 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.
Si Prime offers:
- Field proven (More than million units and different applications)
- Highest silicone rubber to surface bonding
- Bonding strength increase with time
- Excellent resistance to slippage or flagging
- Operating temperature tested to -40°C to 85°C
- High humidity resistance
- Good solvent resistance
- Shelf life two years +
