FAQs
Can this sealant be painted over?
Yes, once the sealant has fully cured, it is generally compatible with most standard industrial and automotive paint systems.
Is this product suitable for underwater use?
While it is moisture resistant, it is not designed for permanent immersion in water or high-pressure submerged conditions.
Does the sealant shrink after drying?
The Starchem PU Adhesive Sealant is formulated to have minimal shrinkage, maintaining a tight, consistent seal over time.
How do I remove uncured sealant?
Uncured material can be wiped away using a suitable solvent or an industrial cleaning wipe before it begins to harden.
Can it be used on plastics?
It adheres well to many plastics, but it is recommended to perform a small adhesion test on an inconspicuous area before full application.
Troubleshooting
Sealant is difficult to dispense from the cartridge
Ensure the nozzle is cut at an appropriate angle and verify that the sealant gun is functioning correctly; cold ambient temperatures can also make the sealant thicker.
Sealant failing to stick to the surface
Check that the surface is completely free of contaminants, oil, or dust; re-clean with a suitable solvent if necessary.
Sealant taking too long to cure
Curing time is dependent on temperature and humidity. Increase ventilation in the work area or raise the ambient temperature slightly to speed up the process.

Setup, Compatibility & Care
To prepare for application, ensure that all surfaces are completely clean, dry, and free of grease, oil, or loose debris. Use a standard 310ml manual or pneumatic sealant gun to dispense the adhesive. After cutting the nozzle to your desired bead width, apply the sealant in a continuous motion. Once applied, smooth the bead with a tool or a gloved finger dipped in a mild detergent solution to ensure full contact with the edges. Store unused cartridges in a cool, dry place with the nozzle sealed to prevent premature curing. Always follow the curing time recommendations provided on the cartridge before exposing the bond to heavy loads or moisture.
