Repair small leaks and cracks in coolant tanks for commercial vehicles and industrial equipment. These surface fillers meet ASTM D3147 for their ability to stop leaks in engine cooling systems.

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Clear enough to read through, these UV-resistant sealants allow optimal light transmission for use with solar cells and fiber optics.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Thinner than non-sag sealants, these flow easily into cracks and have a smooth finish.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start.

These sealants don't degrade in sunlight.

Prepare joints and surfaces to ensure proper sealant adhesion.
