Flake-Style sulfur capping compound for testing of concrete cylinders, concrete blocks, concrete prisms, and other special shapes for compressive strength.
High compressive strength, exceeding ASTM C-617 standard!
Superior bond strength to concrete, less rejects!
No free-silica dust, it's safer to work with and it has less odor!
Thin Flake style, it melts down faster and it's easier to work with!
Low odor, the key is to lower the temperature!
Consistent from batch to batch and it's reusable!
Less costly and more accurate than rubber caps!
Silica-filled.
Melting range of 265° to 290°F (130° to 143°C)
Compressive strength is 8000 to 9000 psi on 2" cube.
