Sulfur Capping Compound Features

Accurate reporting of the compressive strength of your concrete samples is crucial. Sulfur Capping Compound allows for consistent and accurate results and provides a clear distinct break plane. Please see our product features below.

Quality of Manufacturing

Ultra-thin flakes are carefully manufactured to the highest standards to provide consistency and high strength from cap to cap and bag to bag.

High Compressive Strength

Compressive strength exceeds 8,000psi at two hours per ASTM C617 tests of 2-inch cubes.

High Bond Strength

Bond strength is greater than 150psi. Strength and bond properties of capped specimens does not degrade over time, even when stored in humid conditions.

Fast Melting

Melts quickly at 230°—240°F (110°—115°C) and with reduced odor

Lower Optimum Pouring Temperature

Lower and wider optimum pouring range of 265°—290°F (129°—143°C).

Rapid Setting

Set time is about one minute, and shrinkage is minimal.

Easy to Handle

Flakes are easily and conveniently scooped or poured into hot melting pot. Additional flakes can be added during the workday to maintain adequate quantity of melted capping compound.

Even Load Distribution

Ultra-thin flakes are carefully plasticized to ensures even load distribution during concrete strength testing with no deformation.

Reusable

If accidental overheating occurs, the compound remains usable after cooling, and solidified material can be re-melted with no loss of properties

Standard Requirement

Meets or exceeds ASTM C617

Packaging

Bags are 50 pounds each. Pallet quantity volume discounts available.
