Gray Iron 9000 Sulfur Capping Compound (50LB Bag)

Gray Iron 9000 Sulfur Capping Compound (50LB Bag)

• Reliable sulfur mortar capping compound offers faster melting times and lower optimum pour temperature.
• Ultra-thin flakes melt quickly at 230°F to 240°F (110°C to 115°C) with reduced odor.
• Compound is not damaged by overheating and can be re-melted with no loss of properties.
• ASTM C617 compliant. Meets ASTM C287, ASTM C617 standards.

Iron 9000 is a new and improved sulfur mortar capping compound that ensures even load distribution during concrete strength testing. Ultra-thin, low-odor flakes are carefully formulated from sulfur and mineral filler. Gray Iron melts quickly at 230°F to 240°F (110°C to 115°C), with a wide optimum pouring range of 265°F to 290°F (129°C to 143°C). Set time is about one minute, and shrinkage is minimal. If accidental overheating occurs, the compound remains usable after cooling, and solidified material can be re-melted with no loss of properties. Compressive strength exceeds 8,000psi at two hours for ASTM C617 tests of 2in cubes, and bond strength is 150psi or more. Strength and bond properties of capped specimens does not degrade over time, even when stored in humid conditions.
