What is the low temperature stability of the coating?
2017-05-23
The
national standard stipulates that the coating sample is packed in a
plastic or glass container of about 1 L, filled and sealed in a low
temperature box (-5 ± 2) ° C. After 18h, the container is removed and
placed at a standard temperature of 23 ± 2 ℃, the
relative humidity of 50% ± 5% of the environment for 6h, so repeated
three times, open the container, fully stirring the sample, observe
whether the lump, cohesion and separation phenomenon, if not that "no
deterioration." Low temperature stability of the
paint is to adapt to the actual construction conditions, as well as
product storage and transportation process safety.
