Corning 789 Weatherproofing Silicon Sealent,300 ML,Black

I saw this silicone used for window sealing for high-rise buildings. I used it for my kitchen sealing, which is little way too much. Some pros and cons: - PROS: - 1. Perfect texture and easy to dispense. 2. Comes with nozzle. 3. Neutral curing, and hence no smell. 4. Excess can be wiped off with thinner. CONS: - 1. Black color, so not suitable for surfaces, which are visible. 2. Curing takes 6~7 days (entire layer).

Item well adhere to concrete. Make sure to clean all loose debris and dry before apply. I used on roof cracks and no water leaking in continuous rain. Received with nozzle.

This is a waterproof silicone sealant, its black in colour, the surface hardened after an hour after applying and it takes more than a week to cure internally. I personally used in aluminium and glass, therefore it worked perfectly there, it also sticks to wood , other metal and plastic, but its not paintable.

I bought 6 of those glue to build a 12 feet aquarium. Used the glue to fix the tank 6 days before and still the glue is sticky and not drying. I asked the experts and they say this type of glue can dry within 24 hrs and if they don’t dry then they will never dry because the glue is expired. Be careful while buying online. They sell the expired product because it is not returnable.
