ELASTOSIL® Sub C 2002 A/B is the silicone rubber of choice to manufacture all types of thermal insulating devices

Main field of application: Thermal insulation material for marine applications, e.g. deep-sea constructions and subsea oil
production equipment.

Important

Only A and B components with the same batch number may be processed together!

 

  • Surface preparation

All surfaces must be clean and free of contaminants that will inhibit the cure of ELASTOSIL® Sub C 2002 A/B. 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.

 

  • Mixing

Component A of ELASTOSIL® Sub C 2002 A/B contains the platinum catalyst, component B the crosslinker. Even traces of the platinum catalyst may cause gelling of the component containing the crosslinker. Therefore tools (spatula, stirrers, etc.) used for handling the platinum-containing component or the catalyzed compound must not come into contact with this component. The two components should be thoroughly mixed at a 10 : 1 ratio by weight or volume.

To eliminate any air eventually introduced during mixing, the A/B mix can be deaerated under vacuum prior use (25 - 50 mbar, 10 - 15 min). For processing ELASTOSIL® Sub C 2002 A/B in industrial scale, the use of automatic mixing and dispensing equipment is recommended.

 

  • Curing

The curing time of addition-curing silicone rubber is highly dependent on temperature, size and heat sink properties of the components being potted or bonded.

The reactivity can be adjusted within wide limits by adding Catalyst EP or Inhibitor PT 88 to suit the processing requirements of the particular application. 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. Further information is given in our leaflet “Catalyst EP/Inhibitor PT88”.

After completion of the vulcanization process the product may be exposed continuously and without damage to marine or subsea conditions, UV radiation, temperature levels as high as 150 °C (302 °F) and isostatic water pressure of up to 200 bar.

We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions are given in our leaflet "Processing RTV-2 Silicone Rubber". Bonding To achieve a good bonding of ELASTOSIL® Sub C 2002 A/B to sector-specific substrates, it is recommended to use a primer of the WACKER® Primer G series.

 

  • Cleaning

If removal of silicone rubber from machines or dispensing equipment is necessary, white spirit or similar non-polar solvents are recommended. However, cleaning ideally should take place before the rubber is fully vulcanized. Cured silicone rubber can be removed by mechanical means, preferably in combination with a swelling agent (solvent).

储存

The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
