includes a poly(vinyl chloride) substrate and a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is disposed on or over one side of the substrate. The poly(vinyl chloride) substrate contains 10 to 40 percent by weight of bis(2-ethylhexyl)terephthalate. The pressure-sensitive adhesive tape preferably has an unwinding force of 0.4 N/20 mm or less at a tensile speed of 0.3 m/min and an unwinding force of 1.2 N/20 mm or less at a tensile speed of 30 m/min.
