High-temp RetarderC-H410L

Description

• C-H410L include C-H410L（standard type）and C-H410L-W（freeze proof type）。
• C-H410L polymer type retarder，a larger temp range, can extend viscosity time of cement slurry in high temperature, with strong regulative, no special requirement to water condition, preparing slurry with fresh water or salty water can be available.
