CURE MECHANISM
SikaTack® ASAP+ cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the reaction proceeds more slowly. More information can be found in the Minimum Drive Away Time table that follows.

CHEMICAL RESISTANCE
SikaTack® ASAP+ 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, sound, dry and free from all traces of traditional and non-traditional contamination. All corrosion must be removed and all bare metal scrapes and scratches must be prepared in accordance with Sika's Corrosion Treatment recommendations. For preparation of all bonding surfaces it is required to read and understand the instructions given in the Sika AGR Technician Training Manual. Windshields without ceramic coating need proper UV protection.
Application
Place cartridge or unipack in a Sika approved oven for a minimum of 1 hour. Product can be heated for a total of 10 hours (either consecutively or in shorter periods adding up to a total of 10 hours).
Cut off the tip of the nozzle in accordance with the vehicle manufacturer’s recommendations and screw onto the cartridge or the unipack adapter.
It is recommended to apply the adhesive with a piston-type application gun. To ensure a uniform thickness of adhesive bead, we recommend that the adhesive be applied in the form of a triangular bead (see fig. 1).

Removal
Uncured SikaTack® ASAP+ may be removed from tools and equipment with Sika® Remover-208 or another suitable solvent, such as mineral spirits. Once cured, the material can only be removed mechanically.
Hands and exposed skin have to be washed immediately using a suitable industrial hand cleaner and water.
Do not use solvents on skin.
Application Limits
- Avoid contact with alcohol and alcohol containing solvents during cure.
- Do not apply on frozen surfaces, through standing water, or on wet surfaces.
- Do not apply over silicones or in the presence of curing silicones.
- Glass parts must always be installed within the open time. The open time is significantly shorter in hot and humid climate as well as in temperatures below 40°F. Never install any glass part after the product has built a skin.
- Always use in conjunction with Sika® Aktivator PRO, Sika® Primer-207, or Sika® Primer-207 AGR.
