A color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with copper, zinc, an alloy of copper, or an alloy of zinc first layer which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides an optically variable reflection of light impinging thereon and a third layer encapsulating the second layer and being selectively transparent to light directed thereon.

A method and system () of fabricating elastomeric compounds is provided. The method includes the steps of establishing a thermo-kinetically heated high speed mixer () and introducing into that high speed mixer () in predetermined quantities a comminuted rubber composition (), a plasticizing agent composition (), and at least one additive composition (). The method includes the further step of simultaneously mixing and thermo-kinetically heating the comminuted rubber (), plasticizing agent (), and additive compositions () in the high speed mixer () for a predetermined residence time period to form a first intermediate mixture composition. The first intermediate mixture composition contains a substantially homogenous mixture of the comminuted rubber (), plasticizing agent (), and additive compositions (). The first intermediate mixture composition is introduced with a plastic composition into a heated multi-stage extruder () to form a second intermediate mixture composition extrusively shaped to a predetermined sectional contour. The second intermediate mixture composition is thereafter dried to form an elastomeric compound.

A precious metal color effect material is composed of a plurality of encapsulated substrate platelets in which each platelet is encapsulated with a first layer selected from the group consisting of silver, gold, platinum, palladium, rhodium, ruthenium, osmium, iridium and the alloys thereof, which acts as a reflector to light directed thereon, a second layer encapsulating the first layer in which the second layer provides an optically variable reflection of light impinging thereon and a third layer encapsulating the second layer and being selectively transparent to light directed thereon.

A lamellar particle is coated with an amorphous metal oxide hydrated gel which is then converted into a hydrophobic metal hydroxide-organic composite polymer film. The resulting product can be combined with a powdery film-forming polymer to produce a film-forming composition which can be applied by electrostatic coating. It also has significantly enhanced performance in plastic masterbatching, hydrophobic cosmetic formulations, and liquid paints and numerous other applications where a hydrophobic pigment is advantageous.
