Evonik Launches AEROSIL® 200: Nano-Scale Rheology Control Innovation for Global Coatings and Adhesives Industries

Evonik Launches AEROSIL® 200: Nano-Scale Rheology Control Innovation for Global Coatings and Adhesives Industries

 

April 4, 2025, Essen, Germany – Evonik, a global leader in specialty chemicals, today announced that its flagship product AEROSIL® 200 has become a core additive in the global coatings, adhesives, and composites industries, thanks to its exceptional nano-scale rheology control performance. This hydrophilic fumed silica (CAS No.: 112945-52-5) offers a high purity (SiO₂ content >99.8%), nano-sized particle structure (average particle size ~12 nm), and specific surface area of 175-225 m²/g, providing comprehensive solutions from anti-settling to thixotropic control in industrial production.

 

I. Technical Breakthrough: From Lab to Industrial Application

 

Produced via flame hydrolysis (fumed process), AEROSIL® 200 forms a unique three-dimensional network structure, enabling rapid establishment of stable thixotropic properties in waterborne, solvent-borne, and radiation-curing systems. Key advantages include:

 

- Versatility: Compatible with one-component/two-component coatings, powder coatings, and adhesives without additional modification.

- Efficiency: Only 1.0-2.0% addition (based on total formulation) significantly improves anti-sagging and anti-settling performance, reducing batch quality fluctuations caused by pigment agglomeration.

- Sustainability: Compliant with EU REACH, U.S. FDA, and China GB 30981-2020 regulations, supporting low-VOC coating formulations.

II. Market Insight: Core Driver for Global Coatings Industry Growth

 

According to Markets and Markets, the global coatings market is projected to grow from $194.5 billion in 2024 to $227.5 billion in 2029, with a CAGR of 3.2%. AEROSIL® 200 excels in the following sectors:

 

1. Industrial Coatings: Enhances adhesion and salt spray resistance in automotive primers and marine anti-corrosion coatings, extending service life.

2. Wood Coatings: Improves film uniformity and prevents sagging during vertical surface application, meeting stringent requirements of high-end furniture manufacturers.

3. Powder Coatings: Optimizes powder flowability and prevents caking, supporting high-speed spraying processes for precision components like new energy vehicle battery housings.

4. Adhesives & Sealants: Strengthens anti-sagging and anti-cracking properties in electronic encapsulants and construction sealants, adapting to complex working conditions.

 

III. Sustainability: Evonik’s Global布局 and Green Commitment

 

Evonik achieves localized production of AEROSIL® 200 through its Zhenjiang joint venture plant (co-established with Xinan Chemical), leveraging by-products from silicone monomer production to create high-value products while recycling by-product hydrochloric acid for "zero discharge" goals. Additionally, AEROSIL® 200 supports the development of waterborne and powder coatings, helping customers comply with EU’s Directive 2004/42/EC on VOC emissions.

 

Industry Trends:

 

- Environmental Friendliness: The global green coatings market is expected to reach ¥4.238 trillion by 2027, with AEROSIL® 200’s superior performance in waterborne systems driving growth.

- Functionalization: Expanding applications in emerging fields like 5G adhesives and lithium battery separator coatings.

 

IV. Technical Support and Customer Value

 

Evonik’s global technical team provides full-cycle services from formulation optimization to process design:

 

- Dispersion Recommendations: High-speed stirring (>1500 rpm) or pre-dispersion in solvents/resins is recommended for uniform nanoparticle distribution.

- Compliance Support: Offers pharmaceutical-grade (IPEC-GMP) and food-grade (E551) certifications for sensitive industries like pharmaceuticals and cosmetics.

- Custom Solutions: Available in hydrophobic modified grades (e.g., AEROSIL® R972) or high-specific-surface-area grades (e.g., AEROSIL® 300).
