Dow Corning 789 Weatherproofing Silicon Sealent,300 ML,Black

Nice

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.

I used this in my 4feetx1feetx1.5feet aquarium to reseal after removing the old silicone on the inside edges. Although this seems to be a little bit softer than clear/white silicone, adheres well to the glass . Allowed it to cure for a week and started using the aquarium.Observations:Soft and smooth while applyingSticks well to the glassWatertightFishes are fine, its been a week. just stating this as some silicone are toxic to fish (Especially antifungal)Looks neatNote: Due to its soft and flexible nature may not be suitable for very large aquariums without a frame.Just my thought, i could be wrong.My tank has an outside frame with strong black silicone from the company.

Short life supplied item became unusable very quick as it solidifiedKindly ensure FIFO not LIFO of any lifed item suppliedDiscarded short life must not be shipped as it being disrepute to both supplier and Amazon brand

Good product , don't think about this product just buy it.

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).

The media could not be loaded. 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.

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.
