Pyroform E-Z Fill^TM - Non-wetting Refractory Joint And Patch Compound

Pyroform E-Z Fill™ is Rex Materials’ premium joint and patch compound. It was developed specifically to spread easily and finish smoothly for faster and better joint construction. 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 up 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 to molten metal attack and oxide attachment.

Pyroform E-Z Fill is available in convenient caulking tubes, as well as, one, five and fifty-five gallon (3.8, 18.9 and 208 liter) 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 Pyrolite™ E-Z Fill. It can be used in environments up to 2300˚F or 1260˚C.
