Trial workflow

How to prepare the first evaluation

  1. 01

    Pre-dry the resin and additive for 2 hours before the first evaluation.

  2. 02

    Start within the dosage listed in the TDS and prepare a controlled comparison sample.

  3. 03

    Recheck flame behaviour after any change to resin, filler, colour or sample thickness.
