Special effect pigments in powder coatings

Since powder coatings have no volatile organic compounds (VOC) emissions, and the characteristics of high performance and durable. They are more widely used in Europe, America and Asia-Pacific markets. Powder coating can be applied in the finishes of high light, low light, plain light and metallic, and the color is not restricted. Special effect pigments can create a unique, dazzling visual effects for powder coating. In fact, they are suitable for all resin systems. Many of them can also be used in outdoor durable coatings and industrial coatings.

Special effect pigment has following three advantages: a. this pigment can creat optical shades unpredictable illusion, for example, pearl pigment applied to car paint can observe this phenomenon; b. this pigment can produced to elusive of with angle different color attract eye of surprised color effect, for example, it can be used in car paint or decorative sex printing; c. this pigment can simulate natural pearl effect and applied to buttons, plastic bottles and many other decorative objects. Effect pigments in the automotive paint are mainly aluminium powder, Pearl powder, nano-titanium dioxide and graphite powder.

Because the composition of the powder coating is a 100% solid with little or no waste, so it is efficient. It does not require a solvent system. If necessary, spray booth can be built in a relatively small space. And the transmission and curing equipment can be switched with each other, liquid paint system can be easily replaced by powder coating system. Replacement of liquid transfer systems require cost, but this can quickly recoup their investment by increasing efficiency.

The biggest market of effect pigment is in architectural coatings include aluminum building sheet and curtain wall panels. Gray metallic is the most commonly used in the field of color. This color can be available in conjunction with black or gray powder paint with topical white Pearlescent pigments. MICA effect pigment is cheaper and more durable alternatives in Aluminum powder pigment. Metallic pigment needs to cover a layer of varnish to increase durability and reduce gloss. However MICA effect pigment does not need to cover a layer of varnish. Because it is chemically inert.

Effect pigments can be mixed use with transparent coloring agent to get different colors. Powder coatings one of the fastest growing top-coat paint in coatings industry. With the increase of amount of powder coatings, effect pigments also increases. Researchers are constantly working to develop new products to improve powder coating technology.Click here to get more!
