    These rely on adhesive material affixed to a backing such as paper or plastic film. [1] Because of the inherent tackiness of the adhesive material and low surface energy, these tapes can be placed onto a variety of substrates when light pressure is applied, including paper, wood, metals, and ceramics.

  3. Polyvinyl acetate - Wikipedia

    As envelope adhesive. As wallpaper adhesive. As a primer for drywall and other substrates. As a gum base in chewing gum. [8] As a water-soluble support material for 3D printing, usually for the fused filament fabrication method. [9] As an adhesive for cigarette paper. [10] As the coating layer on Gouda cheese. [11]

  4. Surface chemistry of paper - Wikipedia

    en.wikipedia.org/wiki/Surface_chemistry_of_paper

    This phenomenon is when ink is unable to transfer to the paper because of the water layer at the surface. The contact angle value for hydrocarbons on a rough pigment-coated paper can be found to be approximately 110° through a contact angle meter. The Young's equation can be used to calculate the surface energy of a liquid on paper. Young's ...

    2) The first layer of coating to even out the surface 3) A second layer for an even smoother and whiter surface. Pigments that absorb in the yellow and red part of the visible spectrum can be added. As the dye absorbs light, the brightness of the paper will decrease, unlike the effect of an optical-brightening agent. To increase whiteness, a ...

  6. Pressure-sensitive tape - Wikipedia

    en.wikipedia.org/wiki/Pressure-sensitive_tape

    The primary component of tape upon which an adhesive is applied. Examples are cloth, paper, metal foil, plastic film, etc. Conformability. Ability of a tape to make total contact with a rough or uneven surface. Creped. Paper that has small "folds" to provide stretchability and conformability. Double-coated, or two-sided tape. Pressure-sensitive ...

  7. Surface treatment of PTFE - Wikipedia

    en.wikipedia.org/wiki/Surface_treatment_of_PTFE

    In adhesion tests per ASTM D4541, in which an aluminum stud is bonded to the test surface and the stud is pulled in the direction normal to the surface, both surfaces of the failure interface were analyzed by X-ray photoelectron spectroscopy (XPS). F/C ratio was used as an indicator of the failure mode: F/C of zero corresponds to failure in the ...

    In this case, the adhesive remains intact and is still bonded to one substrate and remnants of the other. For example, when one removes a price label, the adhesive usually remains on the label and the surface. This is cohesive failure. If, however, a layer of paper remains stuck to the surface, the adhesive has not failed.

  9. Paint adhesion testing - Wikipedia

    en.wikipedia.org/wiki/Paint_adhesion_testing

    In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
