Summary 1. CH210L Mid Temperature Retarder can extend and adjust cement slurry's thickening time. 2. CH210L Mid Temperature Retarder is suitable for moderate temperature system. 3. CH210L Mid Temperature Retarder can only be used by water mixed and has no special r- equirement for water quality, which can be applied in brine system. Special Attentions 1. CH210L Mid Temperature Retarder maybe influenced the top strength of set cement when the curing temperature is lower than the bottom hole cycle temperature. 2. When the bottom hole cycle temperature is higher than 100C, the dosage of CH210L Mid Temperature Retarder will be significantly increased and the top strength may be influenced. Applications Temperature: Normally 131-203°F (55-95°C) (BHCT). Dosage: CH210L Mid Temperature Retarder generally 0.2-3.0% (BWOC).
