AP 280 is a two-component kit comprised of a silicone resin with a select grade of aluminum powder packaged separately. Once thoroughly mixed and applied to the substrate, the compound will thicken to a putty-like consistency that will exhibit a high degree of flexibility and adhesion, while functioning as an excellent heat sink for this intended application.

Application:
AP 280, listed on the QPL DPM 5979, was formulated specifically for use when changing the static port heater element on DC-9 and MD-80 powerplants. The non-curing pressure sensitive putty/aluminum mix should be spatula applied at approximately 15 mils thick, allowed to stand for 1 - 2 hours to gain tack, and then manipulated to lay the heater element into the putty compound.

Features:
AP 280 will maintain an excellent bond while exhibiting vibration resistance and flexibility over a very broad temperature range of -100°F to 550°F in continuous service. The kit is pre-ratioed and both components should be mixed completely just prior to application.

Physical Properties:
  • Shelf Life: The Un-mixed kit has a 6 month shelf life from date of packaging
  • Solids: 52% prior to mixing
  • Viscosity (cps): 5500 prior to mixing
  • Service Temperature: -100F to 550F continuous
  • Dielectric Strength: 900 v/mil
  • Dielectric Constant: 2.95@100 Hz, 2.90@ 100,000 Hz
  • Dissipation Factor: 0.004@ 100 Hz, 0.003@ 100,000 Hz
