Silicone Adhesives & Sealants
For high performance
Fixing components and sealing of housings
BECTRON® SA 70.. silicone adhesives and sealants offer excellent unprimed adhesion for fixing
components and lid sealing applications. They show excellent adhesion to most substrates
used in the electronics industry such as FR4, PBT, aluminium, copper and many other common
materials. Thanks to their low modulus, they are often used to seal gaps between materials
with very different coefficient of thermal expansion, remaining flexible over a wide range of
temperatures.
Heat dissipation
BECTRON® STC 74P1-51 is a thermally conductive compound for powerful components,
which delivers high thermal conductivity at thin bond line.
BECTRON® SA 75L7-70 is our thermally conductive adhesive for more stringent needs and
offers a good combination of high thermal conductivity, excellent adhesion and strong
dielectric properties.
