Abstract:
Heat de-bondable adhesive articles include a heat-shrinkable optical substrate with optically clear adhesive disposed on the two major surfaces of the heat-shrinkable substrate. Optical articles can be prepared by disposing the heat de-bondable adhesive articles between two optical substrates. Other optical articles can be prepared by disposing an optically clear adhesive layer and a heat-shrinkable optical substrate on an optical substrate.
Abstract:
The present invention relates to a heat- and moisture-crosslinkable adhesive composition comprising: a) from 40 to 60 wt % of at least one polyurethane obtainable by a polyaddition reaction of at least one particular diisocyanate with at least one polyether diol, with or without the presence of at least one reaction catalyst, at a reaction temperature T1 below 95° C., in anhydrous conditions, and in amounts of diisocyanate(s) and of polyether diol(s) leading to an NCO/OH molar ratio in the range from 1.6 to 1.9; b) from 39 to 59 wt % of at least one compatible tackifying resin and c) from 0.01 to 1 wt % of at least one crosslinking catalyst. The present invention also relates to a method of preparing said adhesive composition, a self-adhesive support coated with the crosslinked adhesive composition and the use of said support for making labels and/or self-adhesive tapes.

Abstract:
The present invention relates to an acrylic pressure-sensitive adhesive composition. More specifically, the present invention relates to an acrylic pressure-sensitive adhesive composition comprising a) acrylic copolymers; b) a hydrophilic plasticizer; and c) a hydrophobic plasticizer. The acrylic pressure-sensitive adhesive composition according to the present invention has no mura under moisture and heat resistant condition, and thus has an excellent stain resistance of adherends, and an excellent wettability, endurance reliability, transparency and adhesion reliability, regardless of whether surface property of the adherend is hydrophillic or hydrophobic.
Abstract:
There is provided a tape comprising a polypropylene backing having a thickness of at least 0.0254 mm and a synthetic rubber pressure sensitive adhesive having a thickness of at least 0.0229 mm, wherein the tape has a ratio of pressure sensitive adhesive to polypropylene backing thickness of at least 0.7:1.
Abstract:
An environment-friendly adhesive composition is provided that includes about 10 to about 70 parts by weight of a tackifying agent base including an acryl-based attaching agent as a raw material, about 5 to about 40 parts by weight of a terpene-based tackiness improver, about 0.5 to about 5 parts by weight of an epoxy-based crosslinking agent, about 5 to about 60 parts by weight of a flame retardant, and a combination thereof, based on 100 parts by weight of a solvent excluding benzene, toluene and xylene (BTX). The flame retardant includes at least one selected from a group consisting of a halogen-based flame retardant, an antimony flame retardant, and a phosphorus-based flame retardant. The adhesive composition and a tape manufactured using the same may be used exclusively in a vehicle industry, and in various electronic industries.

Abstract:
Provided are: a polyester-based pressure-sensitive adhesive composition which can be produced even from plant-derived raw materials with no need of using a costly silicone-based pressure-sensitive adhesive or the like and which is usable for producing a pressure-sensitive adhesive sheet excellent in wettability to an adherend, light peelability, removability, anti-staining property (little adhesive residues), and workability, and to provide a pressure-sensitive adhesive sheet using the composition. A polyester-based pressure-sensitive adhesive composition comprising a polyester obtained by condensation polymerization of at least a dicarboxylic acid having a side chain and an aliphatic diol having 3 to 10 carbon atoms and a crosslinking agent, wherein the polyester has a weight average molecular weight of 5000 to 60000.
Abstract:
Disclosed is a semi-hardened pressure sensitive adhesive film to be used in the semi-hardened state and having excellent printing step absorption properties. The adhesive film according to the present invention contains a radial polymer composition and a cationic polymer composition, and the radial polymer composition is primarily cross-linked to maintain the semi-hardened state. When applied onto a substrate through a printing step, the present invention has excellent step absorption properties and adhesion properties and excellent durability even under high-temperature and high-humidity conditions.
Abstract:
