Instructions for Use

  1. Urethane resin foams due to moisture. Be careful of moisture while working.
  2. The ingredients may separate or the filler may settle. Stir well before use.
  3. Calculate the required main and hardening agents based on the mixing ratios listed in the product information.
  4. Measure the main agent and hardener into a polyethylene cup.Do not use paper cups because they contain water.
  5. Mix agent A and agent B well. Use a stirrer or spatula for mixing.
  6. When stirring, make sure to agitate the corners and bottom of the cup.
  7. Defoam the mixed liquid immediately after stirring. Insufficient defoaming may cause air bubbles.
  8. Pour or apply the mixture. The base material and case should be heated and dried sufficiently. Failure to do so may result in foaming.
  9. Curing should be done under the specified curing conditions.
