  1. 1. Technical Data Sheetgudy® windowGudy window is a self-adhesive thin clear polyester film coated on both sides with solvent-free, age resistantand permanently elastic acrylate adhesive which doesn’t dry out or become greasy.Applicationgudy® window is coated with a strong, permanent adhesive on the paper marked side. The other side allowsreversible short to mid-term face mounting of photographs, prints, drawings, charts or other images on smooth,clean and greese-free backing surfaces made of glass. gudy® window can easily be applied by hand. Printsgenerally can be removed from the glass surface without residues. Under certain conditions occurring residuescan very easily be removed with petrolether (b.p. 60º - 80º C/ 140º - 194ºF). For removing residues of thepermanent adhesive usage of alcohol is recommended.

All data are standard values.The information in this specification sheet is based on findings obtained in practice. Because of the high numberof factors which can have an effect during handling and application, customer test will also be required. Asgudy® window is used to join two materials whose structure may vary greatly, their properties and their effect onthe quality of the adhesion have to be taken into account. Thus the given product life refers only to the productitself. The possibility of residue-free removal will have to be checked before each new application. Damage tothe carrier can not always be ruled out. A legally binding guarantee of specific properties is not to be inferredfrom our specifications.Neschen Americas, 7091 Troy Hill Drive, Elkridge, MD 21075Telephone: 410-540-8900 Fax: 410-579-8960 www.neschenamericas.com March 2006
  2. 2. Technical Installation Guidegudy® window Gudy® Window Technical Information and Installation Guide Introduction: New from Neschen is a visually clear mounting adhesive designed for installing large images by hand o location. gudy® Window is a double-sided mounting adhesive designed for fast, easy bubble free face mounting to glass utilizing a simple hand squeegee. This product consists of a 1mil clear polyester film with an aggressive adhesive on one side and a removable on the other. The adhesive is produced with micro grooves allowing for easy evacuation of all air bubbles and is specially formulated for easy removal without leaving any residue. The adhesive is very re-positionable. Other applications include promotional graphics for glass cooler doors in grocery stores, back-lit display cabinets in airports and sports arenas as well as a variety of P.O.P. displays. gudy® Window is ideal for all temporary situations or where installation is required on sensitive surfaces. gudy® Window is designed primarily for short-term uses. Any other applications or installations not described in this update are the responsibility of the installer to determine the specific characteristics and or consequences. For all installations care must be used when removing the release liner as not to inadvertently remove any adhesive with it. In the advent small sections of adhesive comes of with the liner the graphic can still be successfully installed without any visible discrepancies in the image. On Glass Windows: Windows should be cleaned with soap and water, thoroughly rinsed with clear water and wiped dry. Window cleaning solutions are not recommended. If used be sure the window is completely dry and wiped down with a dry, clean towel. The low tack adhesive is designed for excellent re-positioning of the initial installation. Graphics may be repositioned six to ten times successfully without any changes to the original structure of the micro grooves in the adhesive. This also depends on the amount of squeegee pressure (normally very little is required). Once the graphics have been in place for a period of 24 hours the adhesive becomes more aggressive and should not be disturbed until the graphic has completed its function. The normal life expectancy when mounted on the interior of glass windows with moderate direct sun is between 2 and 3 months. While there are some UV inhibiting characteristics in gudy® Window, Neschen does not guarantee the color-fastness of the image for this period of time. Moisture condensation can result in product failure. If graphics are installed in an area that is known to have this condition, because of the low tack nature of gudy® Window, it is advised that the edges be sealed to prevent moisture penetration. If unchecked the result will be a white milky discoloration in the graphic. This condition will however disappear once all the moisture has dissipated. The graphic will return to its original clarity. Clear Acrylic Sheet…Not Recommended! Due to the nature of many types of acrylic sheet the low tack adhesive may be affected by moisture inherent to the plastic sheet. Face mounting to these products is not recommended unless the acrylic has been thoroughly cured by special drying techniques. Contact the manufacturer for further information.
