SILPURAN® 2420 A/B can be used for flexible molding applications in in orthopedic technology.
Processing
- The components A and B of SILPURAN® 2420 A/B are mixed homogeneously in a ratio of 1 : 1 and vulcanize rapidly at temperatures over 100°C.
- In a given application the required curing conditions (temperature and time) will also depend on the size and thickness of the specimen.
- Detailed instructions for preparation and use are given in the brochure “Room Temperature Vulcanizing (RTV) Silicones - Material and Processing Guidelines”
- Important note : The platinum catalyst is in component A.
- Caution : Only A and B components with the same batch number may be processed together
