Mixing
- In order to achieve optimum performance, the same lot number of QSil 573 A and QSil 573 B should be used.
- QSil 573 A and QSil 573 B should be thoroughly mixed prior to catalyzation.
Mixing by hand:
- Catalyze QSil 573 A with QSil 573 B at a 1:1 ratio by weight. Use a clean plastic or metal container of approximately 3 times the volume of the material and mix by hand.
- Accurate weighing of all components, on a suitable scale, is essential for optimal product performance when mixing by hand. Mix until the material is uniform with no visible striations.
Mixing and dispensing with automatic equipment:
Use a mixing system that will properly mix the QSil 573 A and QSil 573 B at a 1:1 ratio by weight.
De-aeration
- Air trapped during mixing should be removed by vacuum at 29 inches of mercury. During the process, the material will expand, and intermittent evacuation may be required.
- Machine mixed material does not normally need to be de-aired.
