- Adhesion promoter for molding RTV-2/LSR onto conductive silicone rubber
- Application Details
- After stiring up POWERSIL® 79032 is ready-to-use. At room temperature the pot life is at least several weeks.
- Surfaces to be treated should be dry and free of grease, oil and other contaminants. For cleaning chemically pure solvents e. g. acetone can be used.
- The dispersion of POWERSIL® 79032 can be applied by dipping, spraying and with a brush. For electrically conductive coatings we recommend a curing - after air drying for approx. 5 min at room temperature – of at least 30 min at 150°C.
- POWERSIL® 79032 can also be used as adhesion primer for overmoulding parts made from conductive silicone rubber with RTV-2/LSR silicone rubbers. For adhesion promoting (e. g. for deflectors) POWERSIL® 79032 should be vulcanized – after air drying for approx. 5 min at room temperature – for 20 min at 140 – 150°C in a circulating air oven.
- Normally for this application POWERSIL® 79032 is diluted in a 1:1 ratio with Xylene. Casting with a RTV-2/LSR silicone rubber should take place at the latest after 24h.
- It appeared that the adhesion after heat vulcanization (e. g. 100°C) mostly is better than after room temperature curing. By dilution with chemical pure Xylene up to a ratio from 1:1 any desired mixing-viscosity (> 500 mPa s) can be adjusted. As a general rule the individual processing conditions must be optimized for the specific application.
- Various substances can poison the platinum catalyst and delay vulcanization or, in extreme cases, prevent it entirely. Particularly critical catalyst poisons are: Sulfur, polysulfides, polysulfones and compounds containing sulfphur, such as natural and synthetic rubber.
- Amines, urethanes and substrates containing amines, such as polyurethanes, epoxy resins etc. Organometallic compounds, especially organo-tin, and substances containing such compounds. Sticky areas are signs of inhibition.
