Elastomeric materials are typically supplied in the form of paste, cartridge, or putty. This is because these materials need to be malleable and able to conform to various shapes and surfaces in order to be effective as a sealant or adhesive.

Similarly, liquid forms of elastomeric materials would not have the necessary consistency to properly seal or bond materials.
