Three Bond 1121 - Nichttrocknende Esterharz-Flüssigdichtung - 20 kg Eimer

Three Bond 1121 – Ester Resin Liquid Gasket Overview

The Three Bond 1121 is a non-drying ester resin liquid gasket, available as a 20 kg bucket. As a solvent-free sealant, it is characterized by its sticky surface texture and forms seals on surfaces without curing. The gasket is particularly suitable for large-area applications, such as flange connections and ship hatch covers.

With high gasoline and oil resistance and a low-odor formulation, it meets typical requirements in marine and industrial installations where guaranteeing tightness and clean processing is important. The gray color facilitates inspection and cleaning in harsh environments.

Suitable for Flange Connections and Large Surfaces

Removable Flange Connections

The gasket shows very good removability, enabling maintenance without damage to sealing surfaces. This simplifies regular material changes and inspections.

Large-area Applications

For large sealing areas such as ship hatch covers, 1121 provides consistent sealing performance and a low tendency to sticking, even with extended service life.

Properties & Benefits

Thanks to the solvent-free formulation, the condition of the sealing surfaces remains unchanged, and the material can be reliably applied. The gasket provides flexible adaptation to uneven surfaces and maintains sealing performance under temperature changes and operating loads.

Processing & Practical Use

Before mounting, thoroughly clean surfaces, dry them, and keep them free of grease. The sealant is applied in a liquid state and remains malleable for a long time without curing – ideal for assemblies that require readjustment.
