Set Retarding and Water Reducing

EUCON RETARDER 75 is a synthetically produced liquid water-reducing and set retarding admixture for concrete. It is a modified organic polymer of sodium gluconate. EUCON RETARDER 75 does not contain calcium chloride or other potential corroding materials, and may be used in the presence of aluminum or zinc metals. It is compatible with air-entraining agents, waterproofers and calcium chloride, but they must be added separately to the mix.
