Important Instructions

  • Because Grand Rapids Rubber cannot anticipate or control every potential application, we strongly recommend testing of this product under individual application conditions prior to commercial use.
  • When using PSA options, surfaces must be clean and free of oil, grease, moisture, dust and dirt. Isopropyl alcohol is good for cleaning the surface. Do not remove liner until tape is in proper position. Avoid touching adhesive surface before application.
  • Recommended service temperature of base sponge is -100°F to 500°F (-73°C to 260°C).

Shelf Life

10 years after the date of sale for base material when stored in original packaging at temperatures up to 70°F (21°C) and 50% relative humidity (see the applicable data sheets for pressure-sensitive adhesive options).
