Clariant launched the next-generation, melamine-free flame retardant – Exolit AP 422 A – a safer solution that meets the demands of both performance and environmental concerns.

The new melamine-free flame retardant is suitable for applications including intumescent coatings, firestop sealing systems, and PIR insulation panels.

In 2023, melamine was classified as a Substance of Very High Concern (SVHC). To address current and future regulations around melamine, Clariant has been proactively working on this innovative solution for several years, developing an SVHC-free alternative to the existing melamine-containing Exolit AP 422 flame retardant.

Besides its melamine-free nature, the new Exolit AP 422 A provides superior fire resistance across multiple applications including intumescent coatings, firestop sealing systems, and PIR insulation panels.

Its non-halogenated nature also helps minimize hazardous emissions, providing safer usage in critical industries.

“Exolit AP 422 A responds to key market trends around tightening fire safety standards, environmental and health concerns, regulatory compliance needs, operational efficiency demands, and the need for versatile solutions across many applications,” said Christian Battenberg, Global Business Development Manager Polymer Solutions from Clariant.

Exolit AP 422 A has already been incorporated in some firestop products. Customers commented that the new melamine-free flame retardant provides reliable fire protection performance at the same time as aligning with sustainability commitments.
