Chem-Set 650UC Ultra Clear Stone Epoxy, 50 mL Cartridge

Description

Chem-Set 650UC is a clear stone epoxy built for bonding natural stone where the repair or seam has to disappear rather than stand out. It is a medium viscosity, liquid two part epoxy with a UV stable, optically clear cure, made for seams, lamination, and repairs on interior and exterior stone surfaces where appearance is as important as strength.

Where This Clear Stone Epoxy Is Used

Countertop fabricators reach for this clear adhesive on granite, marble, and engineered stone seams where a visible glue line would ruin the finished look of the slab. It also covers lamination work, building up edge profiles from two slabs to create a thicker-looking countertop edge, and cosmetic repairs on stone signage and metal fabrication projects that need a UV stable bond outdoors as well as inside a climate-controlled shop.

How the Clear Stone Epoxy Performs

Working time runs about five minutes, giving the fabricator enough time to position and align a seam or laminate before the epoxy begins to set, and the full cure follows in about an hour. That combination of fast set and short cure keeps a stone shop moving without long clamp times tying up a workbench, while the UV stable formulation resists yellowing so the seam stays optically clear long after installation, whether the piece sits by a window or outdoors.

Order with a compatible mix nozzle and dispensing gun sized for 50 mL cartridges, and stage the seam or laminate before mixing since working time is short. Browse the rest of the epoxy line for other viscosities and cure speeds. For mixing and seam technique demonstrations, see the Chemical Concepts YouTube channel.
