Potassium neodecanoate, as an efficient and environmentally friendly catalyst, plays a vital role in the production process of spray-coated rigid foam. This special organometallic salt, through its unique chemical properties, not only accelerates the formation process of polyurethane (PU) and polyisocyanurate (PIR) foams, but also improves foam quality, reduces costs and promotes sustainability It has shown significant advantages in development. The following is an in-depth look at the use of potassium neodecanoate in spray rigid foam applications.
Overview of spray hard foam process
Spray rigid foam is a processing technology that sprays liquid polyurethane or polyisocyanurate mixture directly onto the surface of an object, and then quickly foams and solidifies. This technology is widely used in many fields such as building insulation, refrigeration equipment, and vehicle manufacturing. It is favored by the industry because it can provide a continuous and seamless thermal insulation layer, and its construction is flexible and convenient.
The mechanism of action of potassium neodecanoate
Potassium neodecanoate, chemically named Potassium neodecanoate, is a carboxylate chain carboxylate among anionic surfactants. In the foaming formula of spray hard foam, it mainly functions as a trimerization catalyst, promoting the reaction between isocyanate (-NCO) and hydroxyl (-OH) or water, especially catalyzing the formation of a cyclic trimer structure, which is beneficial to improving the The mechanical properties and thermal stability of rigid foam are crucial. The alkaline nature of potassium neodecanoate ensures efficient reaction, and its good compatibility enables it to be evenly distributed in the foam system to ensure a uniform foam structure.
Advantages of use
- Efficient catalytic performance: Potassium neodecanoate can significantly accelerate the foaming reaction rate, shorten the curing time, and improve production efficiency, which is particularly important for large-scale industrial production.
- Improve foam quality: By optimizing the microstructure of the foam, potassium neodecanoate helps form a fine and uniform cell structure, thereby enhancing the mechanical strength, thermal insulation performance and dimensional stability of the hard foam .
- Environmental protection attributes: Compared with traditional catalysts containing heavy metals, the low toxicity characteristics of potassium neodecanoate are in line with the current pursuit of green chemicals and help reduce environmental pollution during the production process. Comply with environmental protection regulations.
- Post-curing effect: Potassium neodecanoate can not only accelerate the initial curing, but also promote the later “curing” process, that is, the continued optimization of the foam after curing, further improving the performance of the product .
- Formulation adaptability: It is suitable for a variety of rigid foam systems, including spray rigid foam, PIR rigid foam and general PU rigid foam, showing good formula compatibility and application flexibility.
