Attributes: Gudy 831 is not an adhesive film but rather a double-sided adhesive non-woven paper which only has a release liner consisting of siliconized paper on one of its sides which is wound on itself and therefore is only available in rolls. Its aqueous dispersion based acrylate adhesive is aging resistant, will not yellow, will not become brittle, will not bleed through, is pH neutral and is produced in an ecologically friendly manner without solvent. We will be glad to send you a sample (about A5) upon request.
Applications: Gudy 831 lends itself to being worked with by hand and can be applied to many smooth, rough and flexible substrates (e.g. uncoated particle board, plastic sheets). It is especially good for bonding paper to both cardboard and paperboard because in the process all the bonded components have similar attributes and the chances of warping are less than when using adhesive film.
Application: Posters, layouts, photographs, blueprints or maps can be firmly attached to suitable surfaces with adhesive film, adhesive with non-woven paper centres or transfer film. All types of panels with smooth surfaces like CARDBOARD, KAPA BOARDS or PLASTIC SHEETS can serve as the substrate material. Please note: Alternatives to double-sided adhesive films or double-sided adhesive non-woven paper include SPRAY ADHESIVE, TRANSFER ADHESIVE, XYRON adhesive and laminating machines, standard ADHESIVE NON-WOVEN ADHESIVE or GUDY 870, and, finally, self-adhesive panels like, for example, KAPA FIX.
Processing: Working with the double-sided adhesive film by hand is done as follows: the film is mounted by applying it from one corner to the other and made secure and smooth with the help of a sqeegee-type applicator during which time the the release liner paper is simultaneously and gradually removed as required for exposing the adhesive. Before the PE film liner is removed at a sharp angle, any bubbles should be punctured with a NEEDLE and smoothed out.
The same procedure applies to all the Gudy products. Because, however, only one of their sides has a protective liner, more care must be taken when working on larger areas in order to prevent the adhesive side from sticking to places where it shouldn’t.
Applying your object to the prepared substrate requires a certain amount of dexterity because double-sided adhesive films are very clingy (like plastic wrap). Once the paper has been placed on the film, it must sit perfectly. Large folds or creases cannot be remedied or removed because the paper can no longer be separated from the film. Here too, you can work radially from the middle of a side outwards and do the necessary pressing with a soft brush or cloth.
