Fusion Bonded Epoxy Coating

Fusion Bonded Epoxy coating is a type of coating composed of Fusion Bonded Epoxy and a curing agent, forming a robust, wear-resistant, and corrosion-resistant protective layer when applied to the surface of an object. This coating often exhibits high strength, excellent adhesion, and chemical stability, making it widely used in various fields to provide protection and enhance aesthetics to coated objects. Fusion Bonded Epoxy powder coating is a dry powder coating mainly consisting of Fusion Bonded Epoxy. It is applied to the surface of objects through processes such as electrostatic spraying or electrophoretic coating, forming a strong, durable, and corrosion-resistant protective layer.

Composition and Preparation

Fusion Bonded Epoxy: The primary component is Fusion Bonded Epoxy, a material known for its excellent chemical resistance, strength, and adhesion properties.

Curing Agent: Typically includes organic peroxides, used to crosslink Fusion Bonded Epoxy molecules during the coating curing process, forming a sturdy network structure.

Additives: Modifiers, leveling agents, and other additives may be added to adjust the coating's properties and application characteristics.

Preparation Process

Mixing: Fusion Bonded Epoxy, curing agent, and additives are uniformly mixed to form a homogeneous powder premixture.

Crushing: After cooling, the premixture undergoes crushing treatment to create a powder suitable for electrostatic spraying.

Coating: Powder particles are often coated to improve moisture resistance and flowability.

Application Processes

Electrostatic Spraying: One of the most common coating methods. Charged powder adheres uniformly to the surface of the coated object through the action of an electrode's electrostatic field.

Electrophoretic Coating: A process where a charged liquid powder suspension is immersed in an object with electrodes, and powder adheres to the object's surface through electrophoresis.

Baking and Curing

After coating, the object enters a baking chamber, where high-temperature baking melts and levels the powder coating. Simultaneously, Fusion Bonded Epoxy reacts with the curing agent, forming a robust crosslinked structure. The cured coating exhibits wear resistance, chemical corrosion resistance, and excellent physical properties.

Advantages of Fusion Bonded Epoxy Coating
