Potassium sulfate speeds up the setting and hardening of the gypsum plaster, reducing the drying time and improving the strength and durability of the drywall. Potassium sulfate also acts as a fire retardant, as it releases water vapor when exposed to high temperatures, slowing down the combustion process. Potassium sulfate is a safe and effective additive that can enhance the performance and quality of various
drywall products.
