Application
Surtek 3668 is used for windshield direct glazing. It is widely used for structural bonding and
installation for windscreen of car, bus, train, boat, etc.
Application Note
1. Use Comensflex Activator to make the substrate surface clean, dry, free of dust or grease.
2. Shake Comensflex Primer bottle to make the material even before using it. Use brush to apply the primer onto the cleaned surface for a thin layer.
3. Apply the sealant after the primer dried. Install the glass before the sealant tack free. The best working temperature is 20-30°C, humidity 50-70%.
4. The sealant cures with moisture in the air. The lower the temperature and humidity is, the slower the curing is; and the higher the temperature and humidity is, the faster the curing is. Too high temperature and humidity may cause bubble in the cured sealant.
5. Avoid the adhesive sealant from alcohol, acid, ammonia chemicals. These chemicals will cause the adhesive sealant uncured.

Storage and Shelf Life
When stored at the recommended conditions in original, unopened
containers, this product has a shelf life of 9 months (cartridge),6 months (sausage and drum).
The shelf life of polyurethane sealant is related to the temperature and humidity of the environment. The recommended storage temperature is 5-25° C, humidity is <50% RH. It is strictly prohibited that the transportation or storage temperature is over 30°C or the humidity is over 80% RH. And high-temperature container transportation is prohibited as well. In the long-time high temperature and high humidity storage environment, the product is easy to get viscous,extrusion will be deteriorated and shelf life will be shortened.
