Description
Stone Seam C-20 is a two-part methacrylate, non-yellowing, hard surfacing, high strength seaming / surfacing adhesive; the latest generation of color-matched adhesives for the surfacing industry. Available in more than 100 pre-mixed colors, C-20 was developed for modern demanding fabrication methods such as laminating, mitering, integral mounted sinks and bowls, and applications subject to dynamic loads. Chem-Set C-20 produces improved bond strength over similar products. Fabricators benefit from our increased color choices, as C-20 is used universally on acrylic and polyester solid surface materials as well as granite, marble, quartz surfaces, ceramics, and more!
