BNZ Materials | Insulating Fire Brick

BNZ Materials’ Marinite Insulating and Finishing Cements are air-setting materials, mixed with water and applied in plastic form. They are designed for application to irregular surfaces where it is impractical to cut and apply pipe, block or other insulating products.

In addition to providing a pleasing, smooth surface appearance, BNZ cements fill voids and seal against heat losses. These strongly adhering insulations offer a hard surface which can be painted or weather-proofed if service temperatures are appropriate.

Insulation of small steel pipe fittings. Leveling. For warped steel furnace shells prior to installing refractories. Finish coat over block insulation. Repairs. For damaged block and pipe insulation. Irregular Fill. For areas in refractory backup insulation where other types of insulation would be difficult to apply. Easy to Use. Mix with water and apply with trowel or shovel. Reduce Inventory. Ideal for plant maintenance inventory to reduce number of items used for small jobs. Reduce Construction Costs. Eliminate field cutting of block insulations for insulating irregular areas.		508 Insulating Cement. An 1800°F service product, utilized in the refractory applications requiring a combination of insulating value and high temperature performance. [ download MSDS] 460 Insulating Cement. A 1600°F product, provided in higher density than 508 Insulating Cement. 460 Cement can be applied in heavy layers. It is frequently used as the principal covering on pipe sizes smaller than 4", then covered with a finish of 375 Finishing Cement. [ download MSDS] 375 Finishing Cement. A one coat finish which hardens to a smooth, crack-free surface in a few hours. This surface may then be painted with a water-base paint. Recommended for insulating small steel pipe fittings and as a finish over nonabsorptive insulating surfaces or under very slowdrying conditions. Service temperature limit is 1400°F. [ download MSDS] 375-L Insulating Cement. Used specifically in the aluminum industry as a filler material and trough liner, 375-L Insulating Cement is a 1500°F product [ download MSDS]		The physical and chemical properties of BNZ's Insulating and Finishing Cements represent typical average values obtained in accordance with accepted test methods and are subject to normal manufacturing variations.
