Engineered Composites Expert Witnesses

Engineered composites expert witnesses may opine on vinyl chloride polymers, electroactive polymers, functional polymers, and more. Here, the International Cast Polymer Alliance describes cultured marble, cultured granite and cultured onyx:

Cultured Marble, Cultured Granite and Cultured Onyx, as their names imply, have the look of genuine marble, granite or onyx. Cultured marble, granite and onyx products are usually manufactured with a high-gloss coating, called a “gel coat”, applied during the manufacturing process, which becomes an integral part of the cultured marble, granite or onyx product. Colorants may be added to the polymer/filler matrix in a manner which provides a “veining” which mimics the appearance of natural products. The polymer casting process yields a rock hard, durable product which takes on the look and feel of the natural product.
