Castozytte 99. A lightweight binder for Ceramics and Refractories. Registered brand of Mehran Ceramics

Lightweight Castozytte 99 is a proprietary, cement free, lightweight pumpable refractory product intended for application by pouring, pumping or pneumatic shotcreting. For pouring/ pumping placement, Lightweight Castozytte 99 is supplied as a two component system, including a colloidal silica binder, or for application by shotcreting, is supplied as a three component system, including the colloidal silica binder plus instant setters, a special chemical accelerant utilized to induce rapid material setting. The patented colloidal silica binder system provides a very fluid, self leveling refractory slurry that allows rapid material placement by pumping onto either hot or cold substrates, or by shotcreting, utilizing the accelerant that is injected into the pneumatic slurry propellant,
that results in minimal rebound waste. Lightweight Castozytte 99 exhibits excellent adhesion characteristics to refractory and metal substrates and develops strong bonding to itself or to other refractories with no laminations, even if applied during multiple, independent placements, regardless of the time intervals between placements. After heat up, Lightweight Castozytte 99 forms very strong bonding to virtually all undeteriorated refractory materials and requires minimal dry out time, which reduces component
downtime and increases availability and in service, exhibits exceptional strength properties.

Application

Lightweight Castozytte 99 is recommended for new lightweight refractory linings or hot or cold repair or replenishment of existing lightweight refractory linings, including in the blast furnace and similar metallurgical process vessel applications, whenever a lightweight castable/pumpable/ shotcretable product is required.
