Uses: For protection against corrosion and the water-proofing of pipes, flanges and valves for marine use. Compound: A neutral compound based on saturated petroleum hydro carbons (petrolatum) with inert fillers. Fabric: Fabric carrier free from chemical impurities, fully impregnated and coated on both sides. Characteristics: Unalterable in composition and plasticity over a wide range of temperatures. Slight superficial oxidation occurs in atmospheric application and renders the surface less tacky. Has a very high degree of impermeability to water. Won’t crack or harden. Unaffected by vibration and highly resistant to mineral acids, alkalis and salt.
