Protecting structural steel and wood from the devastating effects of fire is paramount in modern construction. Intumescent coatings offer an effective solution, and at their core lies the powerful performance of Ammonium Polyphosphate (APP II). NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality APP II, a key ingredient for superior intumescent coating formulations for steel and wood.


Intumescent coatings work by expanding significantly when exposed to high temperatures, forming a thick, insulating char layer. This char acts as a barrier, delaying the temperature rise of the substrate and extending its structural integrity during a fire. APP II, particularly its Phase II form, is highly valued for its high thermal stability and ability to initiate this crucial intumescent reaction effectively.


Our APP II, a phosphorus and nitrogen-based flame retardant, plays a dual role in this mechanism. It acts as an acid source, catalyzing the dehydration of poly-alcohols within the coating, leading to the formation of char. Simultaneously, it releases non-flammable gases that contribute to the expansion of the char and dilute flammable gases, thus enhancing fire protection.


For professionals seeking an reliable intumescent coating for steel structures supplier, NINGBO INNO PHARMCHEM CO.,LTD. ensures consistent quality and performance. Our APP II is characterized by its fine particle size and low water solubility, which are crucial properties for stable and effective coating formulations, suitable for both water-based and solvent-based systems.


The benefits of using NINGBO INNO PHARMCHEM CO.,LTD.'s APP II extend beyond fire resistance. It is a halogen-free solution, aligning with growing environmental regulations and ensuring a safer application and end-use environment. This makes it an ideal choice for green building initiatives and projects prioritizing ecological responsibility.


Understanding the APP II for wood fireproofing price and its overall value demonstrates the cost-effectiveness of this high-performance material. NINGBO INNO PHARMCHEM CO.,LTD. is committed to partnering with formulators and manufacturers to develop next-generation intumescent coatings, providing the essential raw materials to meet and exceed fire safety requirements for various building materials.
