Overview of Belzona 1818
A two-component, fast curing, surface tolerant abrasion resistant system ideal for patch repairs on surfaces subject to high erosion. Belzona 1818 stands out for its ability to bond to damp, wet, underwater, and oil-contaminated surfaces, enabling repairs in environments where surface preparation is limited.
Key Benefits
Bonds tenaciously even when surface preparation is minimal or substrate is contaminated
Outstanding resistance to erosion damage in flowing fluid and abrasive environments
Rapid return to service after application
Easy to mix and apply without specialist tools
100% solids formulation reduces health and safety risks in confined spaces with no shrinkage on cure

Frequently Asked Questions
What is Belzona 1818 (Surface Tolerant Abrasion Resistant) used for?
Belzona 1818 is a 2-part fast-curing surface-tolerant abrasion-resistant system ideal for patch repairs on surfaces subject to high erosion. It bonds to damp, wet, underwater, and oil-contaminated surfaces, enabling repairs in environments where surface preparation is limited.
Can Belzona 1818 be applied to wet or oily surfaces?
Yes. Belzona 1818 maintains strong adhesion when applied to wet, underwater, and oil-contaminated substrates. Pull-off adhesion remains over 2,000 psi on grit-blasted steel even when the substrate is contaminated with transformer oil or under water.
How fast does Belzona 1818 cure?
Belzona 1818 has a working life of 16 minutes at 68°F (20°C), and supports light mechanical loading after just 2 hours at 68°F (20°C), making it well-suited for emergency repairs and fast return-to-service requirements.
