Solid surface products are manufactured with high performance resin systems such as acrylic and unsaturated polyester. They have very high filler content and do not have gel coats. These materials are used primarily in counter top and wall panel applications. A design benefit of solid surface materials is the ability to be machined to like wood, though special equipment and fabrication procedurs are required. They can be precisely cut and bonded to fit nearly any surface shape. Solid surface materials can also be routed for decorative edging which can be applied with specifically formulated adhesives. Since the colors goes clear through the product, scratches, chips and stains can be easily sanded out.
