Pearlescent finish

Nacreous pigment n. Translucent pigment which, when added to transparent coating material, creates a deep lustrous and pearlescent finish. Kirk-Othmer encyclopedia of chemical technology pigments-powders. John Wiley and Sons, New York, 1996. 

Colorability is another reason IDs select plastics for many products. Molding color into a product eliminates finishing and painting operations, thus reducing costs. Beyond cost, integral color also masks the nicks, chips and scratches that impair appearance during the life of the product. Color effects are almost limitless. Transparent, translucent, pearlescent, fluorescent, or marbleized colors are readily available for use in plastics. 

Pearlescent pigments give rise to a white pearl effect often accompanied by a coloured iridescence. The most important pearlescent pigments consist of thin platelets of mica coated with titanium dioxide which partly reflect and partly transmit incident light. Simultaneous reflection from many layers of oriented platelets creates the sense of depth which is characteristic of pearlescent lustre and, where the particles are of an appropriate thickness, colours are produced by interference phenomena. Pearlescent pigments are used in automotive finishes, plastics and cosmetics. 

Later, the uses for transparent sheet included rules and set-squares for geometrical drawing, while pearlescent materials were highly effective for show purposes—as in drum kits for dance bands, accordions, and other musical instruments. Some pearl finishes were produced much as veneers, for embellishing small items like the handles of pen-knives. 

Metallic pigments. Metallic pigments are used on the surfaces for luster and brilliance finishes that are normally not produced by conventional pigments. For many applications, a metallic effect is highly desirable and can be achieved by adding aluminum, zinc, bronze, stainless steel, or pearlescent pigments. 

The colors found in industry today can be grouped into four main categories of finishes solid or straight shade colors, metallic colors, pearlescent colors and special effect colors. Any...

Vehicle refinish (VR) coatings are used to repair damaged or corroded car paint systems. They must exhibit the same performance characteristics as the original paint system if they are to meet the car manufacturer s bodywork corrosion warranty. However, the most important feature of VR coatings is their colour. There are approximately 150 million cars on the roads of Europe, painted in over 20000 different colours, and every year a further 600 new colours are added. Paints also age and, depending on climatic conditions, a 10-year-old car may have changed colour considerably. A VR bodyshop must be able to match the colour of the car, irrespective of its age, colour and type of finish (which will usually be either a solid colour, metallic, or pearlescent). This is achieved by the skills of the VR bodyshop and the colour-matching system of the paint manufacturer.
