After addition of a catalyst CA-35
RTV M 418                100Parts
Catalyst CA-35               4-5Part
Pot life of the catalyed mix(25, approx) 60minutes
Demould time (25, approx) 8hours

IMPORTANT: If there is any question about the effectiveness of products agent combination, a small-scale test should be made on an identical surface for trial. Increase catalyst will caused cured rubber become crispy.
Measuring and Pouring Performance
Get an accurate scale (gram scale) to weigh Parts A and B. After mixing parts A and B, vacuum degassing is recommended to eliminate any entrapped air. Let mixed rubber seek its level up and over the model. A uniform flow will help minimize entrapped air.

Any question ,please feel free to contact MS Betty zhou
