LP-Paste Metallic 500
Heavy-Duty Metallic Elastomeric Emergency Repair Compound
Tensile Adhesion: ≥ 3.2 MPa |
Thixotropic Non-Sag Formula |
Standards: ISO 4624 / ASTM D4541|
LP-Paste Metallic 500 is a high-performance, two-component metallic-reinforced elastomeric repair paste designed for emergency leak sealing, seam reinforcement, and structural repair on metal tanks, pipes, and stainless steel assemblies. Formulated with zero-sag thixotropic properties and excellent damp-surface adhesion, it cures to form a dense, impact-resistant, chemical-proof seal that prevents fluid migration under pressure.
Key Performance Features
Non-Sag Thixotropic Paste
Heavy-paste consistency allows effortless vertical and overhead application on metal joints, pipe seams, and tank corners without slumping.
Damp Surface & Submerged Adhesion
Specially engineered to bond strongly onto damp or water-sweating metallic surfaces, enabling rapid emergency repair during active operations.
High Adhesion to Stainless & Alloy Steel
Metallic-reinforced matrix achieves exceptional tensile bond strength (≥3.2 MPa) on stainless steel, galvanized steel, cast iron, and aluminum.
Chemical & Corrosion Resistance
Resists water, mild acids, industrial alkalis, fuels, and oils, preventing galvanically induced corrosion along metal seams.

Application & Surface Prep Guide
Surface Preparation & Degreasing
Degrease metal surface using industrial solvent. Grit-blast or mechanically grind metal using a wire wheel/sanding disc to obtain a clean, rough metallic anchor profile.
Mixing Ratio & Homogeneity
Mix Component A and Component B according to the specified mixing ratio (1:1 or 2:1 by volume/weight as specified on label) on a clean mixing board until a uniform metallic grey color without streaking is achieved.
Application & Pressure Tooling
Apply LP-Paste Metallic 500 using a putty knife or spatula. Press firmly into seams, pitted areas, or crack gaps to expel trapped air and ensure 100% surface wet-out. Build up layer to minimum 2–3 mm thickness over joint margins.
Curing & Post-Processing
Allow to cure at room temperature. After full cure (24 hours), the compound can be sanded, drilled, painted, or mechanically machined if required.
