## Overview

Sikaflex-291i is a premium polyurethane-based multipurpose sealant designed for marine and general use. It offers exceptional resistance to ageing, weathering, salt and fresh water, with a tensile strength of 1000 PSI and a fast 6-hour cure time. Non-corrosive, paintable, odourless, and non-conductive, it ensures durable, vibration-resistant seals for demanding environments.

## Description

Resistant to fresh and salt water, as well as the strict requirements of various marine standards, Sikaflex-291i is the perfect sealant for the marine sector. Its high adhesion and elasticity make it the ideal sealant for particularly stressed joints in maritime environments. At the same time, the elastic property ensures that the joints are vibration resistant. Thanks to its unique polyurethane-based formula, the adhesive cures by humidity - at higher temperatures, this process is slightly faster, but slightly slower at lower temperatures.
