Dual-component filler
Marine P-78 Hi Heat/Long Work Life ADTECH Plastic systems - Cass polymers

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".

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.
