Carboline (St. Louis, Missouri, USA) recently released Thermo-Sorb 263 and Thermo-Sorb E as intumescent coatings compliant with low-volatile organic compound regulations.
Each product is designed as a durable, decorative, and fast-drying fire protection solution for commercial and light industrial applications.
These solvent-based intumescent coatings offer a decorative finish as well as excellent resistance to high humidity, wet/freeze/thaw cycling, ultraviolet exposure, and atmospheric weathering. The intumescent reaction and resulting char production slows the rise of the steel’s temperature, allowing it to maintain its strength longer.
The Thermo-Sorb 263 provides up to 4 h of cellulosic fire protection for interior structural steel, while the Thermo-Sorb E provides up to 3 h of cellulosic fire protection for exterior steel. Both can be applied in lower temperatures than many water-based systems.
“In addition to providing functional coatings in a competitive industry, the fireproofing products we develop protect against loss of life by ensuring the integrity of the steel,” says Ed Taylor, fireproofing laboratory manager.
