摘要:
The invention relates to an adhesive tape, especially for producing or gluing optical liquid crystal displays (LCDs). Said tape comprises an upper face and a lower face with at least one layer of an adhesive compound (c, c′) and at least one support film (a) having an upper face and a lower face. The invention is characterized in that the support film has translucent properties.
摘要:
A pressure-sensitive adhesive (PSA) tape, particular for producing or bonding optical liquid-crystal data displays, having two PSA layers (b, b′) and at least one carrier sheet (a), wherein the PSA tape has light-reflecting properties on both its top and bottom faces and at the same time is light-absorbing at least in so far as light not reflected is unable to penetrate the adhesive tape. The PSA tape is implemented in particular in such a way that at least between one face of the carrier sheet and the PSA layer located on that face there is a white paint layer (c). As a preference, a metallic layer (d) is provided between the carrier sheet and the white paint layer.
摘要:
A pressure sensitive adhesive tape for producing or bonding optical liquid crystal data displays (LCD's) is disclosed. The pressure sensitive adhesive tape is constructed of an upper side and an underside, as well as a carrier film with an upper side and a lower side. At least one pressure sensitive adhesive layer is applied to both the upper and lower side of the adhesive tape. The adhesive tape also includes at least two black layers on one side of the carrier film between one of the outer pressure sensitive adhesives, and a silver-colored layer between the two black layers.
摘要:
The invention relates to the use of an adhesive film for bonding a chip module in a card body. Said adhesive film comprises at least two adhesive layers (i) and (ii), which differ chemically from one another.
摘要:
The invention relates to an adhesive film comprising at least two adhesive layers (i) and (ii), which differ chemically from one another. The inventive film is characterized in that one layer (i) is suited to bond with epoxy materials and/or polyimides-and the other layer (ii) is suited to bond with polycarbonate, polyethylene, polypropylene, acrylonitrile-butadiene-styrene copolymer plastics, polyethylene terephthalate and/or polyvinylchloride.
摘要:
A self-adhesive article made from a sheet or strip support at least partly coated on at least one side with a pressure-sensitive adhesive material based on polyacrylate, comprising at least one polyacrylate block copolymer with a sequence of hard polymer blocks [P(A)], having a glass transition temperature of not more than 10° C., preferably of 0 to −80° C. and of soft polymer blocks [P(B)], having a glass transition temperature of more than 10° C., preferably 20 to 175° C. A microstructuring is thus generated, which permits the exchange of the smallest adhering and non-adhering regions and thus generates the desired easily stuck and easily removed adhesive action such as required for self-adhesive note pads.
摘要:
A method for gluing plastic parts, especially Flexible Printed Circuit Boards (FPCB's), with a thermally-activated adhesive comprising at least one thermoplastic polymer or a modified rubber and at least one resin.
摘要:
A pressure-sensitive adhesive based on at least 50% of one or more block copolymers, at least one block copolymer being composed at least in part on the basis of (meth)acrylic acid derivatives, the at least one block copolymer comprising at least the unit P(A)-P(B)-P(A), comprising at least one polymer block P(B) and at least two polymer blocks P(A), where P(A) independently of one another represent homopolymer or copolymer blocks made up of monomers of group A, the (co)polymer blocks P(A) each having a softening temperature in the range from 0° C. to +175° C., P(B) represents a homopolymer or copolymer block comprising monomers of group B, the (co)polymer block P(B) having a softening temperature in the range from −130° C. to +10° C., and the (co)polymer blocks P(A) and P(B) are not homogeneously miscible with one another at 25° C., characterized in that the adhesive has a refractive index nd,a of nd,a≧1.52 at 25° C., at least one of the (co)polymer blocks P(A) have a refractive index nd,A of nd,A≧1.58 at 25° C., and the (co)polymer block P(B) has a refractive index nd,B of nd,B≧1.43 at 25° C.
摘要:
Process for UV-initiated thermal crosslinking within a hotmelt process for the preparation of polyacrylate hotmelt adhesives, in which a polymer is produced from an acrylate-based comonomer mixture that includes monomers which carry at least one functional group capable of reacting with a photochemically generated base, with or without the addition of a catalyst, and then coating this polymer onto a backing, irradiating within the coating process or thereafter, and finally subjecting the polymer to thermal treatment, with crosslinking occurring between the polymer and the photochemically generated base. Structural crosslinking of the sheetlike pressure-sensitive adhesive can be produced if irradiation takes place through a mask.
摘要:
Pressure-sensitive adhesive comprising an acrylate block copolymer having at least two chemically distinguishable, covalently interlinked acrylate polymer blocks P in microphase-separated regions and each having a softening temperature of between −125 and +20° C.
