Super-strength gypsum cement recommended where extreme accuracy and greater surface hardness are required, as in duplicator models. Harder and stronger than HYDROCAL A-11 and HYDROCAL B-11 cements, ULTRACAL 60 cement is similar in all respects to ULTRACAL 30 cement except that it sets in about one hour. Designed for very large models where additional working time and highest possible degree of accuracy are required. |
