1. Basic components of cabinet powder coatings
Cabinet powder coatings are mainly composed of five major components: resin, curing agent, pigment, filler and additives. These components each play an important role in the coating and jointly determine the performance and quality of the coating.
Resin
Resin is the main film-forming substance of cabinet powder coatings and a key component in the coating formula. It provides the basic properties of the coating, such as adhesion, hardness, flexibility, weather resistance, etc. Common types of resins include polyester resins, epoxy resins and polyurethane resins. These resins have different performance characteristics and can be selected according to factors such as the material, design requirements and use environment of the cabinet.
Curing agent
Curing agent is another important component in cabinet powder coatings. It reacts chemically with the resin to cure the coating into a film at high temperature. The type and amount of curing agent have a great influence on the performance of the coating. Choosing a suitable curing agent can improve the hardness, wear resistance and chemical resistance of the coating. At the same time, the use of curing agent can also shorten the curing time of the coating and improve production efficiency.
Pigment
Pigment is an important component that gives cabinet powder coatings color. It determines the color and hiding power of the coating. The selection of pigments should be based on the decorative requirements and color matching of the cabinets. High-quality pigments have good dispersibility and stability, which can ensure that the coating is brightly colored and lasting.
Filler
Filler is an auxiliary component in cabinet powder coatings. It is mainly used to increase the thickness and hardness of the coating and improve the wear resistance and scratch resistance of the coating. Common fillers include calcium carbonate, barium sulfate, talcum powder, etc. The type and amount of fillers should be adjusted according to the formulation requirements and performance requirements of the coating.
Additives
Additives are functional ingredients in cabinet powder coatings. They are mainly used to improve the construction performance and coating performance of the coating. Common additives include leveling agents, degassing agents, brighteners, antistatic agents, etc. These additives can reduce the viscosity of the coating, improve the fluidity and wettability of the coating; at the same time, they can also eliminate bubbles and pinholes in the coating, and improve the flatness and gloss of the coating.
2. Performance characteristics of cabinet powder coatings
Cabinet powder coatings have a variety of performance characteristics, which make it widely used in cabinet painting.
Environmental protection
Cabinet powder coating is a solvent-free coating. It does not contain organic solvents and volatile organic compounds (VOCs), so no harmful gas emissions will be generated during use. This meets the requirements of modern home decoration for environmental protection performance.
High efficiency
Cabinet powder coating has high coating efficiency. It can be applied by processes such as electrostatic spraying or fluidized bed dipping, and the required coating thickness and appearance effect can be achieved in one coating. This greatly improves production efficiency and reduces coating costs.
Durability
Cabinet powder coating has good durability and weather resistance. It can resist the erosion of harsh environments such as ultraviolet rays, moisture, acid and alkali, and keep the coating bright in color and long-lasting in gloss. This makes the cabinet less susceptible to damage and aging during use.
Decorativeness
Cabinet powder coating has a rich selection of colors and textures. It can be customized and produced according to the customer's decoration requirements and color matching to meet personalized needs. At the same time, the coating surface is flat and smooth, with high gloss, and has a good decorative effect.
