3M 7995MP Hi-Performance Acrylic 200MP
Categories: Polymer; Adhesive

Material Notes: This adhesive meets the requirements of most long-term applications. It offers temperature resistance to 400°F (204°C). Peel adhesion values are excellent on most membrane switch substrate materials. It features exceptional shear strength and adhesion to high surface energy (HSE) plastics and metal surfaces.

Single side spacers aid in the construction of membrane switch circuiry, i.e. to protect leads, hold domes in place, or build spacers
