Minatec
The surface resistance which can be obtained using Minatec CM pigments lies in the range of 10³ to 10¹² ohm.
Application areas of Minatec CM pigments are:
- bright, decorative, antistatic surface coatings, e.g. flooring, computer housings
- antistatic packaging for voltage sensitive products in the microelectronics field
- bright and colored conductive surfaces on non-conductive materials for subsequent electrostatic painting
- bright colored conducting surfaces in clean room conditions which attract little dust
- giving antistatic properties to non-conductive materials, e.g. wood, plastic, paper or cartonboard
Structure and Properties
The basis of Minatec CM pigments is the layer-substrate principle in which mica as the substrate is coated with inorganic metal oxides. There are two types of Minatec CM pigments:
Minatec 31CM Pigment
- mica coated with a layer of tin oxide doped with antimony
Minatec 40CM Pigment
- mica/SiO2 coated with a layer of tin oxide doped with antimony
Minatec 31CM Pigment is practically transparent while Minatec 40CM Pigment has higher hiding power. Also, Minatec 40CM Pigment has more powder conductivity.
Color and Styling In contrast to conductive carbon black, Minatec CM Pigments have the advantage of a light color. Therefore, by mixing with other colorants, a large range of different colored conductive coatings can be obtained.
Minatec 40 CM Pigment has a light gray color. In many color mixtures it has a brightening effect that makes it excellent for pale or pastel colored formulations.
Minatec 31CM Pigment is a good pigment for creating conductive coatings with intense color shades. It has a highly transparent blue-grey color.
