Sikaflex 295 UV
Recently we trialed several windscreen installations using Sikaflex 295 UV and here is what we found.
Now just for the record, any reviews you read on the Windscreen Blog are unbiased and not advertisements. We don’t do “cash for comments”. Any products we recommend on the Blog are because we feel there are benefits to using them. However, Sika did provide us with several sausages of 295 UV for us to trial free of charge.

Sikaflex 295 UV is a product specifically designed to be used as a gap filler. Sika boasts that it has superior UV protective properties and is ideally suited to filling in large gaps that you find on Buses, Coaches and other larger windscreens. It also does well in marine environments.
We tested 295 UV on several Stryker Fire Service Vehicles. Service 8® recently had to reglaze the fire service fleet at the Air Services Australia Brisbane workshop, as all vehicles were being refurbished. Many of the windows were almost falling out as the adhesive had deteriorated after many years of sitting idle in the hot Australian Sun.
We have completed several already, however, we were not completely happy with the product we were using, Sika Drive. Drive has a very fast cure time and starts to skin in only a few minutes. This becomes a problem when filling and smoothing gaps to a professional finish. If the product begins to cure/skin before you have smoothed the gaps, the end result is compromised and can look very sloppy. This especially becomes a problem on larger windscreens were multiple sausages of sealer must be pumped in a short amount of time.
To solve this problem try Sika 295 UV. The benefits are self evident when you use it. It pumps very quickly as it is a softer viscosity. However, we still prefer to use a cordless sealer gun for more control/speed.
The work time (Tac Free Time) is 60 minutes compared to Sika Drive which is 15 minutes. This gives you allot of time to work with the product. So even if you are not the most skilled of technicians and need a second chance to get that professional finish, then 295 UV will allow you to do this.
Sikaflex 295 UV is designed to weather extremely well in harsh sunlight and marine environments. It also boasts that the shrinkage is 1% (estimated), so it should work very well for bus, coach and machinery that have large gaps to fill with adhesive. It has a shelf life of 12 months, which is a bonus if you only use small volumes.
As technicians we tend to get set in our ways regarding the adhesive products we use. One product for all applications seems to be the order of the day. This is usually the case if you work for someone else, often the price takes priority.
So for gap filling, Sika 295 UV get the thumbs up from Service 8®. It really is a fantastic product which will improve the finish and longevity of your work. It is certainly a product we will be using for gapfiller applications in the future.
At the time of this writing local auto glass supply outlets did not stock this item on the shelf, it was only ordered on request. However, we got our samples direct from the Brisbane Sika Warehouse who stock just about every Sika product. Best speak to your local Sika rep for availability details.
