CURE MECHANISM
SikaTack® DRIVE (Purform®) cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower (see diagram 1).

CHEMICAL RESISTANCE
SikaTack® DRIVE (Purform®) is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents.
Application
Surface preparation
Surfaces must be clean, dry and free from grease, oil, dust and contaminants.
The bond faces must be treated according Sika's Clear Aktivator or All Black installation process. Further information on the application and use of Pre-treatments, can be found in the corresponding Product Data Sheet. Windshields without ceramic coatings need proper UV protection.
Application
It is recommended to apply SikaTack® DRIVE (Purform®) with a powerful battery operated application gun.
Consider that the viscosity will increase at low temperature. For easy application, condition the adhesive at ambient temperature prior to use.
To ensure a uniform thickness of the bondline it is recommended to apply the adhesive in form of a triangular bead (see figure 1).

The open time is significantly shorter in hot and humid climate. The glass must always be installed within the open time. Never install a glass after the adhesive has built a skin.
Removal
Uncured SikaTack® DRIVE (Purform®) may be removed from tools and equipment with Sika® Remover-208 or another suitable solvent.Once cured, the material can only be removed mechanically.
Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.
Do not use solvents on skin.
