Marine-Grade Elastomeric Repair Compound for Packing & Jointing

Protect and restore rubber-lined surfaces and flexible sealing systems with this high-performance, two-component elastomeric repair compound. Formulated specifically for the demanding marine environment, it cures rapidly to form a tough, rubber-elastic coating that provides long-lasting protection against abrasion, impact, erosion, and a broad range of chemicals. Ideal for repairing and re-surfacing pump impellers, valve liners, flexible joints, pipe couplings, and gasket surfaces, this compound ensures a permanent, watertight seal that withstands immersion in seawater and hydrocarbons.

Engineered for excellent adhesion to prepared rubber, steel, and aluminum substrates, this compound creates a seamless, non-porous barrier that prevents corrosion and wear. Its fast-curing nature allows equipment to be returned to active service in just a few hours, minimizing costly operational downtime. Whether used for routine maintenance or emergency repairs, this elastomeric compound is the go-to solution for ship engineers and maintenance crews, delivering superior performance in even the most challenging maritime conditions.

Safe to use above and below the waterline, this product offers exceptional flexibility and resilience, making it an essential addition to any ship chandler's inventory for packing and jointing repair tasks.

Frequently Asked Questions

What surfaces can this elastomeric repair compound be applied to?

It is designed for rubber, metal, and concrete surfaces commonly found in marine environments. It bonds well to vulcanized rubber, steel, and aluminum, making it ideal for repairing flexible joints, gaskets, pump linings, and protective coatings.

Can the product be applied underwater or on wet surfaces?

Yes, the product is formulated to cure under water and on wet surfaces. This makes it suitable for emergency repairs in marine environments without the need for dry-docking.

How long does it take to cure?

The compound sets to a rubber-elastic state within 2–3 hours at room temperature and reaches full mechanical properties after 24 hours. Working time is approximately 15–20 minutes after mixing.

Is the cured compound chemical and oil resistant?

Yes, it exhibits excellent resistance to a wide range of chemicals, including seawater, mineral oils, mild acids, and alkalis, as well as high-torque abrasion and impact.
