Product description:
TEROSON® BOND 120 is a one-component polyurethane windscreen adhesive. Both skin formation and curing times are dependent on humidity and temperature. The cure time may vary depending on the joint depth. By increasing the temperature and humidity, the reaction time can be reduced. Low temperature as well as low moisture slows down the process. It has an excellent adhesion to glass, glass with the ceramic coating, encapsulation and to painted surfaces in connection with primer / activator. Typical applications include the bonding of front, rear and side screens to the body of passenger-, utility-, special- and rail vehicles.

Directions for use:

Pre-treatment:
1. The substrate to be bonded must be dry and free from oil, dust, grease and other contaminations.
2. Check the new windscreen for damages or scratches and make sure it fits.
3. To obtain an optimal adhesion on the new screen we recommend 2 different surface preparation methods (solvent-based, TEROSON® VR 10 or water-based, TEROSON® BOND GLASS CLEANER):

Solvent-based Cleaning Process:
a. Wipe off surface with a lint free cloth and TEROSON® VR 10.
b. Abrade bond line with a smooth abrasive pad or wetted TEROSON® BOND SPONGE.
c. Wipe off surface again with a lint-free cloth and TEROSON® VR 10.

Or

Water-based Cleaning Process:
a. Clean surface with TEROSON® BOND GLASS CLEANER
b. Abrade bond line with wetted TEROSON® BOND SPONGE.
c. Apply TEROSON® BOND GLASS CLEANER again and dry off the bond line in one direction using a lint free cloth.

4. Wait at least 2 minutes after the cleaning process to allow all remaining residues to evaporate.
5. Cleaning of the cut adhesive layer remaining on the window aperture is in general not necessary. If, however, cleaning of this remaining layer is needed, an evaporation time of at least 2 minutes is mandatory.

Priming:
1. Before opening the TEROSON® BOND ALL-IN-ONE PRIMER bottle, shake well (at least 1 minute).
2. Apply primer with wool dauber in one pass on the bond line (allow to flash off for 2 minutes).
3. Within the first 2 hours after cutting back the old adhesive bead in the body frame, it does not need to be primed. But if the replacement takes longer than 2 hours, the old cut bead needs to be activated with TEROSON® BOND ALL-IN-ONE PRIMER. NOTE: Provided that it is not contaminated with dust or grease, the old cut adhesive bead is the best adhesive surface for the TEROSON® BOND 120 adhesive.
4. If windows are bonded which have been pre-coated with a primer or PU–based adhesive/sealant by the glass supplier, TEROSON® BOND ALL-IN-ONE-PRIMER is also suitable to ensure the correct adherence of TEROSON® BOND 120 to the pre-coating.
5. Using a wool dauber, a thin layer of TEROSON® BOND ALL-IN-ONE-PRIMER is applied to the pre-coating. Allow to flash off for 2 minutes. Subsequently, TEROSON® BOND 120 is applied as usual, but taking into consideration the layer thickness of the pre-coating. Alternative pre-treatment with a glass activator:

a. Apply TEROSON® BOND ACTIVATOR on the ceramic frit of the windscreen to be bonded. An even wet film must be visible.
b. Let the TEROSON® BOND ACTIVATOR evaporate for minimum 5 minutes at 10 to 35°C. If the UV transmission rate should be lower than 99.9% at the bond line, use a black primer to ensure the UV protection of the adhesive.

Application:
1. The windscreen adhesive TEROSON® BOND 120 is best applied both in cartridge and foil pack using commercial equipment such as hand, battery driven or air-pressure dispensers with a piston rod.
2. The Safe Drive-Away Time of TEROSON® BOND 120 must be respected.
