Rex Materials makes a variety of repair products for your table or launder refractory. With a variety of moldables and coatings, we have the right repair product for you!
Pyroform E-Z Fill™ is Rex Materials' premium joint and crack repair compound. It was developed specifically to spread easily and finish smoothly for faster and better joint construction. Pyroform E-Z Fill™ is formulated to securely bond between sections of Pyroform HP™, HP-45, Pyrolite® and other refractory segments. It has very good strength and abrasion resistance for long life.
Pyroform E-Z Fill™ has the lowest thermal shrinkage of any comparable product, reducing the chance of joints opening and allowing metal penetration.
Pyroform E-Z Fill™ is extremely non-wetting to molten aluminum, Magnesium and Zinc and when coated with Pyroform Sealer™, creates a surface that is truly impervious.
Pyroform E-Z Fill™ is available in convenient caulking tubes, as well as one, five, and fifty-five-gallons (3.8, 18.9, and 208 liters) containers. It is caulkable and pumpable for large repairs or use as a back-up insulation material.
Surfaces to be bonded must be clean and free of loose particles, dust and release coating. Curing takes place through normal air drying. Low temperature heat (up to 200°F or 95°C) can be used to accelerate the process, if necessary. This can be accomplished using a hot air blower or low velocity flame.
Pyroform E-Z Fill™ is supplied with a freeze protectant to prevent damage during transport. The product should be stored between 40°F (4°C) and 90°F (32°C). Under these conditions, the normal shelf life is one year. In temperature and humidity controlled storage, a shelf life of two + years may be expected.
For higher temperature applications where, molten metal is not present, such as furnace repairs above the metal line or for back-up insulation, try our Pyroform E-Z Fill™. It can be used in environments up to 2300°F or 1260°C.
Pyroform Extender™ is an all-purpose refractory patch compound. Its low shrinkage, excellent thermal shock resistance, and good adherence make it suitable for many uses. Pyroform Refractory products can be patched or repaired with Pyroform Extender™. Pieces can be joined together using Pyroform Extender™ as a cement application. All surfaces where Pyroform Extender™ is applied must be clean and dry. Apply with a trowel, putty knife, or caulking device. Pyroform Extender™ is packaged in airtight containers and should be kept from freezing.
Pyroform Sealer™ is a surface preparation agent for Pyroform Refractory products. Pyroform Sealer™ is a high alumina product formulated specifically to assist in the resistance of molten aluminum attack. Its slightly dusty surface acts as a release layer to prevent adherence of molten aluminum. For other molten metals, we offer a special Sealer suitable for applications up to 3000°F(1650°C).
Application. Pyroform Sealer™ should be mixed thoroughly before each use (stir or shake). Surface to be coated must be clean and dry. Any application method which produces a uniformly thin coating, such as brushing, rolling, dipping or spraying may be used. NOTE: Heavy coatings may have a tendency to chip or flake. Coating must be dry before contact with molten metal. Pyroform Sealer™ achieves its highest strength and erosion resistance after service above 1200°F (650°C). When you see "gray” areas on the Pyroform then it's time to sand they area and re-seal it with Pyroform Sealer. Standard release coatings like boron nitride are recommended over the sealer for addition resistance to aluminum adherence.
Pyroform Sealer must be used as a top coat when using E-Z Fill or Pyroform Extender to make repairs.
Pyroform E-Z Pour™ is a pourable, granular material specifically designed for use as back-up insulation in irregular areas where conventional insulation materials (blankets and boards) cannot fit. Pyroform E-Z Pour™ is simple to install and requires no mixing, drying or curing. In fact, equipment can go into service immediately after the installation is complete. In addition, Pyroform E-Z Pour™ has a low thermal conductivity and excellent resistance to molten aluminum. These features make Pyroform E-Z Pour™ an ideal choice for casting tables, distribution launders and transfer launder systems.
Installing Pyroform E-Z Pour™ is as easy as 1-2-3. After setting the refractory lining in place, simply:
That's all there is to it - no mixing, no drying, no hassle.
Removal of Pyroform E-Z Pour™ is just as easy. After removing the old refractory, simply sweep or vacuum the Pyroform E-Z Pour™ and you're done.
Pyroform E-Z Pour™ is supplied in convenient five gallon containers which hold 22 lbs. (10kg) of material or economical bags that hold 60 lbs. (27 kg) of material. Each five gallon container is equipped with a handy pouring spout to make the installation even easier. An optional spout extension is available) for hard-to-reach areas. If alternate packaging is required, contact our Customer Service Team to discuss other options.
