  • JS910 is compatible with all types of manual and robotic dispensing equipment currently available.
  • JS910, after mixing, must be homogeneous.
  • Part A is sensitive to water, hence we recommend to minimize water vapour penetration and adjusted cleaning.
  • After Application, there should be no air entrapped between JS910 and the primary sealant.
  • Make sure there are no air bubbles in the corners.
  • Glass must be perfectly clean, with no traces of detergent or any other pollution.
  • Spacers must be clean, dry and free from any other matter.
  • Recommended Application temperature 10-30°C
  • After Application, JS910 reacts with moisture. The curing speed is influenced by the humidity level in the surrounding air and the temperature.
  • For equipment cleaning, refer to the recommendations of the machinery manufacturer.
