Liqui-Bond^® SA 1000 (One-Part)
March 2012
PRODUCT DESCRIPTION
Thermally Conductive, One-Part,
Liquid Silicone Adhesive
FEATURES AND BENEFITS
• High thermal performance
• Eliminates need for mechanical fasteners
• Low viscosity for ease of screening
or stenciling
• Can achieve a very thin bond line
• Mechanical and chemical stability
• Maintains structural bond in
severe-environment applications
• Heat cure
Liqui-Bond^® SA 1000 is a thermally
conductive, one-part liquid silicone
adhesive with a low viscosity for easy
screenability. Liqui-Bond^® SA 1000
features a high thermal performance and
maintains it’s structure even in severe
environment applications.
Liqui-Bond^® SA 1000 features excellent
low and high-temperature mechanical
and chemical stability.The material’s
mild elastic properties assist in relieving
CTE stresses during thermal cycling.
Liqui-Bond^® SA 1000 contains no cure
by-products, cures at elevated
temperatures and requires refrigeration
storage at 10°C.The material is
available in both tube and mid-sized
container forms.
