SikaTack® ULTIMATE
Primerless auto glass polyurethane adhesive
SikaTack® ULTIMATE is a cold-applied, fast curing, high-viscosity polyurethane adhesive designed for use in replacing direct glazed automotive glass parts. SikaTack® ULTIMATE does not require the use of a Sika® Aktivator or Sika® Primer pre-treatment product on glass or ceramic frit. When used as directed SikaTack® ULTIMATE is an appropriate adhesive for use in auto glass replacement applications.
- No pre-treatment required for glass or frit
- 30 minute Minimum Drive Away Time (MDAT)
- Crash tested according to FMVSS 212
AGR's Future is Now - SikaTack® ULTIMATE
30-minute MDAT and primerless auto glass adhesion is finally here.
The world of auto glass replacement will never be the same.
Innovation | Simplicity | Safety The Ultimate has been achieved.
ULTIMATE Used by Tech Olympics Winners
Two Sika product users recently took 1st and 2nd place in the Auto Glass Technician Olympics at this year's Auto Glass Week conference.
We congratulate both men on their wins (and prizes)!
Sika AGR Team Featured on IGA Podcast
Sika's Western Region Sales Manager, Mark OBrion, and Senior Product Engineer, Mike Rea, recently joined host Gary Hart on the Independent Glass Association's podcast. Key topics include primerless adhesive technology and how it's revolutionizing the auto glass industry, what's next in AGR, and a look at the future of automotive adhesion.

CURE MECHANISM
SikaTack® ULTIMATE 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. More information can be found in the Minimum Drive Away Time table that follows.
| Relative Humidity | Temperature (°C) | |||
| > -18 (0) | > 0 (32) | > 10 (50) | 20 – 49 (68-120) | |
| > 90 % | 30 | 30 | 30 | 30 |
| > 70 % | 30 | 30 | 30 | 30 |
| > 40 % | 30 | 30 | 30 | 30 |
| > 20 % | 30 | 30 | 30 | 30 |
| > 0 % | 30 | 30 | 30 | 30 |

CHEMICAL RESISTANCE
SikaTack® ULTIMATE 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 prepared with an Automotive grade glass cleaner. SikaTack® ULTIMATE is capable to bond on glass and ceramic frits without additional pre-treatment. Further information on the application and use of cleaning agent, can be found in the corresponding Product Data Sheet.
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
It is recommended to apply SikaTack® ULTIMATE 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 the form of a triangular bead (see figure 1).
Figure 1: Recommended bead configuration
Removal
Uncured SikaTack® ULTIMATE 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 or 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 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 climates. Never install any glass part after the product has built a skin.
