Solstice Website and Portal Updates

Solstice Advanced Materials is a pure-play specialty materials company with leading market positions in refrigerants, semiconductor materials, industrial-grade fibers and healthcare packaging solutions. It was formed by the spin-off of Honeywell’s Advanced Materials business into an independent, U.S. publicly traded company on October 30, 2025.

The previous advancedmaterials.com and lab.honeywell.com portals have become solstice.com and lab.solstice.com, respectively. Customers can conveniently access either portal via a single sign-on.

How do I access my user account?

Users should log in through the ‘Sign In’ link in the website header.

Note, user accounts that were registered on the Honeywell Advanced Materials or Honeywell Research Chemicals websites have moved to solstice.com and lab.solstice.com, respectively.

To access an existing account for the first time after the move, users will need to reset their passwords. This is a simple, one-time process that they will complete the first time they log in to the new website(s).

• Select the Sign In’ link in the website header
• Select ‘Sign in to My Portal.’ (On the Research Chemical portal, click the ‘Sign In’ button on the drop-down menu.)
• Enter the email associated with the account
• Click ‘Forgot my password’
• Follow the link we send to the email box to set up a new password

If you are registered on both websites, you only need to reset your password on one of them. You can use the same password to access either site, making the login process more convenient.

If you require assistance, please reach out to AMDigitalSupport@solstice.com.

How do I register for a Solstice account or for the Research Chemicals portals?

You can quickly and easily create an account by clicking the ‘Sign in’ button on either site.

• On the Solstice website, visit ‘Create an Account’. (On the Research Chemical portal, select ‘Register’.)
• Enter the required registration information.
• Review your entries and click ‘Create account.’
