By adding short-cut fiberglass material to nylon, excellent strength and toughness can be achieved. The composite material composed of this combination exhibits non-toxicity, lightweight, excellent mechanical strength, wear resistance, and good corrosion resistance.
In recent years, it has been widely used in various fields such as military, construction, shipbuilding, electrical tools, machinery industry, sports equipment, office equipment, and automobiles.
Some customers from Deco Chemical, during the application process, need to apply paint on these types of plastics to obtain better adhesion, typically using aluminum paste powder coating. However, adhesion issues often arise on these plastic parts.
In order to support our customers’ development applications, the DCA Additive Application Center has conducted some experiments specifically targeting the adhesion of aluminum powder coating on these plastic components, providing them as a reference.
