LORD - Model HPC-5B - Coating
LORD HPC-5B coating is a one-component, room temperature curing HNBR coating which features robust adhesion and exceptional mechanical properties. This coating greatly enhances fluid and ozone resistance for a wide variety of elastomeric substrates. LORD HPC-5B coating is black. Coating is composed of a mixture of polymers, organic compounds and fillers dissolved or dispersed in an organic solvent system.
Shelf life is one year from date of shipment when stored at 21-27°C (70-80°F) in original, unopened container. Do not store or use near heat, sparks or open flame.
Keep the container tightly capped when not in use to prevent solvent evaporation and moisture contamination.
Excellent Adhesion – provides strong adhesion to substrate and elongation of up to 600%; properly applied coating does not crack or peel. In laboratory testing, coating has demonstrated that it will not peel or crack prior to substrate cracking.
Fluid Resistant – provides fluid resistant barrier to external surface of elastomeric part, allowing bulk of component to be made of less expensive, less fluid resistant material. Resultant system offers low cost, high mechanical properties with high fluid and environmental resistance. LORD HPC-5B provides excellent resistance to lubricating oils and transmission fluids. For long term fluid resistance against very aggressive fuels such as Jet A fuel, LORD HPC-3 coating should be evaluated.
Ozone Resistant – provides ozone resistant barrier to external surface of elastomeric part, allowing bulk of component to be made of less expensive, less ozone resistant material. Resultant system offers low cost, high mechanical properties with high ozone resistance.
Convenient – applies easily by spray, brush, dip or roll coat methods; can be easily incorporated into existing production lines. Coating cures at room temperature or with the aid of hot forced air.
