DURAMAX™ B-1022 Ceramic Binder Description DURAMAX B-1022 ceramic binder is an aqueous emulsion for enhancing green strength of industrial ceramic parts. DURAMAX B-1022 ceramic binder is provided as a ready-to-use water-based emulsion, with no dissolution required. Due to its low viscosity relative to other binders, DURAMAX B-1022 ceramic binder can be used to prepare slurries at higher powder loadings. Unlike other water-based binders, spray-dried powders incorporating DURAMAX B-1022 ceramic binder in their composition are highly insensitive to changes in humidity. Scrap containing DURAMAX B-1022 ceramic binder can be reslurried and reused. *Note: Rohm and Haas does not sell or intend for these products to be used in applications involving ceramic parts for bone replacement.

Typical Use Procedure Mill ceramic powder, water, and dispersant* to deagglomerate powder. Add DURAMAX B-1022 ceramic binder and stir to mix. Avoid or minimize milling the binder; this can degrade performance. The preferred large-scale mixing method is paddle agitation at 50-150 rpm. DURAMAX B-1022 ceramic binder is supplied pre-dispersed in water at 45% solids. The recommended use level is 0.5-5% dry weight based on powder. If reducing the hardness of DURAMAX B-1022 is desired, blend it with lower Tg, DURAMAX B-1000 ceramic binder. Example: 100 g of Alcoa A-16SG alumina, 53.0 g deionized water and 0.86 g of DURAMAX D-3005 solution (35% solids, 0.3% on alumina, solids basis) were charged to a 000 ball mill half filled with alumina grinding cylinders. The mixture was tumbled for 40 minutes and decanted. 6.67 g of DURAMAX B-1022 ceramic binder (45% solids, 3% on alumina, solids basis) was added, the mixture was stirred 10 minutes to mix, then spray dried. Reslurry Procedure Mill scrap with water, and adjust pH to above 9 (i.e., 9.5) using aqueous ammonia. Mill to deagglomerate. Check particle size of the slurry to monitor process efficiency. Once the scrap is reslurried, then spray dry. Strength may drop slightly upon reslurry; this can be corrected by adding 0.5-1.0% DURAMAX B-1022 ceramic binder (solids basis) or blending with fresh slurry. DURAMAX D-3005 Dispersant is a very effective product for deagglomerating most ceramic powders.
Material Safety Data Sheets Rohm and Haas Company maintains Material Safety Data Sheets (MSDS) on all of its products. These contain important information that you may need to protect your employees and customers against any known health and safety hazards associated with our products. We recommend you obtain copies of MSDS for our products from your local Rohm and Haas technical representative or the Rohm and Haas Company.
