HIGH TEMPERATURE MEMBRANE NO. 89

 

Sauereisen High Temperature Membrane No. 89 is a single-component, asphaltic mastic recommended as an impervious membrane under corrosionresistant monolithic linings or acid-resistant brick masonry for the protection of metal or concrete substrates. Spray application with airless equipment results in a flexible coating resistant to acids, alkalies and salts associated with flue gas environments and substrate movement from temperature changes or other causes.

The product is not recommended for use in oil, grease and solvent environments. No. 89 is not generally recommended for continuous liquid immersion. No. 89 maintains excellent elasticity and adhesion to concrete or steel substrates over a temperature range of -60oF to 300oF.

    Dual Lining System

    • The combination of an Organic membrane and Inorganic acid-resistant monolithic potassium silicate refractory installed with minimal control/expansion joints that will resist the acid and temperature of this very harsh physical environment.
    • High Temperature Organic Membrane offers not only a corrosion barrier for concrete to penetrating sulfuric acid; but, also serves as a bond breaker between the refractory component overlay & concrete substrate.
    • Potassium Silicate Acidproof Concrete serves as the primary protection against the molten sulfur and related thermal & acid service condition. The refractory also provides a thermal barrier for the membrane component.
