The reaction rate of addition crosslinking silicones can be increased via platinum accelerators, thereby ensuring crosslinking at temperatures below 20 ° C. If the ambient temperatures is too high, the reaction can be slowed down using a retarder. For condensation curing silicone systems, the reaction time can be shortened by increasing the amount of crosslinker. The mixing ratio must not be changed. Crosslinkers for different processing times are also available for some silicone systems. It is essential to consult the technical data sheet in advance.
