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.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

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

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.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.
