This product should be added at the end of the production process and stirred thoroughly to ensure uniform distribution. For example, to inhibit the growth of mold in non-food area latex-based wallpaper adhesives, add 0.5% (5 lbs) per 1000 lbs of latex-based adhesive formulation.
In order to better protect the marine environment, scientists from various countries are trying to find a truly non-toxic antifouling agent that does not kill sea creatures, but has repellency and hinders their growth. European, American, and Japanese researchers extract natural products from marine organisms and screen effective antifouling agents, such as terpenes, alkynes, polycyclic compounds, steroids, and isothiocyanate pp wax korea from sponges, corals, and algae Chemical structure characterization and biological activity test of active substances such as acid salts are expected to obtain more effective low-toxic and non-toxic antifouling agents. This field is very popular, some results have been achieved, and a large number of papers are published every year, but there is still a long period of time for such antifouling agents to enter the practical application.
Generally speaking, marine antifouling agents are developing towards the direction of low toxicity, non-toxicity, high efficiency, broad spectrum, economy and convenience.
Preservatives, anti-fungal agents and anti-algae agents
Microorganisms include tens of millions of bacteria and molds, and they are ubiquitous on the earth. But their survival and reproduction also depend on environmental conditions: organic matter, oxygen, humidity, pH and temperature.
Of course, for microorganisms, like all living organisms, the most fundamental need is water. They can exist with water, but at what speed they will reproduce depends on whether there are nutrients needed for their reproduction in the water. As far as water-based paint is concerned, the presence of water is abundant. First of all, it uses water as a solvent or water as a dispersion medium. Secondly, the coating film of water-based paint is hydrophilic to a certain extent. Moreover, there are nutrients required by microorganisms in water-based paints and their coating films, especially water-based paints thickened with cellulose. This determines that there is a serious problem of dealing with microorganisms in the formulation design, production and application of water-based coatings.
