A high temperature cement retarder with mild dispersing characteristics. The thermally
stable organic-type blend is designed to perform efficiently in intermediate to high
temperature ranges when used individually. Additionally, VC-R2 is especially effective for
ultra-high temperature ranges when used in combination with co-retarder VC-RE3. In
application, VC-R2 successfully performed in slurries with temperatures of over 300°F
(150°C) when used individually. When combined with VC-RE3, the retarder blend
performance was tested well over 400°F (+200°C). The retarder and co-retarder are well
suited for all API classes of cements.
