Post-hardening conditions: The test piece is cured at 105 ° C for 2 hours after 24 hours at room temperature.

Usage

1. The gel time can be changed when adjusting the curing ratio.
2. The gel time properties of V88LA/LB are affected by weather, temperature, hardener content, accelerator content and additives. Before changing the rate, it recommend to test the gel time in a small amount to facilitate the process.
3. Wear protective clothing and gloves during working.

Strorage

  1. The recommended temperature for storage should be below 300C to ensure the stability of the resin.
  2. Store in a cool place and away from direct sunlight. If the storage is too long, open the cap and blow in air to extend its storage time.
  3. Avoid exposure to heat and flammable liquid sources.
