Trial workflow

How to prepare the first evaluation

  1. 01

    Blend the grade with PMMA resin for 5–8 minutes before processing.

  2. 02

    Keep the base resin, thickness and processing conditions consistent between comparison samples.

  3. 03

    Evaluate the stabilized molded result after at least 24 hours.
