Capping Compound

ASTM C 617

Capping Compounds are specially formulated powders. They are melted and then formed over the ends of the test cylinders to provide a smooth and level surface. Melting point is 240°F (115°C), best flow at 260-280°F (126-137°C)

Made in two formulations with two hour setting time compressive strengths of:

• 5500 psi (38 MPa) Capping Compound Powder
• 8000 psi (55 MPa) High Strength Compound Chips

As an alternative, see capping pad systems
