A New Protective Option for the Wood Preservative Industry -- KATHON
kathon preservative, with the chemical name being a mixture of methyl chloroisothiazolinone and methyl isothiazolinone, is a broad-spectrum and highly effective bactericide. It is widely used in industrial circulating water, coatings, adhesives, papermaking, and metal processing fluids, etc. Its main function lies in inhibiting the growth of microorganisms, preventing equipment corrosion, product deterioration, and system efficiency decline caused by the proliferation of bacteria and fungi. In the industrial structure of Dalian, which is dominated by sheet materials, chemicals, and textiles, Kathon preservative effectively solved the microbial contamination problems caused by humid environments and organic matter accumulation in the production process, significantly extending the equipment lifespan and ensuring the stability of product quality.
This product exhibits excellent water solubility and thermal stability, maintaining its activity within a wide pH range (2–9), and has good compatibility with most industrial additives. Its mechanism of action is to penetrate the microbial cell wall and interfere with the enzyme system function, achieving the dual effects of rapid sterilization and long-lasting inhibition. Compared to traditional formaldehyde-based or bromine-based preservatives, carbazon preservatives have a lower usage concentration and a faster onset time, while having a lower environmental load and conforming to the current trend of green chemical engineering. In the adhesive production lines of some large-sized board enterprises in Linyi, the application of carbazon has extended the product shelf life by more than 30% and significantly reduced the frequency of system cleaning.
Dalian Tianwei has a production workshop that complies with GMP standards and a complete quality control system. It adopts a continuous synthesis process to ensure the batch stability and purity of the products. Its R&D team focuses on the optimization of preservatives' combinations and the research of environmentally friendly alternatives. They have developed dedicated formulas suitable for complex conditions such as high salt and high temperature. The technical services cover multiple industrial clusters in Liaoning and its surrounding areas. The factory has obtained ISO14001 environmental management system certification, demonstrating its practical achievements in sustainable production.
