Sauereisen Fib-R-Thane is an elastomeric lining composed of fiber-reinforced, asphalt-modified urethane. Fib-R-Thane is used as a chemical-resistant membrane or gasket seal for the protection of concrete, block and steel. Available in two formulations, Fib-R- Thane No. 88T is applied by trowel, while No. 88S is the sprayable grade.
Fib-R-Thane has excellent adhesion to most substrates. As a high solids elastomer, it is recommended when movement from temperature change or other causes will be encountered. Nos. 88T & 88S resist acids, alkalies, and salts associated with flue gas immersion environments. The urethane content of Fib-R-Thane allows it to exhibit an improved resistance to oil, grease and solvents in comparison to standard asphalt.
Fib-R-Thane maintains excellent elasticity and adhesion over a temperature range of -30oF to 250oF. When subjected to mechanical stress, the lining has nearly 100% recovery.
