Techsil® RTV27844 is a clear liquid, which cures
at room temperature to a high strength silicone
rubber with the addition of a curing agent.
Once cured, RTV27844 has a hardness
of 44 shore A, with 120% elongation, and a
1,406 refractive index.
RTV27844 is supplied with a curing agent in
matched kits which are designed for use at a
convenient 10:1 ratio by weight. This kit
comprises of 454gm A and 45gm B.
RTV27844 is a low
viscosity, easily pourable liquid with the
capability of remaining flexible at low
temperatures and have been used for the
protection of electronic components and
assemblies against shock, vibration,
moisture, ozone, dust, chemicals, and other
environmental hazards by potting or
encapsulation for applications such as potting
solar cells for maximum light transmission and
electronic assemblies where component
identification is necessary or desirable.
The clarity of RTV27844 allows for visual
inspection through the silicone, permitting
easy identification and repair of the encapsulated
parts. The cure
rate of Techsil® RTV27844 can be accelerated by
heat and it will cure in deep sections or enclosed
assemblies without exotherm and with low
shrinkage. The chemical composition contains
no solvents for ease of use on production lines
and its clarity permits visual inspection for easy
identification and repair of encapsulated parts.
Techsil® RTV 27844 retains its elastomeric
properties at temperatures of up to
