FAQs
What is the primary application for Teroson MS 939 BK?
It is primarily used as an industrial elastomer bonding adhesive for applications requiring high strength, good elasticity, and fast skin formation across various manufacturing sectors.
Is this adhesive suitable for outdoor use?
Yes, its ability to meet the damp heat test for the solar industry suggests good resistance to environmental factors suitable for outdoor applications.
What is the shelf life of Teroson MS 939 BK?
Refer to the product's technical data sheet or packaging for the exact shelf life and recommended storage conditions. Typically, unopened cartridges stored correctly have a defined shelf life.
Can this adhesive be painted over?
Compatibility with paint systems should be verified. Many MS polymer adhesives can be painted over after curing, but it's best to consult the technical data sheet or perform a test.
What are the temperature limits for application?
The application temperature range is usually specified in the technical data sheet. Generally, application should occur within a moderate temperature range, with curing influenced by ambient temperature and humidity.
How should I clean up uncured adhesive?
Uncured adhesive can typically be removed with a suitable solvent or cleaning agent specified by Teroson. Ensure proper ventilation and safety precautions are taken during cleanup.
Does Teroson MS 939 BK require a primer?
While it adheres well to many surfaces, priming might be recommended or necessary for certain challenging substrates or to achieve optimal long-term adhesion and performance. Consult the technical data sheet for specific guidance.
Troubleshooting
Adhesive not dispensing properly
Ensure the cartridge is correctly loaded into the dispensing gun and that the nozzle is properly opened or cut to the desired bead size. Check for any blockages in the nozzle.
Poor adhesion to substrate
Verify that surfaces are thoroughly cleaned and degreased. Re-evaluate surface preparation steps and ensure compatibility with the substrate material. Consider applying a primer if recommended for specific materials.
Slow curing time
Ensure application and curing conditions are within the recommended temperature and humidity ranges specified in the technical data sheet. Higher humidity generally aids curing, while lower temperatures slow it down.
Excessive adhesive bleed or squeeze-out
Adjust the bead size applied and ensure parts are properly aligned and clamped during assembly to control squeeze-out. Wipe away excess immediately after application, before skin formation, using appropriate cleaning agents.
