Paint coating mold inhibitor
ince water-based coatings are mainly used in special environments such as winemaking, food, beverages, medicine, chemical industries, construction buildings, and underground structures. The main characteristics of these environments are high humidity, high temperature, abundant nutrients, and being highly conducive to mold growth. Therefore, solving the problem of mold prevention on the coating film of water-based coatings is even more crucial. According to the aforementioned basic principles and requirements for selecting an ideal coating film mold prevention agent, we have developed a kind of environmentally friendly coating film mold-killing and sterilizing agent 3Q-301 coating film anti-mold and disinfectant for water-based coatings. During the research process, effective utilization of microbial testing methods was made. Through special additives and appropriate processes, the originally hydrophobic active components were formed into a stable system dispersed in water. Additionally, the internal anti-corrosion agent and coating film mold prevention agent should be selected based on the usage environment of water-based coatings and their appropriate dosages should be designed. Firstly, the climatic conditions of the usage area should be considered. In hot and humid regions, various microorganisms multiply rapidly, so highly effective sterilizing agents should be used with a higher dosage; secondly, exterior wall coatings not only need to be affected by sunlight but also need to be eroded by wind and rain, and special consideration should also be given.
Due to the different mechanisms of action of various types of preservatives and fungicides, they have their own distinct antibacterial spectra. In some cases, the combined use of multiple preservatives and fungicides can achieve complementary and synergistic effects, which is more effective than using a single preservative or fungicide. It can also expand the broad-spectrum antibacterial property while reducing the usage concentration, thereby enhancing the safety of the product. Clearly, the compound preservative and fungicide will dominate the future coating anti-corrosion and anti-mold system. In today's era when green anti-corrosion and anti-mold have become favored by the majority of consumers, the research, development and application of compound and functional preservative and fungicide will have great prospects.
