Applications
|
Sealing & Adhesion |
|
|
Silicones are used in a wide array of applications for bonding
components, and sealing
against
moisture or
environmental
contaminants. A comprehensive portfolio of 1 Part and 2 Part
Adhesives and Sealants, many of which are excellent candidates for
assembly applications on or near sensitive electrical and electronic
components, are available. These materials are applied by a variety of
methods ranging from manual dispensing to auto-dispensing
units for
tube, cartridge, pail, or drum packages. Mixing for 2 Part grades may be
accomplished by either manual
processes or meter mix dispensing, depending on production volume and
post-mix material properties.

|
Coating |
|
|
The Coating process involves the
application of silicone in a thin
protective layer to a component
surface by methods such as dip,
flow, spray, and selective
robotic coating. Sealection
of a
silicone coating material for a
particular application involves the
consideration of various performance and processing criteria.

 |
|
Potting & Encapsulation |
|
|
 Silicone rubber and
gels are widely used in electronics to ensure
mechanical and environmental protection. A full range of
products are offered in various cure speeds, viscosities, and performance, many of which offer enhancements for thermal cycling
protection, stress relief, material
strength, flame
retardancy, or optical clarity.
