SiSiB silanes can be used to crosslink polymers such as acrylates, polyethers, polyurethanes, and polyesters to improve
tear resistance, elongation at the break, tear propagation resistance, and abrasion resistance.
Crosslinker PC6151 and PC8151 are based on enoxysilanes, these silanes are used in electronic and cleanroom applications as they are not being absorbed on silicon wafers as e.g. oximes. Moreover acetone is not a VOC, they can be used for low-VOC-formulations.
Enoxy cured silicones have a particular advantage when being used in closed compartments at elevated temperatures. Contrary to oxime, alkoxy, acetoxy and similar systems they do not undergo a reversion reaction which may otherwise lead to a softening. |
