| Product description: SILPURAN® 6740/40 A/B is a paste-like, easily-pigmentable two-component liquid silicone rubber compound with short curing time. Vulcanizates are noted for their self-adhesive properties to various substrates and excellent mechanical properties. Special features: SILPURAN® 6740/40 A/B meets selected test requirements of ISO 10993 and United States Pharmacopoeia (USP) Class VI. Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances. SILPURAN® 6740/40 A/B is a primerless self-bonding grade that adheres to various substrates. The bonding is improved by an ageing process (e.g. one hour at 100°C) or by a longer storage at room temperature. Because of the individual surface properties each substrate must be tested before mass production. If nesserary one has to check the development of adhesive properties over time and/or in an environment relevant to the application. Application: This grade is particularly suitable for the economical production of large series of injection molded articles. SILPURAN® 6740/40 A/B is designed for medical applications including implantation for < 30 days. Information provided by Wacker Chemie AG. |
