Influence of temperature in storage and/or transport
In the technical documentation of all our product the minimum shelf life after production is given under a temperature between +5°C and + 25°C. When products are stored with higher temperatures this will shorten the shelf life.
As maximum temperature generally +45°C can be maintained. Above this temperature problems might occur, for instance too high pressure in canisters of PU foam. For neutral silicone sealant the chemical reactions can be changed.
Temperatures below +5°C until ca. -5°C do not directly cause problems. Below -5°C dispersion product scan freeze.
Within acid-containing silicon sealants crystallization of the cross linker can occur with temperatures below -5°C.
By warming this sealant above +5°C this crystallization can be made undone.
Sealants are used in building and industrial applications in many places under various circumstances on several substrates. It may occur that the sealant joints show discoloration after a couple of days or weeks. In general the joints can be considered...Read more
