They have an especially short shelf life if in hot and humid conditions. Keeping them in the refrigerator will help extend their days, and keeping nozzles always attached will also help them cure slowly. Obviously, refrain from opening the tubes until you are ready to use them. Keep in mind that other people, and even pets, may come in contact with the space you are working in, so make sure your silicone applicator is safely away from children and animals.
Choose a work area that is well ventilated if your adhesive has an odor. Manufacturers always get queries from people asking if there is any miracle substance that can help remove the sealant. Well, the answer to this is no. The only way you will be able to remove sealant is through mechanical methods, such as a cheese wire or sharp knife, or by abrading it with a sander.
Before you purchase silicone adhesive or sealant for your project, you must check the materials you are working with. There are adhesives made especially for certain materials. Here is a guide to choosing the right silicone for your project.
For industrial applications like engines, oil pans, transmissions, etc. If you're looking for a general-purpose, durable sealant that can be used in a wide range of industrial applications, check out the Window Silicone Sealant.
I like that you explain how the level of humidity can affect the time it takes for the caulk to dry, such as how having more in the air shortens the process. It might help to consider the time and other factors before choosing a solution so you can figure out which one would be best to purchase.

Transparent silicone sealant is almost invisible, and therefore the scope of its use is extremely high. So, colorless sealant is used to seal the seams of wooden interior elements, to seal glass structures, to seal cracks in flooring, to fix elements for example, tiles to a concrete base. In this case, the aquarium sealant must be resistant to salt and fresh water, UV radiation, have low shrinkage and heat resistance, be absolutely harmless to fish and small animals not to give off carcinogens and unpleasant odor.
When choosing an aquarium sealant, you can pay attention to the transparent silicone SomaFix, which meets all of the above requests. Primary hardening time of this remedy is 20 minutes. Transparent silicone is well suited for gluing and sealing joints of an aquarium, terrarium and other glass, smooth surfaces.
So, for example, the Silirub AQ glue sealant becomes hard under the influence of moist air. The initial cure time is 7 minutes. The total drying time of the composition depends on the thickness of the sealing layer. So, on average, the silicone freezes at a speed of 1.
Most manufacturers give a recommended time on the sealant. If not they all have numbers for contact so things can be checked. We have had many customers call us back as they have not waited the given time and it then needs to be re sealed. On average it takes 24 hours to cure but every manufacturer is different. The best advice is to follow the instructions on the tube.
The make we use say 24 hours but if we are using them in areas highly exposed to water ie a shower cubicle then we recommend waiting at least 48 hours. It would be fine after 24 but we just want to be extra cautious. Well it all depends on which brand you use for the sealant. I would make sure you read the instructions on the tube as some will differ. But generally the sealant should be dry within 24 of application.
Don't risk it and use the bath before then or it could fail and cause a leak, which is the last thing you want. One of the biggest problems we see with sealants around baths is the repeated reapplication of additional sea lent on top of old sealant. In order to get the best from the sealant the surface of the walls need to be dry, dust and grease free.
