Long term, environmentally stable adhesive to resist UV. light, chemicals, and temperatures to 300F (149C). actuation. Add a different thickness of adhesive to one side of a membrane switch to build a membrane switch spacer. Designed for use as a substrate for membrane switch circuitry. Hold metal domes in place. Protect conductive leads. Applications High cohesive strength of the adhesive withstands repeated stresses of switch Features: 90 Bleached Kraft Adhesive Not for specification purposes Carrier Physical Properties 1.0 Polyester November 1994 Supersedes Updated Product Data Sheet Single Side Membrane Switch Spacer 7993MP Scotch2 Date : Single Side Membrane Switch Dynamic Peel - 180 Peel Initial Adhesion Stainless Steel N/10mm 3.6 Temperature Range Low : -40F (-40C) High Long Term (days/weeks) : 250F (121C). High Short Term (minutes/hours) : 300F (149C). Chemical Resistance properly applied to impervious materials. The adhesive resists softening through edge contact with mild acids, alkalis, oil, gasoline, Kerosene, JP-4 fuel and many other solvents. Not recommended for total immersion. Moisture & Humidity Relative Humidity at 38C. The bond strength of Scotch 200 Hi-Performance Acrylic adhesive increases as a function of time and exposed to air or sunlight (U.V.). Die-cutting: Roll Laminating: Use rubber over steel roll set up with firm application pressure. Make adhesive to substrate contact at nip area only to exclude air entrapment. Steel rule or punch press die-cuttable. Processing Adhesive is very resistant to oxidisation and ozone when U.V. Resistance temperature. Bond Build Up Resistance No adverse effect on the bond after exposure to 100% Solvent resistance is excellent when this product is Not for specification purposes Performance Properties and Not for specification purposes (ASTM D-3330, PSTC3) Spacer 7993MP July 2000
