3.6 Pre-treatment of new window glass

• Apply a thin coat of glass activator (yellow stick); a final wipe is not necessary.
• Observe an air drying time of at least 2 minutes

The glass activator is used for adhesion between glass or ceramic glass and the adhesive. Therefore, a thin, homogeneous and continuous line of glass activator must be applied. If the window glass is to be reused with a cut-back adhesive bead, glass activator is not needed.

It must be ensured that a 1 to 2 mm wide line of bonding agent is located on the ceramic glass next to the squeezed adhesive bead.

The adhesive bead may become up to 15 mm wide in compressed condition. The width of the adhesion agent is therefore at least 17 mm with windscreens and rear windows and at least 9 mm with side window.

The glass activator may not be applied in the field of view or the point grid. Fresh glass activator in the field of view must immediately be wiped off with cleaning agent R2 because hardened glass activator will leave a haze behind.
