• Construction Gypsum-board, Plasterboard and Drywall Retarders

Boric Acid

• Boric Acid is a mineral that can be used as a retarder additive in gypsum products. Not only does it help to slow down the setting time of the gypsum and improve its workability, but it also provides strength-enhancing properties to the plasterboard for durability. Boric Acid can be an effective fire retardant and help improve the fire resistance of the drywall panel or plasterboard.

  • Board strength: Boric Acid has been shown to positively affect the stability of drywall panels and gypsum plasterboard. It acts as a cross-linking agent, which helps to form stronger bonds between the gypsum particles in the board. This results in a commission less likely to break or crack under stress.
  • Fire resistance: Boric Acid is an effective fire retardant commonly used to manufacture fire-resistant building materials. When added to drywall panels and gypsum plasterboard, it helps to reduce the spread of flames in the event of a fire.
  • The setting of the board: Boric Acid can also help control the gypsum material’s setting time during manufacturing. This allows for better control over the consistency and strength of the final product. In addition, Boric Acid can also improve the workability of gypsum-based material during manufacturing. It can act as a lubricant, making it easier to form the material into the desired shape and size.
