Ultra Demon Mortar protects internal boiler linings

April 16, 2020   Don Horne

The Plibrico Company today introduced Ultra Demon Mortar, an enhanced wet, air-setting refractory mortar that exhibits the thermodynamic stability required for the protection of industrial boilers, furnaces and incinerators that operate at temperatures as high as 3,000° F.

Engineered for superior strength and extended workability, Ultra Demon Mortar is a reliable, economical solution for laying up intermediate, high-duty and super-duty fireclay bricks.

Creamier in texture when compared to other mortars, Ultra Demon Mortar is exceptionally pliable, making it easier to install by troweling or dipping, and giving it a more predictable consistency over time. In fact, the workability difference over a period of 100 days is only five percent, and nearly 50 per cent better than the industry standard over a 45-day period. Improved workability on the jobsite translates to less waste and better material efficiency, all of which can lead to new paths to profitability for customers and installers.

Ultra Demon Mortar does not sacrifice strength for workability. In strength studies it scored twice as high as conventional mortars, ensuring minimal risk of damage related to thermal contraction. Unique binding materials deliver improved thermodynamic properties that reduce the risk of mechanical failure and enhance long-term adhesion. Along with traditional applications, these qualities also make Ultra Demon Mortar ideal for hot spot/fill injection when used with a suitable grout pump.

Plibrico Ultra Demon Mortar contains minerals high in aluminum and special aggregates for withstanding elevated temperatures and aggressive operating conditions that can severely damage the internal lining of furnaces, boilers, and vessels for holding and transporting metal and slag. These types of conditions are routinely experienced in aluminum and steel processing, power generation, oil/gas, mineral processing and incineration.

In field-testing of Ultra Demon Mortar, refractory installers said that they were capitalizing on the new mortar’s advantages. One installer’s testimonial summed up their experience this way: “Ultra Demon is the best mortar we have ever used. Don’t buy anything else.”
