The Indasa Polyurethane Silicone Sealer Bond is a professional-grade adhesive solution ideal for automotive, marine, and construction professionals or DIY enthusiasts who need a heavy-duty, high-strength bond. Its primary benefit is the combination of extreme bonding strength with permanent flexibility, allowing it to move with substrates without cracking; however, users should be aware that it is a permanent adhesive, making it difficult to remove once fully cured.

Yes, unlike silicone-based products, this polyurethane sealant is compatible with most automotive paint systems.
While it is water-resistant and excellent for sealing against leaks, it is not intended for continuous, permanent immersion in water.
Excess sealant can be wiped away using a clean cloth dampened with a suitable solvent, such as isopropyl alcohol or a specialized adhesive remover.
On most clean, non-porous surfaces, it adheres directly. However, for difficult plastics or specialized metals, a light sanding or adhesion promoter may be required.
This is a structural adhesive that remains paintable and offers significantly higher bond strength than standard silicone.
Ensure the nozzle is cut wide enough and that the internal foil seal at the base of the nozzle has been fully punctured.
High humidity is required for proper curing; if the environment is very dry, the cure time will extend significantly.
Check that the surface was thoroughly degreased and sanded to provide a mechanical key for the adhesive.
To use this 310ml cartridge, load it into a standard caulking gun and cut the nozzle to your desired bead width. Surfaces must be clean, dry, and free of contaminants to ensure a secure bond. Once applied, the sealant will begin to skin over within 15-30 minutes; it is recommended to apply steady pressure and allow at least 24 hours for a full cure, depending on the thickness of the bead and environmental humidity. Always store the cartridge in a cool, dry place and replace the cap tightly to prevent premature curing inside the nozzle.
