牌号简介	Baydur® GS-772是一种用于反应注射成型（RIM）工艺的固体聚氨酯系统。该系统作为两种反应性液体成分提供。A组分为多量二苯基甲烷二异氰酸酯（PMDI），B组分为配制的多元醇体系。Baydur® GS-772系统用于恶劣环境条件下的应用，如泵壳、集水池和地下设备。在应用要求减轻重量、提高耐腐蚀性和/或提高耐磨性的情况下，也可用作铸铁的替代品。与产品一样，用户必须提前对给定应用中Baydur® GS-772系统的使用进行测试（包括现场测试等），以确定其适用性。 Baydur GS-772 is a solid polyurethane system used in the reaction injection molding (RIM) process. The system is supplied as two reactive liquid components. Component A is a polymetric diphenylmethane diisocyanate (PMDI) and component B is a formulated polyol system. Baydur GS-772 system is used in applications where harsh environmental conditions are encountered, such as pump housings, catch basins, and underground equipment. It is also used as a replacement for cast iron where the application requires weight reduction, improved corrosion resistance, and/or improved abrasion resistance. As with and product, use of the Baydur GS-772 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.	Baydul- 661 IBS是一种用于反应注射成型（RIM）工艺的灰色、刚性聚氨酯结构泡沫体系。该系统包括一个专门设计的交互式吹扫系统（IBS），作为两个反应性液体成分提供。A组分为聚合物二苯基甲烷二异氰酸酯（PMDI），B组分为不含CFC-或HCFC发泡添加剂的配方多元醇体系。注意：由于可能存在颜料沉淀，在将桶内物质输送至日计量箱之前，应彻底搅动成分B。Baydur 661 IBS系统用于交通、工业和娱乐市场。这些应用通常利用了材料的强度、优异的表面光洁度和大零件性能。与任何产品一样，在给定应用中使用Baydur 661 IBS系统必须由用户提前进行测试（包括现场测试等），以确定适用性。 Baydur 661 IBS is a gray-pigmented, rigid polyurethane structural foam system used in the reaction injection molding (RIM) process. This system incorporates a specially engineered interactive blowing system (IBS) and is supplied as two reactive liquid components. Component A is a polymeric diphenylmethane diisocyanate (PMDI), and Component B is a formulated polyol system containing no CFC- or HCFC-blowing additives. Note: Component B should be agitated thoroughly prior to delivery of drum contents to day tank due to possible pigment settling. The Baydur 661 IBS system is used in transportation, industrial, and recreational markets. The applications typically take advantage of the material's strength, excellent surface finish, and large-part capability. As with any product, use of the Baydur 661 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
