| Q. |
What
temperature must sulfur products be heated to melt and use? |
| A. |
Sulfur
products should be heated to a temperature between 275°F (135°C)
to 295°F (146°C). It is important to understand that sulfur
products go through a viscosity minimum in this temperature
range. The ideal temperature range for minimum viscosity is
280°F (138°C) to 285°F (141°C). Users should avoid the temptation
to increase the temperature above this range to reduce viscosity,
as the viscosity will increase as the temperature increases
above 285°F (141°C). |

|
| Q. |
My
sulfur was overheated. What should I do with it? |
| A. |
Sulfur
that has been accidentally overheated to a temperature in
excess of 320°F (160°C) should be cooled, solidified and discarded
according to all applicable local, state, provincial and federal
environmental regulations. |
| |
|
| Q. |
What
is the highest temperature that I can use the solidified sulfur
at after it is poured in place? |
| A. |
In practice,
sulfur mortars have a maximum continuous use temperature of
190°F (88°C). Above this temperature, they undergo a phase
change that will weaken the product. |
| |
|
| Q. |
What
type of apparatus is needed to heat sulfur to a molten state
for use? |
| A. |
Ingots
should be broken up and placed in a thermostatically controlled
electrical melting pot, such as a home appliance cooker-fryer
or oven unit or a cast iron roofer's or plumber's pot. Sta-Warm
Electric Company, 553 North Chestnut Street, Ravenna, OH,
also produces various types and sizes of melting pots. |

|
| Q. |
What
effect do plasticizers have in sulfur? |
| A. |
Plasticizers
help to increase the toughness and ductility of the sulfur
compound. |
| |
|
| Q. |
Do
I need to use a respirator when using sulfur products? |
| A. |
When
melted, sulfur gives off the odor of rotten eggs, which is
hydrogen sulfide. It can be an annoying odor at very minimal
concentrations in air. Ventilating the space for employee
comfort should keep the concentration of hydrogen sulfide
below the exposure limit. For exact information, air sampling
is recommended. |

| Q. |
How
do I get an MSDS for Atlas sulfur cements? |
| A. |
Contact
us at msds@atlasmin.com
and provide us with the complete product name and a fax number. |
| |
|
| Q. |
What
is the smallest size orifice that Atlas sulfur products will
flow through? |
| A. |
Atlas
sulfur products will flow through openings that are approximately
3/16" (4.8 mm.) to 1/4" (6.4 mm.). |
| |
|
| Q. |
How
quickly does the material cool? |
| A. |
This
varies with the quantity of material poured. The surface,
however, will cool immediately to a dull finish. |
