BASF Antioxidants: Guardian of the coatings industry

In the coating industry, antioxidants are like an unknown hero, silently protecting the performance and life of the product. In this field, BASF antioxidants stand out with their excellent quality and wide application, becoming the first choice for many companies. This article will start from the basic principles of antioxidants and deeply explore the application and unique advantages of BASF antioxidants in the coating industry, and combine specific product parameters and domestic and foreign literature to comprehensively analyze how it provides lasting protection for paints.

1. Basic knowledge of antioxidants: Why do you need it?

(One) Hazards of Oxidation Reaction

In coating formulations, resins, solvents and other components may undergo oxidation reactions due to the external environment (such as oxygen, ultraviolet rays, etc.), causing the coating to age, discolor or even crack. This phenomenon not only affects aesthetics, but may also weaken the protective function of the coating, thereby shortening its service life. Therefore, in order to delay these adverse changes, antioxidants emerged.

(II) Mechanism of action of antioxidants

Antioxidants mainly work in the following two ways:

1. Free Radical Capture: Inhibit free radical chain reaction and prevent the molecular structure from being destroyed.
2. Peroxide Decomposition: Convert the generated peroxide into a stable compound to reduce damage to the material.

Simply put, antioxidants are like a firewall that blocks the spread of "fire" (i.e., oxidation reaction) around, ensuring that the coating system is always in a stable state.

2. Analysis of the advantages of BASF antioxidants

As one of the world's leading chemical companies, BASF has accumulated rich experience in the research and development of antioxidants. Its product series covers a variety of application scenarios, especially in the field of coatings. Here are the core advantages of BASF antioxidants:

(I) Efficiency

BASF antioxidants can achieve significant antioxidant effects at extremely low additions, thanks to their advanced molecular design and high purity raw materials. For example, its celebrity products Irgafos® 168 and Irganox® 1076 are usually used in coatings at a concentration of only a few thousandths, but they can effectively extend the weather resistance and service life of the coating.

(II) Compatibility

BASF antioxidants are well compatible and can easily be incorporated into various types of coating systems, including water-based, oil-based and powder coatings. They can maintain excellent dispersion and stability whether under high temperature baking or room temperature drying.

(III) Environmental protection

As the global focus on environmental protection is increasing, BASF has actively developed green solutions and launched a series of environmentally friendly antioxidants that meet international standards. For example, some products have been REACH certified to ensure that their impact on human health and ecological environment is reduced.

(IV) Customized Service

BASF not only provides standardized products, but also personalized customization according to customer needs. For example, for high-performance coatings for outdoor use, specific combinations of antioxidant formulations can be recommended to further enhance their UV resistance and weather resistance.

3. Examples of application of BASF antioxidants in the coating industry

(I) Building exterior wall coating

Building exterior wall coatings are often exposed to sunlight, rainwater and air pollution, so they require extremely high anti-oxidation performance. BASF antioxidants are particularly outstanding in this field. For example, after adding an appropriate amount of Irganox® 1010 and Irgafos® 168 to a well-known brand of acrylic exterior paint, the coating's light retention rate was increased by 30%, and there was no obvious fading or powdering in actual tests for up to 5 years.

(II) Automotive Repair Paint

Auto repair paint needs to be fast curing, high gloss and long-term durability. BASF provides optimized antioxidant solutions for such applications, such as Irganox® L109. This product not only accelerates the drying speed of the coating, but also effectively prevents hot yellowing, making the repaired body look brand new.

(III) Industrial anticorrosion coatings

BASF antioxidants are also indispensable for anticorrosion coatings in harsh environments such as marine engineering and oil pipelines. By working in concert with other additives, they can help the coating resist salt spray erosion and mechanical wear, greatly extending the maintenance cycle of the equipment.

IV. Detailed explanation of the technical parameters of BASF antioxidants

In order to understand the characteristics of BASF antioxidants more intuitively, we have compiled the technical parameter lists of the following popular products:

It should be noted that the specific dosage should be adjusted according to the type of paint and the conditions of use, It is recommended to conduct small tests under laboratory conditions before entering large-scale production.

5. Domestic and foreign literature support and case studies

(I) Progress in foreign research

In recent years, European and American scholars have achieved a series of important results in the research of BASF antioxidants. For example, a study from the University of Michigan showed that when Irganox® 1076 and Irgafos® 168 were combined in a certain proportion, the UV resistance of polyurethane coatings can be significantly improved. Experimental data show that after 300 hours of artificial accelerated aging test, the tensile strength of the coating decreased by only 5%, much lower than that of the control group without antioxidants (down 25%).

(II) Domestic application cases

In the Chinese market, BASF antioxidants have also been widely used. A large coating manufacturer introduced Irganox® 245 during its new product development process, specifically for anticorrosion coatings for offshore wind towers. The results show that after two years of continuous operation under simulated sea breeze environment, the coating still maintains good adhesion and integrity, which has been highly praised by customers.

VI. Summary and Outlook

BASF antioxidants occupy an important position in the coatings industry due to their high efficiency, compatibility and environmental protection. Whether it is civil buildings, transportation or industrial facilities, they can provide lasting protection for all types of coatings, helping customers achieve higher economic benefits and social value.

In the future, with the continuous emergence of new materials and technologies, BASF will continue to increase its R&D investment and launch more innovative products. At the same time, we also look forward to seeing BASF antioxidants show greater potential in emerging fields (such as new energy, smart buildings, etc.) and create a better living environment for mankind.

After, borrow a classic slogan to describe BASF antioxidant: "You may not see it, but it is always guarding."
