Chem-Set Seaming Adhesive Blowout Sale, Expired or Near-Expired

Description

This structural adhesive blowout offers Chem-Set C-20 and C-30 seaming cartridges carrying expired or near-expired lot dating, priced well below standard cartridge pricing. The cartridges in this listing are genuine Chem-Set acrylic (MMA) seaming adhesive, the same chemistry used across the color-matched line for granite, quartz, and solid-surface countertop seams, sold here as a clearance lot rather than as fresh-dated stock.

Where this structural adhesive fits

Chem-Set C-20 and C-30 are two-part methacrylate seaming adhesives built for laminating, mitering, and integral-mounted sink and bowl seams in acrylic and polyester solid surface, along with granite, marble, and quartz. Fabrication shops running color-critical seams should treat this blowout lot as a value option for practice seams, non-visible joints, or shop testing rather than a guaranteed match for a customer-facing color program, since expired or near-expired dating can affect working time and final bond performance versus fresh stock.

How this structural adhesive is sold

Every cartridge ships as-is at the blowout price reflected on this listing, with no guarantee of full unopened shelf life remaining. Shops that keep general-purpose seaming adhesive on hand for practice runs, jigs, fixtures, or lower-stakes bonding can use this lot to cut material cost without touching current-dated inventory. Store cartridges at room temperature and use the standard C-20/C-30 dispensing gun and mixing tip already on hand for the fresh-dated line.
