Curing Agent Accelerator for Tin-Cure Silicones


Our RTV curing agent accelerator is a clear amber fluid with a mild odor, which is meant for use in tin catalysed silicones only (our products RTV1000 or RTV325). This accelerator has a powerful effect on the curing speed. Small amounts have a dramatic effect. With the slow (BLUE) curing agent, a 1% addition of accelerator produces a 5 minute cure and 0.25% addition will produce a 2 hour cure. 0.25% is equivalent to 3 drops of accelerator per weight ounce, or 1.125 grams per pound of RTV1000 base rubber. The accelerator reduces pot life as well as cure time, so adjust the amount for best results.
