Several different curing agents are available for two-component RTV silicone rubber compounds to provide a choice of cure speed, mixing ratio, or deep section cure. Momentive's RTV9910 is one such curing agent. This silicone paste has a beige appearance and like other curing agents (DBT, STO, and RTV9950), it is based on metal soaps. Additionally, this item works best by working with others, particularly with the following Momentive Performance Materials products: RTV11, RTV21, RTV31, RTV41, RTV60, RTV88, RTV511, RTV560, and RTV577.
