  • Publication number: 20210379882
    Abstract: A marking tape for application on pavement which comprises a core layer and an adhesive layer outside the core layer. The core layer is formed of a combination of a conforming layer of a thermoplastic material, a marking layer of a cross-linked material, and a fibrous layer. The conforming layer and the marking layer are contiguous and/or directly interconnected with each other. The marking tape is preferably relatively light weight and relatively inexpensive.

  • Publication number: 20140374000
    Abstract: A method of making a decoration comprising a plurality of discrete units of colored adhesive film, the colored adhesive film comprising a PVC film having on one side thereof an adhesive layer protected by a release liner, with a primer layer arranged between the PVC film and the adhesive layer and comprising an aminoplast and a polyester and/or a curing product thereof, the method comprising: * (i) providing the colored adhesive film; * (ii) cutting the PVC film, the primer layer and the adhesive layer to define said plurality of discrete units, * (iii) delaminating the cut portions from the release liner so as to leave the discrete units on said release liner; * (iv) applying an adhesive application tape over said discrete units; * (v) removing the release liner thereby leaving the discrete units attached to the application tape * (vi) applying the application tape with the discrete units to a surface to be decorated with the discrete units facing the surface; and * (vii) removing the application tape.

  • Publication number: 20110177242
    Abstract: Two-part adhesive compositions are described. The two-part adhesives have a first part and a second part, said composition comprising at least one aromatic epoxy resin in the first part; at least one amine curing agent in the second part; and at least one ester in at least one of the first and/or second part. The ester corresponds to the general formula R2—CO—OR1; wherein R1 is an organic moiety comprising at least one of (i) at least one epoxy group or (ii) at least one acryl group and R2 is a branched alkyl group. The structural adhesive may be used to form bonded joints between adherents having clean surfaces, as well as those having surfaces contaminated with hydrocarbon-containing materials, such as oils, processing aids and lubricating agents.

  • Patent number: 6872279
    Abstract: The present invention relates to a sprayable hotmelt adhesive composition, a process for preparing the same, and a method of using the same. The hot melt adhesive composition contains 30 weight percent to 70 percent of one or more poly-?-olefins; 5 weight percent to 30 weight percent of at least one oil; and 20 weight percent to 60 weight percent of at least one hydrocarbon resin having a softening range of 70° C. to 140° C. The poly-?-olefin or the mixture of poly-?-olefins has a softening point of 70° C. to 30° C. and a melt viscosity at 190° C. of 1,000 mPas to 20,000 mPas. The hotmelt adhesive has a viscosity at 150° C. of 500 mPas to 4,000 mPas.
