Silicone Type
Specialized silicones, such as sealants able to tolerate high temperatures or expand when dispensed, have a more complicated chemical structure. As a result, the sealing time is slightly longer.
Silicone Purity
Some silicones are blended as acrylic caulk or elastomeric compounds, resulting in a modest delay in curing time.
Humidity
If you apply your new silicone caulk on a hot and humid day, it can help speed up the curing process of fresh caulk.
Temperature
The quicker silicone cures are often related to a moderate temperature. To speed up the curing process, it is recommended that you avoid applying direct heat to silicone, as when you blow hot air directly onto your silicone, it may shorten the life of your silicone caulking project.

You can also open the windows and turn on a fan to help the drying process.
What is drying silicone?
Drying is the initial, rapid process where moisture and water evaporate. Curing is much slower and refers to the chemical changes that take place after silicone gets exposed to oxygen. Your silicone will be a fully functional sealant if it's just dried – you don't necessarily need to wait for it to cure. ...
How to make silicone cure faster?
You can also use a blow dryer to really speed up the process. However, be sure to keep keep the blow dryer at a low or moderate temperature, and stay at least 1 ft (0.30 m) away from the adhesive when blow-drying it. If you use high heat, it could actually make the silicone take longer to cure.
How to get rid of sticky glue?
If the layer of adhesive is too thick, it will take more time to dry. By scraping off any additional adhesive, you allow the air to get to the adhesive and shorten the drying time. If you don’t have a putty knife, you can use a butter knife to get rid of the excess adhesive.
How to use catalyst on silicone?
To use the catalyst, squeeze out a dab of it from the tube and apply it directly to the silicone adhesive. The catalyst hardens the silicone by removing water from the compound and increasing the purity of the adhesive. You can use 2 dabs of the catalyst to speed up the drying process even more.
How long does adhesive last?
If the tube is out of date, the adhesive will take longer to dry. If the adhesive takes longer to dry than it says on the tube, this is most likely because it has gone past its shelf life. Sealants, however, are good for about 12 months. Many adhesives say they come with a lifetime guarantee.

Temperature and Silicone: What You Need to Know
Strong, durable, and versatile, silicone sealant is a favorite for professionals and amateurs alike. With its ability to cure quickly and hold for years, it is hard to find another product with the same sealing power of silicone.
Cold
Silicone sealant can be applied in temperatures as low as -29°C (-20°F), although the lower the temperature the longer the silicone will take to cure.
Side note: Moisture
The most damaging element to silicone sealant is not heat or cold, but moisture. Before applying a bead of sealant, one should be absolutely sure to dry the surface completely, as failing to do so will result in a weak seal.
