A product safety data sheet should be obtained from your BRB office prior to use.
Special instructions
The addition of silicone oil is a form of adjusting your silicones. You should be aware that the final values, will differ from the values indicated on the data sheets of the silicone.
Oil does not actively participate in the silicone network. This means it will be able to migrate out of the silicone over many years. This proces is sped up when the silicone are under pressure or bend. This will result in a greasy layer on the silicone surface and possible shrinkage of the rubber.
