P-78 high-heat polyester filler and fairing compound offers the user a smooth workable paste with a 40 to 50 minute work life for larger fairing and repair jobs. This material can be applied with a squeegee, spatula, or flat tool, and once cured can be filed or sanded to a feather-edge. P-78 can withstand temperatures up to 446°F to eliminate the “print-through” that is associated with conventional polyester fillers. P-78 has excellent adhesive and bond strength to fiberglass, SMC, FRP, epoxy, graphite, and Kevlar® composites as well as aluminum, wood, and other substrates. Once cured this material accepts virtually all types of coatings and decorative films with no “bleed out”.
Features:
- Two component vinyl ester, sandable thixotropic paste
- 40-50 Minute Work Life
- White
All the same great handling and physical characteristics of our P-77 High Heat Resistant Filler/Fairing Compound but with a longer work life and a much lower density, making it the material of choice in many marine and aircraft applications. Its long work life and high heat resistance make it ideal for a wide variety of applications.
Applications: Ideal for use in filling and fairing large FRP composite surfaces.
