2021-11-01   Pageview:70

1, Slightly yellow transparent solution, PH<5.0, stable at pH 2-14.

2, Anti-algae: Anti-algae performance, can effectively kill algae and inhibit the growth of algae.

3, Stable: not easy to decompose, good compatibility with emulsion paint and additives, even dispersion, does not affect the performance of water-based emulsion paint.

4, Environmental protection: that is, high safety, no harm to human health, no harmful effects on the environment.

5, Strong anti-mold power, with less drug dose can kill or inhibit the reproduction and growth of mold.

6, Non-oxidizing fungicidal preservative, good compatibility with emulsions under the conditions of use concentration, formaldehyde free, VOC free, environmental friendly, miscible with water, low molecular alcohol, simple operation.

7, Broad-spectrum: that is, to kill or inhibit a variety of mold, with a wide antibacterial spectrum. Can effectively kill anaerobic bacteria, Legionella, hydrogen sulfide generating bacteria, rust bacteria, Bacillus, Escherichia coli, Pseudomonas, red yeast, Aspergillus niger, Rhizopus niger, Sporotrichum, Aspergillus oryzae, Staphylococcus aureus and other bacteria, fungi, yeasts, molds, kill mollusks and plankton, sterilization and anti-mold and algae effect broad spectrum and long-lasting, does not produce resistance.

 

 

 

 

 

 

 

 

 

 

 

 

The more commonly used method is to add colored pigments to the coating formulations. Due to the strong light absorption of the pigments, they can effectively shield ultraviolet light, such as carbon black and phthalocyanine blue. The anti-photoaging mechanism of pigments is not only limited to light shielding, sasol wax aqua 30 but also has deeper complex effects. Pigment coloring in light-curing coatings will hinder the light absorption efficiency of photoinitiators and seriously interfere with light curing efficiency and film performance. In addition, pigment coloring will also make the coating absorb more light energy, increase the temperature of the coating, and generate heat. The possibility of aging degradation increases. Therefore, the use of pigment-colored rice to improve the light stability of the coating has certain applications in traditional thermosetting coatings, but it does not meet the actual requirements in light-curing coatings.

The anti-photoaging method commonly used in the plastics, rubber, and coating industries is to add ultraviolet light absorbers, free radical traps, excited state quenchers and hydrogen peroxide decomposers. These four types of light stabilizers have their own different The function plays a role in the different stages of polymer photoaging, inhibits the polymer photoaging process, and plays a pivotal role in the field of polymer materials anti-photoaging.

UV absorber
Various light stabilizers have different light stabilization mechanisms. The protection mechanism of ultraviolet absorbers is based on absorbing harmful ultraviolet radiation and dissipating energy in the form of heat without causing photosensitization. In addition to having sufficient light absorption capacity, UVA should also have high light stability. Otherwise, it will quickly be consumed in unstable secondary reactions. The biggest drawback of UVA light stabilizers is that the stabilized sample has a relatively high thickness, so that UVA can obtain a sufficiently high absorbance to achieve the purpose of light stabilization. Therefore, if UVA is used alone for thin-layer samples, it is difficult to obtain the ideal light stabilization effect, and it is often used in combination with other types of light stabilizers.
