MasterSil 980 from Master Bond (Hackensack, NJ) is a two part fluorosilicone system for high performance bonding, sealing, coating and potting applications. It withstands harsh chemicals such as gasoline, diesel fuel, motor oil, ethanol and many solvents. After testing, chemical resistance for MasterSil 980 was far superior when compared to standard type silicone systems. Features include:
- An elongation of 100-200% at 75°F, providing enhanced flexibility while maintaining resistance to aggressive thermal cycling and mechanical shock.
- A wide service temperature range from -85°F to +465°F.
- The ability to bond well to a wide variety of substrates including metals, composites, ceramics, glass, rubbers, plastics as well as other silicones.
- An electrically insulative formulation, with a dielectric constant of 6.4 (measured at 75°F, 60Hz) and a volume resistivity of more than 1014 ohm-cm.
Upon mixing, MasterSil 980 yields a moderate viscosity with good flow and a user-friendly open time of 6-9 hours at room temperature for a 50 gram batch.
