Commonly Used High Viscosity Polyurethane Adhesive Sealant for Structural Bonding

APPLICATION
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.
