After addition of a catalyst

RTV M 418                                                    100Parts

Catalyst CA-22                                            2.5Part

Pot life of the catalyzed mix (25°C, approx)   25minutes

Detmold time           (25°C, approx)   4 hours

After addition of a catalyst CA-35

RTV M 418                                                    100Parts

Catalyst CA-35                                            4-5Part

Pot life of the catalyzed mix (25°C, approx)    60minutes

Detmold time           (25°C, 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.
