About this product
A glazing adhesive with a very short clock: 10 minutes to skin, 8 minutes open time. The sheet says the glass must always be installed inside the open time, which makes it a two-person job.
Using this specific product
Sika SikaTack PRO is listed here as the Windshield bonding adhesive version for windshield replacement, glass bonding, and vehicle glazing. For bonding parts, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Windshield bonding adhesive; related versions can use different timing.
- For windshield replacement, glass bonding, and vehicle glazing, pay particular attention to surface fit, cleanliness, clamping pressure and bond-line thickness.
- At 23°C (73°F) and 50% relative humidity.
How to check readiness
Test a noncritical offcut or wait for the stated load milestone before stressing the joint. The data sheet gives an open time of 8 minutes; the glass must be installed within it. The data sheet gives a skin time of 10 minutes.
Avoid this mistake
Handling strength and full load strength are different milestones.
