According to DIN 55 990, the gel time of powder coatings is the time required to melt a specimen at a laid down temperature, using a specific test apparatus, and to achieve a gel - like consistency.
For the determination of the gel time of powder coatings, our Heating Block PL in accordance with the German Standard DIN 55 990 (ref. 30.45) with a spherical depression (mould) is used.
The temperature is precisely controlled with our temperature controller TC-3 (Ref. 70.05).
