Description
LORD 7602 is a one-part, moisture-cure urethane calk built to seal and bond in the same step. Unlike the two-component structural systems in the LORD line, this is a single-component product that ships ready to gun straight from a standard 1/10 gallon (10.3 oz) cartridge, with no resin-and-curative mixing to manage on the line or in the shop.
### Where This Calk Fits
Seam sealing, panel joint filling, and general weatherproofing on truck bodies, trailers, and equipment enclosures are the natural home for LORD 7602. Because it cures on contact with ambient moisture rather than a second component, it works well for field repairs and touch-up work where mixing two parts is impractical. The cartridge format loads into any standard caulk gun, so no dedicated dispensing equipment is needed to lay a bead.
### How This Calk Holds Up
Once cured, LORD 7602 forms a flexible, weather-resistant seal that moves with the joint instead of cracking at the seam. The urethane chemistry gives it solid adhesion to metal, painted surfaces, and many plastics without a separate primer step on most substrates, and the cured bead resists water, road spray, and general outdoor exposure over the life of the seal. Moisture-cure systems set from the outside in, so thicker beads take longer to fully cure through than a thin fillet.

Store cartridges with the tip capped or plugged between uses, since an open tip will skin over as it picks up moisture from the air.
