Application Note
1. Clean surface to make it clean, dry, free of oil or grease.
2. Apply the Comensflex Activator or Comensflex Primer on the surface.

4. The suggested work temperature is 5-35°C, the best work temperature is 15-25°C.
Property of the Sealant Layer
1. The product cures with the moisture in the air, which forms a high strength elastic structural sealant layer.
2. The sealant layer is resistant to water, weak acid, neutral cleaner which do not contain chlor-alkali. It can shortly resistant to fuel, oil, fat, and crude oil. But it should be avoided strong acid, lye, bleach and other organic solvent.

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.
