MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202541007247 A) filed by Saint-Gobain Placo on January 29, 2025, for Termite-Repellent Gypsum Board With Integrated Termiticidal Mixture And Method Of Production.
Inventors include Deepti Yadav; Balakrishnan Sundaram; and Arun Thainana.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention relates to a termite-repellent gypsum board comprising a gypsum core, a paper or glass fiber facing, and a termiticidal mixture integrated within the gypsum core. The termiticidal mixture includes a termiticidal agent, such as bifenthrin, and a foaming agent in a ratio ranging from 1:1 to 1:5. This mixture imparts effective anti-termite properties to the board. The board is designed to provide long-lasting protection against termite infestations while maintaining the mechanical strength of the gypsum board, including improved core hardness and nail pull resistance. The invention also includes a method for producing the termite-repellent gypsum board, wherein the termiticidal mixture is incorporated into a gypsum slurry, which is then formed into the board and dried at temperatures between 70°C and 200°C. The method optimizes the physical properties of the board, such as pore size and strength, to enhance both termite resistance and structural integrity.
