- This change is prompting many customers, laboratories, manufacturers and organisations that use Honeywell products to ask the following questions: Which company is Solstice? Does Honeywell Advanced Materials still operate? Have the former Honeywell products changed? To which company do HYDRANAL™, Genetron®, Solstice® and the specialty chemicals products now belong?
- The answer is: Solstice Advanced Materials is the company that inherits Honeywell's former Advanced Materials business, with a technology base, product portfolio and expertise built up over many decades within the Honeywell ecosystem.
1. How did Honeywell Advanced Materials become Solstice?
- Honeywell is a large US industrial technology group operating in many fields such as aerospace, automation and advanced materials.
- In its strategy to restructure its business portfolio, Honeywell decided to separate the Advanced Materials division into an independent company.
- In October 2024, Honeywell announced the plan to separate Advanced Materials. By 25/03/2025, Honeywell announced that the official name of the new company is Solstice Advanced Materials. The separation was completed on 30/10/2025.
- From this point on: Honeywell Advanced Materials → Solstice Advanced Materials
- Solstice has become an independent company, publicly listed in the United States under the ticker SOLS on Nasdaq.
- This means that if customers were previously familiar with the name Honeywell Advanced Materials, then nowadays when searching for information about this advanced materials business, they will increasingly encounter the brand Solstice Advanced Materials.
2. Is Solstice Advanced Materials a completely new company?
- Not completely. This is a very important point to understand.
- Solstice Advanced Materials is a new company in terms of legal personality and ownership structure, but the business operations of the company have a foundation inherited from Honeywell's Advanced Materials.
- According to Solstice, the new company was formed from the separation of Honeywell's Advanced Materials division and continues to inherit the technology base, research capabilities, products and experience in the field of specialty materials.
- Solstice states that the history of this business goes even deeper, spanning many stages of development of the chemical and materials industry, before it became part of Honeywell after the merger of AlliedSignal and Honeywell in 1999.
- Therefore, it can be understood simply: Solstice Advanced Materials is the independent company that was separated from Honeywell Advanced Materials, and not a completely new brand starting from zero.
3. What products does Solstice Advanced Materials currently sell?
After the separation from Honeywell, Solstice focuses on the field of specialty materials – materials and specialty chemicals.
Solstice's product portfolio currently includes several important technology groups such as:
- Refrigerants and next-generation cooling agents
- Electronic materials and semiconductor materials
- High purity chemicals
- High performance fibres
- Pharmaceutical packaging materials
- Specialty chemicals and materials for many industries
- Chemicals and reference standards for laboratory analysis
Solstice currently serves more than 3,000 customers worldwide and focuses on applications with high demands on material technology.
4. Which well known product brands now belong to Solstice?
This part is particularly important for companies that are using Honeywell products.
Some notable brands in Solstice's portfolio include:
HYDRANAL™ – Karl Fischer chemicals and reference standards
- HYDRANAL™ is one of the most famous brands in the field of determining water content by the Karl Fischer method.
- The HYDRANAL™ portfolio includes Karl Fischer reagents, water standards and reference materials for water content determination.
- Solstice currently continues to supply the HYDRANAL™ portfolio to the analytical chemicals market and laboratories.
- This is particularly noteworthy for:
- QC laboratories
- R&D departments
- Chemistry testing laboratories
- Pharmaceutical plants
- Food plants
- Chemical plants
- Research laboratories
- If a company previously searched for Honeywell HYDRANAL™, customers may now start to see the products introduced under the Solstice Advanced Materials system.
5. Solstice® Refrigerants – One of the most outstanding product lines
- Another important area that Solstice continues to develop is next generation refrigerants.
- The Solstice® refrigerants products are developed to respond to the trend of reducing the use of agents with a high GWP – Global Warming Potential.
- For example, Solstice currently offers refrigerant lines such as:
- Solstice® 454B – R-454B
- Solstice® L40X – R-455A
- Solstice® 454C – R-454C
- Solstice® ze – R-1234ze
- Among them, Solstice 454B is presented as an alternative to R-410A with a GWP of 466, approximately 78% lower than R-410A according to the manufacturer's technical information.
- Solstice's refrigerant solutions are applied in:
- Air conditioning
- Commercial refrigeration
- Cold storage
- Supermarkets
- Chiller
- Industrial cooling
- Data centres
- In particular, when the demand for AI and Data Center grows rapidly, the demand for efficient cooling technologies also becomes an important development direction of Solstice.
6. Why are there still products on the market bearing the Honeywell name?
- This is a question that many customers may encounter during the brand transition period.
- The separation of Honeywell Advanced Materials into Solstice does not mean that all products were renamed on the same day.
- According to Solstice, after the corporate separation process, the company has transitional brand licensing agreements with Honeywell for certain product lines.
- Therefore, during the transition period, customers may encounter:
Honeywell + product name
or
Solstice + product name
depending on each product line, market and stage of the transition. Solstice states that products will gradually be transferred to the Solstice brand when the new brand building process is implemented.
- Therefore, the continued appearance of products bearing the Honeywell name on the market does not mean that Solstice is not the successor of the Advanced Materials business.
7. What is the difference between Honeywell and Solstice Advanced Materials now?
- After the spin-off transaction was completed, Honeywell and Solstice Advanced Materials are two independent companies.
- It can be imagined simply:
- Solstice confirms that the former websites of Advanced Materials and Honeywell Research Chemicals have been moved to solstice.com and lab.solstice.com.
8. Special attention for laboratories using Honeywell products
- For laboratories, QC and R&D, this transition can make it more difficult to search for products on the Internet.
- For example, previously customers could search for:
Honeywell Hydranal
Honeywell Karl Fischer
Honeywell Research Chemicals
Honeywell Advanced Materials
- In the coming time, the corresponding keywords may gradually move to:
Solstice Hydranal
Solstice Karl Fischer
Solstice Research Chemicals
Solstice Advanced Materials
- Solstice now operates its own research chemicals portal at lab.solstice.com, while transferring user accounts from the Honeywell Research Chemicals system to the new system.
- This is very significant when a company searches for:
- Analytical chemicals
- Reference standards
- Karl Fischer reagent
- HYDRANAL™
- Certified Reference Material
- Water standard
- Research chemicals
9. Solstice Advanced Materials – A new brand but inheriting the Honeywell foundation
- From a market perspective, the emergence of Solstice Advanced Materials can be seen as an important transition.
- Honeywell Advanced Materials has become an independent company named Solstice Advanced Materials, but the technology base and experience of this business have been built up over many decades.
- Solstice currently positions itself as a company specialising in specialty materials, focusing on areas with high requirements for technology and with long-term growth trends.
These can be mentioned:
- Cooling – HVAC – Data Center → demand for efficient cooling technologies and low GWP refrigerants.
- Semiconductors – Electronics → demand for materials with high purity and high accuracy.
- Healthcare → packaging materials that help protect pharmaceuticals.
- Laboratory & Analytical Chemistry → chemicals and reference standards, including the HYDRANAL™ brand.
- Industrial Materials → specialty materials serving many industrial sectors.
10. Honeywell Advanced Materials → Solstice: Summary of the points to remember
The transition can be summarised in 5 points:
1. Honeywell did not change its name to Solstice. Solstice is the company that was separated from Honeywell Advanced Materials.
2. Solstice Advanced Materials has officially operated independently since 30/10/2025.
3. Solstice is listed on Nasdaq with the ticker SOLS.
4. Many technologies and well known product brands from Honeywell Advanced Materials continue to be developed by Solstice, including Solstice® refrigerants, HYDRANAL™, Spectra® and Aclar®.
5. During the transition period, some products may still appear with the Honeywell name due to the brand licensing agreements, before fully moving to the Solstice brand case by case.
Conclusion
- Honeywell Advanced Materials has now become Solstice Advanced Materials – an independent company specialising in specialty materials and chemicals.
- This change is not simply a change of logo or brand name. It is the result of the spin-off process carried out by Honeywell in order to turn the Advanced Materials division into an independent company with its own strategy and development orientation.
- For customers using the former products of Honeywell Advanced Materials, recognising the Solstice Advanced Materials brand will become increasingly important.
- Especially for products such as HYDRANAL™, analytical chemicals, Karl Fischer reference standards, Solstice® refrigerants and specialty materials, customers may start to encounter product information, technical documents and the ordering system under the Solstice brand instead of Honeywell Advanced Materials.
- Solstice Advanced Materials – a new brand, a technology foundation inherited from Honeywell Advanced Materials, oriented towards the next generation of specialty materials and advanced science solutions.
