 Si
Prime™ is a coating system specifically designed
for bonding silicone rubber to a variety of different surfaces
with common acrylic adhesives used in the membrane switch industry.
Si Prime™ offers the best solution to the
intrinsic problem of bonding rubber to polyester switches for
far less cost than mechanical means. A thin coating of Si
Prime™ is added to the underside of a Silastikey
silicone rubber array.
This coating serves as a bonding barrier
between the silicone surface and an acrylic adhesive. When used
in conjunction with any 3M™ 350 series
Hi holding acrylic adhesive, Si Prime™ offers an outstanding high bond strength for elastomer keypad
applications. Under independent lab test using ASTM standard D-3330,
Si Prime™ outperformed by more than two times the
bonding capabilities of other silicone/acrylic adhesives.
