preface
In the coating industry, driers play a key role in accelerating the oxidation, polymerization, cross-linking and drying of paint films. Especially in oil-based paints, these film-forming substances often contain unsaturated double bonds, which harden and solidify the paint film through oxidation reactions and cross-linking processes. Traditional driers mainly use organic acid soaps such as cobalt, manganese, lead, zinc, calcium, etc. However, they face problems such as dark color and toxicity, which prompts the coating industry to continuously seek the research and development of new driers.
The role of driers in the coating industry
Problems with traditional driers
Traditional organic acid soap driers perform well in promoting oxidation reactions, but they also bring some problems. Among them, the paint film may be darker in color, expensive, and even toxic. These problems have created a demand for more environmentally friendly and efficient driers, and have promoted the coating industry's urgent exploration of new driers.
Progress in rare earth driers
In recent years, the coating industry has introduced rare earth driers while solving the problems of traditional driers. These new driers have achieved certain success in improving color and reducing toxicity, but they have not yet completely replaced expensive rare earth cobalt driers.
The rise of a new generation of driers
Facing the problems of traditional driers, the coatings industry urgently needs a new drier that can completely replace cobalt driers. Scientists and engineers have made unremitting efforts to help develop a new generation of driers.
Sustainability and environmental friendliness
This new generation of driers is designed with sustainability and environmental performance in mind. Reducing the impact on the environment and reducing the use of harmful substances is one of the directions for innovation in the coating industry.
color control
In the process of searching for alternatives, special attention was paid to the impact of new driers on the color of the paint film. The goal is to achieve a clearer, brighter paint film and improve the aesthetics of the paint.
Cost-effectiveness
As an important cost in coating production, a new generation of driers needs to provide efficient performance while having a more economical production cost to promote its widespread application.
The development trend of driers in the future
Intelligent and customized design
With the development of technology, future driers are expected to achieve intelligent and customized design, providing more accurate performance matching according to the needs of different coating application fields.
Multifunctional drier
The new generation of driers may not only achieve the function of drying, but also provide coatings with multiple properties such as antibacterial, wear resistance, and weather resistance to meet the market's increasing demand for coating performance.
Bio-based drier
As the demand for eco-friendly products increases, the development of bio-based driers will become an important direction in the future to reduce the negative impact of chemical synthesis on the environment.
Conclusion
As the innovation engine of the coatings industry, driers continue to evolve to meet market and environmental demands. The development of a new generation of driers will drive the coatings industry toward a more sustainable, efficient and environmentally friendly future. In this process, the efforts of scientists and engineers will provide more convenient and diversified coating products for our lives and work, bringing a new chapter to the coatings industry.
