Mastic 85 is a durable and insulating refractory composition designed for the fabrications of launders and the joining, bedding and patching of precast refractory shapes. Its consistency permits application by caulking, troweling, or hand forming and dries to a strong, hard and erosion resistant surface.
- Non-wetting to molten aluminium, magnesium and zinc
- Spreads easily and finishes smoothly, resulting in faster and better construction
- Exhibits lower shrink than comparable products, reducing joint maintenance and metal penetration
- Formulated to form secure bonds with all standard refractory materials
- Available in caulking tubes and pails, and is formulated with an anti-freezing protectant to prevent damage during transport
