Processing
- Surface preparation All surfaces must be clean and free of contaminants that will inhibit the cure of WACKER SilGel® 613. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds. If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.
- WACKER SilGel® 613 and ELASTOSIL® CAT PT (F, UV) should be thoroughly mixed at a 10:1 ratio by weight or volume.
Curing
Curing time of addition-curing silicone rubber is highly dependent on temperature, size and heat sink properties of the component being potted. Curing speed of the combination WACKER SilGel® 613 and ELASTOSIL® CAT UV (10:1) is highly dependent on UV-activation (UV/intensity and dose).
