Main Products:

Introduct: Our factory was established in 1986 and produced China's first high-temperature bolt anti-seize agent—Model GF-1, ending the long-term reliance on imported "bolt protective agents" for high-temperature industrial equipment. After a year of user trials and sampling inspections by research departments, it passed the quality appraisal by the Hebei Provincial Science and Technology Commission and the Cangzhou Bureau of Standards and Metrology in December 1987. By 1991, we successively developed Models GR-9 and GR-12 anti-seize agents, creating a product series and expanding applications from petrochemicals, chemical fibers, thermal power, chemical engineering, and fertilizers to railway locomotives and metallurgical systems. In 2006, we further developed and produced 767 high-purity silver-based high-temperature anti-seize agents and Cu-a copper-based anti-seize agents, with product quality comparable to imported alternatives. In 2009, we began producing metal heat treatment protective agents. Our company has been rated as a "Trustworthy Quality Product" by the Cangzhou Bureau of Technical Supervision for five consecutive years and is a key protected enterprise in Dongguang County. The factory currently has fixed assets of 500,000 yuan and 116 employees (including 2 senior engineers and 4 engineers), with a dedicated technology development department responsible for new product development, technology transfer, and solving challenges in user production processes.
