ELASTOSIL RT 607 A/B RTV-2 SILICONE RUBBER / ENCAPSULANT Product description compound must not come into contact with this component. ELASTOSIL RT 607 A/B is a pourable, addition- curing RTV-2 silicone rubber. The two components should be thoroughly mixed at a 9 : 1 ratio by weight or volume. Special features To eliminate any air introduced during dispensing or trapped under components or devices a vacuum - two-part, 9 : 1 mixing ratio encapsulation is recommended. - low viscosity - rapid heat cure Curing: - high hardness Curing time of addition curing silicone rubber is highly - excellent heat stability dependent on temperature, size and heat sink - flame retardant properties of the component being potted. The reactivity can be adjusted within wide limits by Application adding Catalyst EP or Inhibitor PT 88 to suit the processing requirements of the particular application. - general purpose Encapsulant Catalyst EP increases the reactivity, i. e., pot life and curing time are reduced. Inhibitor PT 88 is a pot life extender and prolongs pot life and curing time. Processing Further information is given in our leafletCatalyst EP/Inhibitor PT88 . Caution: Only components A and B with the same lot number We recommend running preliminary tests to optimize may be processed together conditions for the particular application. Comprehensive processing instructions are given in To ensure homogeneity of the material, the our leafletWacker RTV-2 Silicone Rubber - components must be stirred thoroughly before they are Processin. removed or processed in their containers, in order to uniformly disperse any filler that might have settled during storage. Surface preparation: All surfaces must be clean and free of contaminants that will inhibit the cure of ELASTOSIL RT 607 A/B. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine Storage containing materials and organometallic compounds - especially organotin compounds. If a substrate s ability The Best use before end date of each batch is shown to inhibit cure is unknown, a small scale test should be on the product label. run to determine compatibility. Storage beyond the date specified on the label does Mixing: not necessarily mean that the product is no longer Component A of ELASTOSIL RT 607 contains the usable. In this case however, the properties required platinum catalyst, component B the crosslinker.
