Description
Chem-Set 633 5-Minute Gel Epoxy is a fast-setting, two-part gel adhesive designed for bonding porous surfaces such as granite, marble, wood, and concrete. With a working time of just 4–7 minutes and handling strength achieved in 10–15 minutes, it’s the professional’s choice for quick, durable bonds in the shop or on the jobsite.
This 633 5-Minute Gel Epoxy cures to an opaque finish and is ideal for vertical applications and gap-filling where traditional adhesives might sag or run. Whether you’re securing natural stone countertops, anchoring wood trim, bonding decorative concrete, or completing structural repairs, Chem-Set 633 offers consistent, reliable results.
Available in a variety of cartridge sizes, Chem-Set 633 integrates seamlessly with static mixing nozzles and standard dual-component dispensing tools. For best application, pair it with our professional epoxy dispensers to ensure clean and even material flow.
