How to uses

  • Weighing: Weigh components A and B according to the mixing weight ratio;

  • Mixing: Mix the two components of the adhesive thoroughly and use specialized mixing equipment (such as a small mixer). When mixing by hand, pay attention to scraping the walls and stir the bottom and edges of the container thoroughly;

  • Defoaming: Vacuum degassing in specialized mixing equipment. Alternatively, the mixed rubber material and mixing container can be placed in a vacuum defoaming device and vacuumed for defoaming treatment. During the vacuum degassing process, the liquid level of the mixture may rise to 3-4 times the original volume, and then automatically burst and collapse. After breaking the bubble, maintain the vacuum for 1-2 minutes and release the vacuum;

  • Brushing or pouring molds: If the surface of the mold is relatively rough, a release agent can be applied to prevent sticking to the mold;

  • Mold taking


Package

  • N.W 25KG Iron Pail


Storage

  • To maintain all performance of our company's products, the adhesive should be used within 12 months from the date of production.

  • The storage temperature should be between -5 ℃ and+35 ℃, and it should be used as soon as possible after opening. A. Please seal and store component B away from light.
