Viscosity testing of T-Flow series Silicone for Mold

Tear strength testing of T-Flow series Silicone for Mold


  1. Stir Part A well before use, shake Part B catalyst container well before use.
  2. Weigh 100 Part A to 2~3 Part B using an accurate scale and a clean mixing container.
  3. Vigorously mix and scrape walls of the container, continue mixing until uniform.
  4. Place the mixture in a vacuum chamber & degass. If without a chamber, Pour the mixture 2-3 inches above the pattern in a thin stream.
  5. Allow the silicone to cure 2-4 hours and demold with care.

Important tips

  • Before use, read the operation manual, please.
  • Before large production, a small-scale test is recommended.
  • Mixing ratio must be accurate, recommend mixing ratio is A:B=100:2~3(by weight), If curing too fast, please reduce the ratio of catalyst to 1% or less, then Stir Part A and Part B completely.
  • Use a vacuum to de-gas this product before use under pressure. Vacuum silicone for 2-3 minutes
  • This product has a limited shelf life. Use it as soon as possible after opening.
  • Always tightly reseal containers after use. Air, moisture or other contamination causes a reduction in reactivity over time.
