Liquifast 9100 Latest windscreen adhesive technology – no isocyanate training required

#Workshop

Whether it’s windscreens, side windows or rear windows – our Liquifast 9100 comes into play when maximum bonding power is required during repairs. The high-quality 1C PUR adhesive impresses with strong initial adhesion and can be processed without the hazardous substance training for isocyanates legally required for most PU adhesives – regardless of vehicle age. It also meets all current vehicle manufacturer specifications. This makes it ideal for workshops that rely on efficiency, safety and future-proof technology.

Ideal adhesive – even in stressful everyday workshop life

Our product stands for innovative adhesive technology: Thanks to its user-friendly formulation, it is immediately ready for use and extremely efficient due to short drive-away times. This saves resources and enables fast, safe processing even under everyday conditions in the workshop.

Liquifast 9100 is a state-of-the-art 1C PUR windscreen adhesive developed specifically for professional use in the automotive sector. Whether for cars, vans, commercial vehicles or special-purpose vehicles: thanks to its high initial adhesion (high tack), the windscreen remains stable in its installation position immediately after the specified drive-away time – an important quality feature. This is particularly advantageous with steep or heavy windscreens, as nothing can slip or sink anymore.

Safe for modern vehicles

Liquifast 9100 is also the right choice if antennas, heaters or assistance systems are installed in the windscreen. And this is now standard for many vehicles. This adhesive also offers full performance for modern bodies such as painted aluminum, magnesium and hybrid bodies with composite materials.

And if the window needs to be replaced again, residues of the Liquifast 9100 adhesive bead will not interfere with the adhesion. “This is the case for many other products on the market that do not require training and are based on MS or hybrid technology,” says David Kaiser, Head of the Research and Development Department at LIQUI MOLY.

Convenient to use

The following preparation steps are important for optimum bonding results:

Cleaning: The bonding surfaces must be free of oil, grease, dust and dirt. Ideal for this: our Windshield Cleaner Foam. Then clean the bonding area with our Cleaner and Thinner.
Priming: Before bonding, an adhesion promoter (“primer”) is applied – this ensures a strong and durable bond. Our Active Primer is suitable for this, which also has a diisocyanate content of less than 0.1% and is therefore training-free.
Observe drying time: After applying the primer, wait at least ten minutes (at standard climate 23°C/50 percent relative humidity) before applying the adhesive.
Tip: Our Liquifast 9100 bag set contains all the products required for professional use, except for the Windshield Cleaner Foam. For workshops, this means: Everything essential is at hand, no need to reorder. So repairs can be started directly in the event of vehicle damage – without losing any time.

Conclusion

If you need to rely on safety in application, tested functionality and high quality when installing windscreens, our Liquifast 9100 is the best choice. The 1C PUR window adhesive scores points in practice with high initial strength, short drive-away times and is ideally adapted to the requirements of modern vehicles.
