Description
3M 7961 MP Membrane Switch Spacer – double-coated sheets
3M 7961 MP is a dry acrylic adhesive 200MP formed as sheets with dimensions of 61cm (width)/ 91.4cm (height). Bond to high surface energy materials and provides long-term durability for bonded metals, plastics, polyester, glass, polycarbonate, ABS and so on. 3M double-sided adhesive sheets have no expansion during temperature changes. 3M Membrane Spacer 7961 MP is designed for manufacturing of flexible tactile keyboards and electronic displays. It is because 3M 7956MP has a fixed adhesive thickness.
Double-sided sheets 7961 MP have a polyester film carrier that is excellent dielectric. It is moisture resistant so no folds are guaranteed. They are perfect for bonding electronic displays and mobile phone displays.
Using 3M double-sided sheets (membrane switch spacers), you can quickly make each product become self-adhesive. It is very convenient for customers. The thickness of bonding across the whole width of the materials is guaranteed. Thus the products do not change their appearance and their bond strength.
Bonds a wide range of materials:
- plastics
- glass
- metal
- wood
- polyester
- ABS
- polycarbonate
- others
Advantages:
- Pressure resistance
- High temperature resistance
- UV resistance
- Does not fold from water
- Clear adhesive with no impurities
- Solvent resistance
- Used as a dielectric
Bonding technique:
Before bonding use isopropyl alcohol mixture to clean the surfaces. After that let them to dry out. Bond at temperatures in range of 21°C to 38°C to have good adhesion. It is not recommended to bond at temperatures under 10°C. When you work with chemicals, take precautions.
