In its uncured state, silicone rubber is a highly adhesive gel or liquid. To convert it to a solid, it must be cured, vulcanized, or catalyzed.This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
Silicone components (A+B) must be mixed accurately by weight (scale required) or else they do not work. Tin-catalyst silicone shrinks somewhat and does not have a long shelf life. Acetoxysilane-based RTV releases acetic acid during the curing process. The locally released acetic acid can attack solder joints, detaching solder from copper wire.
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Blu Tack was originally white, but following fears that children could mistake it for chewing gum, a blue colouring was added. [2] In the United Kingdom in March 2008, 20,000 numbered packs of pink Blu Tack were made available, to help raise money for Breast Cancer Campaign, [4] with 10 pence from each pack going to the charity.

For example, to see "stygian blue": staring at bright yellow causes a dark blue afterimage, then on looking at black, the blue is seen as blue against the black, also as dark as the black. The color is not possible to achieve through normal vision, because the lack of incident light (in the black) prevents saturation of the blue/yellow ...
