Intumescent coatings represent a cutting-edge approach to passive fire protection, particularly for structural steel, wood, and concrete. Unlike traditional fire-resistant materials that merely insulate, intumescent coatings react to heat by swelling to form a thick, insulating char layer. At the heart of this transformative technology often lies ammonium polyphosphate (APP).


The effectiveness of an intumescent coating manufacturer largely depends on the quality of their active ingredients. APP acts as the acid source in these systems. Upon heating, it decomposes to produce phosphoric acid, which then catalyzes the dehydration of carbon-based polyols (like pentaerythritol) within the coating. This process forms a stable, voluminous char that insulates the substrate from extreme temperatures, significantly extending its fire resistance time.


For critical applications like steel structure fireproofing, the choice of components within the fire protection coatings APP formulation is paramount. Our Mflam AP110L, an advanced ammonium polyphosphate solution, provides the robust performance required for these demanding environments. It is designed to be highly compatible with various binders and synergists, allowing formulators to create coatings that achieve optimal intumescent properties and adherence.


NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated supplier of high-grade ammonium polyphosphate, essential for the production of top-tier intumescent coatings. Our commitment to consistent quality ensures that manufacturers can confidently develop products that meet the most stringent fire safety regulations worldwide. The ability to effectively protect load-bearing structures for extended periods during a fire is invaluable, safeguarding lives and assets.


Beyond structural steel, intumescent coating technology with APP is also vital for cables, pipes, and other critical infrastructure. The low smoke density and favorable environmental profile of APP make it a preferred choice over halogenated alternatives.
