## Overview

Sikaflex-291i is a 300ml steel grey polyurethane sealant designed for demanding marine environments. It offers exceptional adhesion across diverse materials, high elasticity for vibration resistance, and a paintable finish for aesthetic flexibility. Resistant to fresh and saltwater, it meets strict marine standards while maintaining low emissions for eco-friendly use.

## 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.

Review: Sehr gute Qualität - Lässt sich gut verarbeiten, Sikaflex ist eben eine gute Marke

## Features

- Adhesive strength: Sikaflex-291i has an excellent adhesion spectrum and can be used on various surfaces such as wood, metal, ceramic, glass and plastic
- Elasticity - This strong adhesive sealant is highly elastic and therefore ideal for applications where a certain mobility is required, such as the grouting of windows or doors
- Paintable - This marine adhesive can be painted over after curing. This is especially advantageous for visible joints, which are to be painted later
- For marine areas - Resistant to fresh and salt water, this marine sealant is versatile and suitable for sealing on boats and ships
- Low emission - This sealant is an environmentally friendly choice. The isocyanate and emission values are low, so the adhesive contains only minimally volatile organic compounds
