Exploring the Outstanding Applications of Ultra-fine Dicyandiamide in Powder Coatings
Jan 06, 2025| Exploring the Outstanding Applications of Ultra-fine Dicyandiamide in Powder Coatings
1. Ultra-fine dicyandiamide can optimize the storage stability of powder coatings.
Due to its tiny particle size, ultra-fine dicyandiamide can be dispersed more stably in the system during the storage of powder coatings and is less likely to agglomerate or settle. This ensures that after long-term storage, the components of the powder coatings remain uniform, and there will be no differences in local curing effects caused by uneven distribution of dicyandiamide. Thus, it guarantees that the powder coatings taken at different times can achieve consistent performance after coating and curing.
The good compatibility of ultra-fine dicyandiamide with other additives and resins also helps maintain the chemical stability of the entire powder coating system, slows down the premature reactions or performance deterioration that may be caused by storage environment factors (such as temperature and humidity fluctuations), and extends the shelf life of powder coatings.
2. Ultra-fine dicyandiamide can facilitate the application of powder coatings in special fields. In some fields where extremely high electrical insulation performance of coatings is required, such as the coating of electronic components and electrical equipment, the coatings formed with the participation of ultra-fine dicyandiamide, by virtue of their highly cross-linked and compact structures, exhibit excellent electrical insulation performance, which can effectively prevent current leakage and ensure the safe and stable operation of the equipment.
For some outdoor facilities that require coatings with good weather resistance, such as bridges and building exteriors, in the powder coating process, the weather-resistant coatings formed with the help of ultra-fine dicyandiamide can effectively resist the long-term erosion of natural factors such as ultraviolet rays, rain, and wind-blown sand, reduce the phenomena of coating chalking and fading, and extend the maintenance cycle and service life of the facilities.
3. Ultra-fine dicyandiamide meets the requirements of new coating processes.
With the wide application of new coating processes such as electrostatic spraying and fluidized bed coating, higher requirements have been put forward for the performance of powder coatings. Due to its small particle size and good fluidity, ultra-fine dicyandiamide can better adapt to the requirements of these advanced coating processes. In electrostatic spraying, it can make the powder coatings adhere to the surface of workpieces more evenly and improve the powder application rate. In fluidized bed coating, it can enhance the contact and fusion effect between the powder coatings and preheated workpieces, ensuring uniform coating thickness and reliable quality.
