Introduction

A single-component solvent-borne intumescent fire protection coating for structural steel with ultra-thin film build.

Key properties

interior dry surfaces generally do not require a topcoat.

With a compatible topcoat for protection, the fire protection coating can also withstand weathering on its own for 12 months.
