Triazine is a nitrogen-containing heterocyclic compound with a six-membered ring structure consisting of three carbon atoms and three nitrogen atoms. It is a highly stable and versatile compound with a wide range of applications including UV absorber polymer additives, polymers, coatings, textile and dye flame retardants, healthcare and pharmaceuticals, automotive, agricultural films, herbicides and water treatment.


Triazines are widely used as UV absorbers in polymers such as plastics, resins and coatings. They offer significant advantages over other UVA absorbers such as benzophenone (BZP) and benzotriazole (BZT). A number of UVA absorbers for complex molded products, fibers, plain and corrugated sheets, bilayers, films, injection molded or co-extruded semi-finished parts give polycarbonate and polyester higher weathering resistance than the addition of conventional benzotriazole UVA absorbers.


Triazines are used as monomers in the synthesis of new polymers with desired properties such as thermal stability, electrical conductivity and mechanical strength.

Triazine is the best UV absorber. It helps protect coatings by absorbing sunlight rather than allowing it to reach adhesives, plastics, coatings and elastomers. It can be used to protect adhesives, plastics, coatings and elastomers from the damaging effects of outdoor weathering.

Triazine compounds are used to produce a range of dyes, including reactive, acid and direct dyes. Triazines are used as UV absorbers in textile auxiliaries and in polycarbonates, injection molding, thermoplastics, fibers, textiles and carpets to enhance durability, color fastness and performance. Can be used in industrial and automotive paints where thermal stability and durability are required.

Triazines are used as flame retardants in a range of materials including plastics, textiles and building materials.

Triazine derivatives are widely used in the healthcare and personal care industries. Triazine derivatives are used as UV absorbers in sunscreens. s-Triazine has been extensively studied for its wide range of applications in biological systems as an antibacterial, antiviral, anticancer and antifungal agent.

Automotive / Electronics IndustryAUTOMOTIVE / ELECTRONICINDUSTRY:
In the automotive industry, hydroxyphenyl homotriazine (HPT)-based ultraviolet absorbers (UVA) meet higher performance and quality requirements as well as cost pressures, however benzotriazoles (BTZ) often fail to meet or exhibit poor performance.

Triazines are used as light stabilizers (UV absorbers) for various polymers. Used in high performance agricultural PE films with high pesticide resistance.

Triazines are widely used as herbicides for their ability to prevent the growth of weeds. Atrazine, one of the most commonly used herbicides, is a triazine derivative.

Triazines have been used in water treatment applications as disinfectants and stabilizers for chlorine-based disinfectants.
UV absorbers are used in all synthetic materials, such as plastics made from polycarbonate (PC), polyester, polyamide (PA), polyethylene (PE), polyethylene terephthalate (PET), and others.

Why are triazines superior to benzotriazoles and benzophenones?

There are several factors to consider when comparing triazines to benzotriazoles and benzophenones. Here are some potential reasons why triazines may be considered superior to benzotriazoles:

Environmental impact: Triazines are generally considered to be less persistent and less toxic to aquatic organisms than benzotriazoles.

Regulations: Triazines are more tightly regulated than benzotriazoles, meaning that their use is subject to more scrutiny and restrictions to ensure that they are used responsibly and safely.

Availability: Triazines are used in a wider range of applications than benzotriazoles, making them a more readily available and cost-effective option.

Efficacy: Triazines have been shown to be effective in a range of applications such as herbicides, pharmaceuticals and water treatment, and can provide significant benefits in terms of increased crop yields, development of new treatments for diseases, and improved safety and quality of drinking water.

Persistence: Compared to benzophenone and benzotriazole, triazines have a shorter half-life in soil, meaning they break down more quickly and are less likely to persist in the environment.

Mobility: Triazines are less mobile in soil than benzophenone and benzotriazole. This means they are less likely to leach into groundwater and contaminate water sources.

Toxicity: Although triazines, benzophenones and benzotriazoles all have negative impacts on the environment, they are generally considered to be less toxic to aquatic organisms than benzophenones and benzotriazoles.

Performance excellence: In addition to the above mentioned triazines (hydroxyphenyltriazines, HPT), it outperforms benzophenone and benzotriazole as a UVA absorber polymer additive. It has a high thermal degradation temperature, making it stable during high temperature processing. It does not migrate or leach.

Triazine UV absorbers have excellent performance. In addition, the amount added to the polymer is usually low compared to other UV absorbers.

In automotive coatings, UV absorbers (UVA) based on hydroxyphenylpyrimidotriazines (HPT) are able to meet higher performance and quality requirements as well as cost pressures, whereas benzotriazoles (BTZ) often do not meet or exhibit poor performance.

Studies have shown that HPT has a very low vapor pressure and the best photostability (reducing its own loss during exposure), followed by BTZ (hydroxyphenyl benzotriazole) and BP (hydroxybenzophenone), and lastly, oxalanilide.

In addition to light persistence, heat resistance (i.e., low volatility)/thermal stability is a key point.

HPT also exhibits excellent chemical resistance and does not interact with metals or strong bases.

Triazines have very high thermal stability.

Triazines exhibit the best performance in terms of light retention and color retention, followed by benzotriazoles, benzophenones and oxalanilides.
