Material description
The removable sealing compound PH-S-607 is a addition
curing two-component silicone rubber that vulcanizes at
room temperatures.
It has a excellent flowability with good self-deaeration. The
compound has good dielectric properties. The compound
can be removed by knife or similar tools.
Application
Encapsulation of electrical and electronic components.
Processing
Before the rubber base is taken from the drum or mixed
with the catalyst, it must be stirred thoroughly, preferably
using a mechanical stirrer, in order to redisperse any filler
which may have settled.
For processing Silicon E the hardener must be filled in
the rubber base and both components must be mixed
with constant stirring.
The mixture should be poured in a thin stream from close
as possible. The point of contact should not be varied
once selected. The silicone rubber will thus fill all voids
and expel air. The resultant vulcanisates are bubble-free.
PH-S-607 will cure at room temperature as well as at
elevated temperature.

PH-S-607 does not adhere to other substrates. If the
adhesion of the rubber to different metals or glass is
required, the application of a primer is necessary. To
achieve an optimal adhesion it is advisable to cure the
compound at elevated temperatures (for example 1 hour
at 150°C).
Certain chemicals can retard, or in unfavourable cases,
prevent the vulcanistion. This includes sulfar-, tin-,
nitrogen-compounds like amines, amides, azides, some
antioxidatants in plastic and rubber, certain plasticine
types, residues of solid condensation curing silicone
rubbers, phenol resins, etc. The user is advised to test
all raw materials as to their compatibility with PH-S-607.
Storage
The original closed tins have to be stored in a dry and
frost-free place. Open units must be used at once.
The processing-guarantee is 12 months after production
date (see labels on the containers).
Hazardous / Safety advice
Follow the advice printed on the containers and the
relevant safety data sheets for resin and hardener. |
