    Abstract: A stripping liquid of the present invention is used for separating the paper from a plaster/paper laminate such as waste plasterboard, and comprises an aqueous solution of an alkali metal salt or an ammonium salt of carboxylic acid. The stripping liquid is fed onto the surface (paper surface) of the plaster/paper laminate so as to infiltrate into the bonding surface between the plaster and the paper, so that the carboxylate is made present on the bonding surface. Upon stripping off the paper in the presence of the carboxylate, it is allowed to entirely separate the paper from the plaster. Upon mixing the stripping liquid and a nonionic surfactant or a water-soluble organic solvent together, further, the stripping liquid can be quickly and reliably infiltrated into the bonding surface between the plaster and the paper.

  • Patent number: 6989359
    Abstract: Silane type polyfunctional coupling agents and adhesion promoters are added to major amounts by volume of environmentally-safe organic wipe solvents generally having a low vapor pressure to form novel wipe solvent compositions for cleaning and priming the surface of a substrate such as that of metal, composite, glass, plastic or other material prior to the application of coatings of paint, adhesive and/or similar layers and/or prior to the lamination of such substrates to each other or to support structures such as honeycomb bodies, while simultaneously depositing and bonding the coupling agent and adhesion promoter to the cleaned surface of the substrate.

  • Patent number: 6518230
    Abstract: A new solvent formulation is invented for removing cured adhesive and coating. It solves the problem that crosslink polymers only can be swelled, and a mechanical force has to be applied to remove the adhesive. The new solvent can dissolve the UV cured crosslink polymers very fast and clean the substrate meanwhile.
