Final answer:
The accelerator paste used in the polysulfide rubber composition contains chemicals that promote the vulcanization process, such as accelerators, sulfur, and activators.
Step-by-step explanation:
Polysulfide rubber, also known as mercaptan rubber, is a type of rubber that is commonly used in sealants and adhesives due to its excellent resistance to chemicals, fuels, and UV radiation.
The accelerator paste used in the composition of polysulfide rubber typically contains a mixture of chemicals that promote the vulcanization process.
These chemicals can include accelerators such as zinc oxide or magnesium oxide, sulfur, and activators like stearic acid or mercaptobenzothiazole.
The accelerator paste helps to speed up the vulcanization process, allowing for the crosslinking of polymer chains and the formation of a more durable material.
