392°F); no post cure required
Potential Uses
Protection of electrical/electronic devices
Silicones and Electronics
Long-term, reliable protection of sensitive circuits and
components is becoming more important in many of today’s
delicate and demanding electronic applications. Silicones
function as durable dielectric insulation, as barriers against
environmental contaminants and as stress-relieving shock
and vibration absorbers over a wide temperature and
humidity range.
In addition to sustaining their physical and electrical
properties over a broad range of operating conditions,
silicones are resistant to ozone and ultraviolet degradation,
have good chemical stability and are available in a variety of
useful forms as conformal coatings, encapsulants and
adhesives. Dow Corning’s broad range of general purpose
and specialty products offers you a choice of materials for
your application needs.
DESCRIPTION
Dow Corning silicone encapsulants are supplied as two-part
liquid component kits comprised of:
Mix Ratio
Components
(by weight or volume)
(as supplied)
1:1
Part A/Part B
10:1
Base/Curing agent
When liquid components are thoroughly mixed, the mixture
cures to a flexible elastomer, which is suited for the protec-
tion of electrical/electronic applications. Dow Corning
silicone encapsulants cure without exotherm at a constant
rate regardless of sectional thickness or degree of confine-
ment. Dow Corning silicone elastomers require no post cure
and can be placed in service immediately following the
completion of the cure schedule with an operating temper-
ature range of -45 to 200°C (-49 to 392°F). Select materials
have been classified by Underwriters Laboratories and/or
meet military specifications. Standard silicone encapsulants
require a surface treatment with a primer in addition to
good cleaning for adhesion while primerless silicone
encapsulants require only good cleaning.
