ADVANTAGES
• PCR-3L is a 40% active liquid that is added to the mixing water before slurrying with cement.
• It may be used to control the setting of a slurry for bottom hole circulating temperatures
up to 250?F. (121 C).
• In saturated salt slurries it may be used to 350?F. (177 C)
• In fresh water cementing systems it may be used up to 430?F (221 C) when combined
with Fritz PCR-4, cement retarder intensifier.
• PCR-3L has a retarding and dispersing effect on the cement slurry during placement.

APPLICATION
• PCR-3L 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.
