860JF 600 mL Cartridge - Concrete Gray

- High-Performance Semi-Rigid Polyurea – SIMIRON 860JF is a high-performance, semi-rigid polyurea engineered specifically for filling control and construction joints in concrete floors — the right balance of strength and flexibility to handle floor movement without cracking or pulling out.

- Convenient 600 mL Cartridge Format – Pre-packaged in a 600 mL dual-component cartridge — loads into a standard dual-cartridge gun for fast, precise dispensing with no separate mixing required. Perfect for smaller jobs, repairs, touch-ups, and tight spaces where a 10-gallon bulk kit is more than the job needs.

- 100% Solids & VOC Free – Formulated as a 100% solids, VOC-free system — safe for indoor and food-grade environments, environmentally responsible, and free of the off-gassing and odor issues common with solvent-based joint fillers.

- Fast-Setting with Excellent UV Resistance – Fast-setting formula gets the floor back into service quickly, with a generous shave-time window for proper finishing. Excellent UV resistance for areas exposed to sunlight, and moisture insensitive — cures reliably even when concrete isn't perfectly dry.

- Concrete Gray Color Matches Most Floors – Concrete Gray shade blends naturally into the surrounding gray concrete substrate — ideal for warehouses, distribution centers, manufacturing facilities, and any commercial or industrial floor where the joint should disappear into the slab. Supports and protects joint edges from heavy loads and wheel traffic, reducing spalling.
