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 surface fillers come in a pen for precision application. After applying, use the LED on the back of the pen to instantly cure.

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

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

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

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

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

Prepare joints and surfaces to ensure proper sealant adhesion.

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.

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

These sealants don't degrade in sunlight.
