C-20 Seaming Adhesive Shore

Description

“Chem-Set™ C-20 Seaming Adhesive is a two-part methacrylate, ultra violet light stable, non-yellowing surfacing adhesive designed for the seamless bonding of solid surface (acrylic and polyester and blends), engineered stone, and natural stone products. Combined at a ratio of 10:1 (10 parts resin, one part activator), C20 adhesives have a working time of 10 to 15 minutes and achieve nearly 90 percent of its ultimate strength in 25 to 30 minutes at room temperature curing. C20 adhesives offer a combination of high strength, stiffness, and toughness as well as the ability to bond very strongly to a wide variety of solid surface materials. C20 adhesives provide high strength bonds to acrylic solid surface, polyester solid surface (both filled and unfilled), and alloy solid surface (combinations of both acrylic and polyester solid surface resins). C20 adhesive gives the fastest initial strength (green strength) and quickest routable time from dispensing of any of the contemporary adhesives in the market place.
