Application Method
General Instructions
  • The product is best used at temperatures between 65°F and 80°F. Temperatures below 65°F will slow the cure speed of the material and viscosities will be higher. Temperatures above 80°F will cause the material to cure faster and viscosities will be lower.
  • For consistent dispensing maintain temperature in the above mentioned range. For optimum bond strength and to insure maximum performance in the finished assembly mate parts together within the specified work time of the adhesive.
  • Make sure the bond joint has uniform coverage and that a sufficient amount of adhesive is in the bond area. It is important to have the adhesive applied, parts aligned and positioned, within the established work times for the product. To ensure maximum performance in the finished assembly parts should remain undisturbed until the fixture time is reached.

Storage & Handling

Storage Conditions
  • The product should be stored in a cool, dry place out of direct sunlight.
  • The shelf life of MP55300 is one year from date of manufacture.
  • Shelf life is based on the products being stored properly at temperatures between 55°F and 75°F.
  • Exposure to temperatures above 75°F will reduce the shelf life.
  • This product should never be frozen.
Handling and Clean-Up
  • Clean up is best before the adhesive has cured.
  • Cleaners containing NMP (N-methyl pyrolidone) or Citrus terpene provide the best results.
  • On cured adhesive repeat use may be required.
