DESCRIPTION - FRITZ FR-2 is a free flowing non-lignosulfonate polymer
used to control the thickening time of a cement slurry.

ADVANTAGES

• It may be used to control the setting of a slurry for bottom hole circulating
temperatures up to 250?F. (121 C)
• In a cement slurry, FR-2 does not cause a dispersing effect on the system.

APPLICATION
• FR-2 may be used for retarding any API class of cement (A, C, G or H).
• It may be used with other cement additives such as fluid loss additives, silica flour,
dispersants, defoamers and weighting materials.

PROPERTIES
• White Crystals – readily soluble in water
• Specific Gravity – 1.60
• Bulk Density – 54 lb./gal.
• pH – 3
• Packaged in 50 lb. bags
• Loading Rate – 0.1 to 2.0% bwc
