Thiokol® 2369 is semi-flexible epoxy novolac coating that has been formulated to provide maximum chemical resistance to 98% sulfuric acid and other aggressive chemicals. The coating's unique formulation incorporating polysulfide polymer into the backbone of the epoxy chain prevents "age hardening" to provide both durability and concrete compatibility. In addition, Thiokol 2369 has excellent impact and thermal shock resistance while maintaining long-term flexibility. Call 281/379.0033.
