Latex Rubber

The effect pigments Iriodin®, Colorstream® and Xirallic® are also used increasingly in latex products. Particularly popular are the colors Gold and Silver such as Iriodin 111.

The best effects on the most transparent materials possible
Opaque colorants and fillers reduce the luster and effect. To bring out the effect of the pigments as much as possible, the system should be as transparent as possible. This should be taken into account especially in the catalyzation of the latex.
 
All Merck effect pigments can be distributed easily in liquid systems: just stir in and process. For latex products we recommend fine particle pigments, since latex mixtures can be stretched to many times their original size after vulcanization, containing not elastic pigments. To prevent coagulation of the latex on the dry pigment surface, pigments should be pre-wetted with water before stirring in. Because they can be destroyed by high shear forces, we recommend adding them just shortly before processing – and always under the same speed and mixing time, in order to achieve good product consistency.
