ITW Dykem Cross Check Torque Seal White provides a highly visual method for detecting loose nuts and bolts. Highly visible under ambiant light, Cross Check marks are easily broken if parts are tampered with or become loose, providing excellent warranty protection. Safe for most surfaces, this tamper proof identification paste adheres well to metal and other substrates and dries to the touch in 30-40 minutes. Complete curation occurs in 7-10 days, with 80% curing occuring in 48-72 hours. Elevated temperatures or blowing hot air can reduce drying/curing process.
