ELASTOSIL® E50 N TRANSPARENT

ELASTOSIL® E50 N TRANSPARENT is a flowable one-part silicone rubber for potting, coating or sealing applications. When exposed to air moisture it cures at room temperature to yield a permanently flexible silicone rubber with very good mechanical properties.

 

Fully vulcanized ELASTOSIL® E50 N TRANSPARENT shows long-term stability against weathering, moisture and UV radiation. The silicone elastomer may continously be exposed to constantly changing climatic conditions, UV radiation and temperature as high as 180 °C (356 °F) without damage.



特性

Uncured:

  • Flowable
  • Fast skin formation at room temperature
  • By-product of curing: acetic acid

 

Cured:

  • Medium hardness
  • Recommended service temperature range:
    -50 °C to +180 °C

Please note: fully cured ELASTOSIL® E50 N TRANSPARENT is suitable for uses under the Recommendation "XV. Silicones" of the BfR and 21 CFR § 175.300 "Resinous and polymeric coatings" and FDA 21 CFR §177.2600 "Rubber articles intended for repeated use", provided that any given limitations on extractable and volatile substances are observed. Residual solvents have to be completely removed from the food contact article.

ELASTOSIL® E50 N TRANSPARENT is a ready-to-use, one-part silicone rubber which starts curing when exposed to air moisture. Typical curing characteristics are given in the table "Properties Uncured".

 

As RTV-1 silicones require humidity for curing, free access of air moisture to the silicone rubber is essential. Additionally, the vulcanization time of ELASTOSIL® E50 N TRANSPARENT can be greatly reduced by increasing the level of air's relative humidity. Please note that, unlike the initial skin formation, the total curing rate of RTV-1 silicones is limited by moisture's diffusion speed in silicone rubber.

 

As increasing the curing temperature has just a minor effect both on the skin forming time and the curing speed, ELASTOSIL® E50 N TRANSPARENT typically is vulcanized at room temperature. Heat curing is recommended only for applications where the silicone rubber is applied as a thin film (thickness less than 0.5 mm), because otherwise blistering is likely to occur due to the quick release of acetic acid.

 

After completion of the vulcanization the silicone elastomer may continuously be exposed to constantly changing climatic conditions, UV radiation and high temperature without damage. Cured ELASTOSIL® E50 N TRANSPARENT usually shows good primerless adhesion to many substrates, e.g. glass, ceramics, metals, plastics and powder coatings.

 

Detailed information about the processing of RTV-1 silicones is given in our brochure “ROOM TEMPERATURE VULCANIZING (RTV) SILICONES - MATERIAL AND PROCESSING GUIDELINES”. We recommend running preliminary tests to optimize conditions for the particular application.

 

Removal:

If removal of the silicone from machines or dispensing equipment is necessary, white spirit or similar nonpolar solvents are recommended. However, cleaning ideally should take place before the silicone rubber is fully vulcanized. Cured silicone needs to be rubbed off or removed mechanically, if necessary in combination with a swelling agent (solvent) or a chemical silicone remover.

储存

Store in a dry and cool place.

 

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.
