RTH-USA PROTEPLAST-60 Plastic Refractory Mass 11 lb (74 fl. oz.)

PROTEPLAST-60 Plastic Refractory Mass is a high-alumina, chemically bonded and ready-to-use repair material engineered for advanced thermal maintenance.

What sets it apart is its plastic, moldable consistency. This mass is easy to apply by hand or tool, allowing it to conform precisely into cracks, seams, or surface voids in firebrick linings and refractory installations.

Capable of withstanding temperatures up to 3000°F (1650°C), PROTEPLAST-60 is ideal for repairing erosion, thermal damage, and seam separation in industrial heat-processing equipment.

Each 8 lb (74 fl. oz.) pail provides excellent handling, adhesion, and thermal endurance — trusted by DIY enthusiasts and professionals for its unmatched ease of use and durability in extreme conditions.

Key features:

• Maximum Refractoriness: Withstands temperatures up to 3000°F (1650°C), perfect for high-intensity thermal environments.
• High-Alumina Composition: Ensures superior thermal shock resistance, mechanical strength, and long-lasting durability.
• Moldable Plastic Consistency: Unlike traditional cement or mortar, this is a plastic refractory mass — highly formable, pliable, and ideal for packing, patching, or reshaping damaged refractory surfaces.
• Precision Repair Capability: Perfect for restoring damaged areas in firebrick linings, patching cracks and joints in refractory cement or brick structures, and rebuilding eroded insulation layers.
• Chemically Bonded: Offers enhanced adhesion and service life under repeated thermal cycling.
• Versatile Applications: Suitable for local repairs and maintenance of kilns, furnaces, fireplaces, pizza ovens, stoves, boilers, incinerators, and other high-temperature units.
• Ready-to-Use Formula: No additives or preparation required for the product; simply open and apply.
