Can I accelerate the curing process of Dow Corning sealants...791, 795, 790, etc?

According the specialists at Dow Corning, the cure rate for one part silicone products depends on the humidity in the air, the silicone bead thickness that is applied, and to a lesser degree, heat. Increasing the RH (relative humidity) surrounding the silicone or reducing the thickness of the material applied will help reduce the time it takes to cure the material. Increasing heat (not over 140F or 60C) is actually a less effective method. Cure rates for two part silicone products, however, are mainly affected by heat and to a smaller extent, humidity.

It’s like the feeling after you wash your entire car. Personally, I tend to drive the car differently afterward as if it’s brand new again. Silly but true. Maintaining clean and clear windows on your vehicle is important for good visibility. Now, look how clean and crisp your field of vision looks. Years ago, practically the only window cleaner available was the blue stuff.
