Provided is an acrylic emulsion pressure-sensitive adhesive composition, and more particularly, an acrylic emulsion pressure-sensitive adhesive composition which may realize excellent adhesive properties, and may maintain excellent adhesive strength even after aging, in particular, when applied to a curved surface of an adherend, and thus may be usefully applied to labels for bottles, etc.

Acrylic emulsion pressure-sensitive adhesive composition

A hot-melt adhesive composition includes a styrene-butadiene-styrene triblock copolymer and a styrene-isoprene-styrene triblock copolymer. The hot-melt adhesive composition enables melt processing at a relatively low temperature because of having a low viscosity properties are property and thus exhibits excellent adhesive strength and heat resistance while improving the processability. In particular, the melt adhesive composition has excellent mechanical properties after curing, and thus can be used in various industrial fields.

Hot melt adhesive composition

Provided are an optical member, a pressure-sensitive adhesive composition, and an LCD. The optical member may have excellent endurance reliability even when a pressure-sensitive adhesive layer is formed to have a thickness of 20 &#x3bc;m or less.

Optical member, pressure-sensitive adhesive composition and liquid crystal display

Provided are a pressure-sensitive adhesive composition, a pressure-sensitive adhesive optical laminate, a pressure-sensitive adhesive polarizing plate and a display device. The pressure-sensitive adhesive composition offers a pressure-sensitive adhesive that has excellent durability and processability in manufacturing due to increased hardness even when the pressure-sensitive adhesive layer is formed thinner than a typical adhesive composition, and that can prevent a pressure mark and leakage of the pressure-sensitive adhesive, as well as a bending problem generated when applied on an optical member such as a polarizing plate, etc.

Pressure sensitive adhesive composition

The present invention relates to a protective film, a conductive laminate including the protective film, and a polarizing plate including the protective film, and provides the protective film which has peel strength controlled to be low, thus allowing for an easy removal of the protective film, which has an excellent polymerization stability and pot life, and may prevent a problem of an additive transfer to an adherend due to the additive.

Protective film

Provided are a display panel, a backward diode equipped on a bottom surface of the display panel, a packaging film for packaging the backward diode, and a pressure-sensitive adhesive layer formed between the display panel and the packaging film. The packaging film includes a first region corresponding to a top surface of the backward diode, and a second region extending from the first region and corresponding to a side surface of the backward diode. Due to the display device, a bezel region can be minimized.

Display device

Provided are a method of manufacturing a high silica zeolite using a recovered silica filtrate, and a high silica zeolite manufactured according to the method. To this end, the present invention provides the method of manufacturing the high silica zeolite using the recovered silica filtrate, including manufacturing a solated agglomerated silica from the silica filtrate including a metal salt (step 1); filtering and washing the solated agglomerated silica of step 1 to manufacture a silica cake from which the metal salt is removed (step 2); peptizing the silica cake to manufacture a silica sol (step 3); and manufacturing the high silica zeolite using the silica sol manufactured in step 3 as a silica source (step 4). Further, the present invention provides a high silica zeolite manufactured from a recovered silica filtrate through the manufacturing method and having a Si/Al mole ratio of 5 or more. According to the present invention, it is possible to provide a process of manufacturing a high silica zeolite, in which economic feasibility, a manufacturing cost, and a manufacturing time of process steps are reduced, by reusing a recovered silica filtrate to manufacture the zeolite.

Disclosed is an adjuvant capable of imparting a hydrophilic or superhydrophilic function to various materials or interfaces. The hydrophilic adjuvant comprises: a composite metal oxide containing Si and at least one metal element selected from the group consisting of Ti(IV), Zr(IV), Sn(IV) and Al(III); and a hydrophilic group-containing organic compound physically or chemically bonded with the Ti(IV), Zr(IV), Sn(IV) or Al of the composite metal oxide.

Hydrophilic adjuvant

Disclosed is an organic/inorganic composite electrolyte membrane comprising: (a) a sulfonated fluorine-free hydrocarbon-based polymer; and (b) inorganic particles capable of collecting moisture, wherein the inorganic particles include zeolite. Also, disclosed are an electrode comprising the zeolite as a component for forming a catalyst layer, a membrane electrode assembly comprising the electrolyte membrane and/or the electrode, and a fuel cell having the membrane electrode assembly. The organic/inorganic composite electrolyte membrane using the hydrophilic zeolite in combination with the sulfonated fluorine-free hydrocarbon-based polymer shows high proton conductivity, and thus can impart excellent quality to a fuel cell even under high-temperature and low-humidity conditions.
