With condensation cross-linking, the B component – a product containing organotin designated as Wacker T-series catalysts – is added in a concentration of between 2 and 5 percent to the corresponding component A. The crosslinking process creates a volatile alcohol compound as a byproduct, leading to a slight shrinkage in volume.
Please note: It is not advisable to speed up the crosslinking by increasing the temperature. The cured rubber cannot be thermally stressed until the by-products have completely evaporated.
- The curing is not impaired by inhibition
- The curing rate can be adjusted to a certain degree by varying the amount of catalyst and/or choosing a slow or fast catalyst
- Excellent reproduction accuracy and excellent release properties
