In what form(s) are elastomeric materials supplied?

  1. Powder

  2. Liquid

  3. Paste, cartridge, putty

  4. Tablet

The correct answer is: Paste, cartridge, putty

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. Powder and tablet forms, while they may contain the same ingredients, would not be suitable for these purposes. Similarly, liquid forms of elastomeric materials would not have the necessary consistency to properly seal or bond materials.
