SEMICOSIL® 912

SEMICOSIL® 912 is a pourable, addition-curing, 2-part silicone rubber that cures to a soft silicone gel when mixed with ELASTOSIL® CAT PT, ELASTOSIL® CAT PT-F or ELASTOSIL® CAT UV.



特性

  •  two-part, 10 : 1 mixing ratio
  •  low viscosity
  •  modular system allows flexible adjustment of pot life and curing time by selection among different catalysts (no lot binding between base and catalyst)
  •  fast curing at room temperature with Catalyst PT-F
  •  long pot life at room temperature with Catalyst PT
  •  extremely fast curing with Catalyst UV
  •  low hardness
  •  excellent tackiness

数据表

Encapsulation of electronic components for the automotive and power electronics industries.

Surface preparation
All surfaces must be clean and free of contaminants that will inhibit the cure of the product. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds.

Mixing
The product contains the crosslinker, ELASTOSIL® CAT PT, PT-F or UV contains the catalyst. Even traces of catalyst may cause gelling of the component containing the crosslinker. Therefore tools (spatula, stirrers, etc.) used for handling the catalyst-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 introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended.

Curing
For curing an oven at elevated temperatures can be used.

Oven temperature                      Curing time
100°C                                         2 mm

Catalyst PT                                30 min
Catalyst PT-F                             10 min
Catalyst UV                                2 min
# UV dose 1.5 J/cm2, 250-350nm

The system is activated by direct UV irradiation. UV-irradiation should use emissions in the wavelength range between 250 and 350 nm.
Typically D-bulbs (Fe-doped, Hg-light sources) using ozone-free quartz should be used and are commercially available (see figure 2). H-bulbs with emissions below 250 nm are not recommended.

Curing time of the UV-active system is highly dependent both on the intensity and dose of the UV-light and the spectral intensity distribution. The curing is also dependent on the layer thickness, the optical properties of the substrate and temperature. Increase of the temperature will fasten curing reaction.

储存

SEMICOSIL® 912 should be stored dry and cool in the tightly closed original container.

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.
