Curing inhibitation of silicone rubber
You can use Shin-Etsu KE1314 Silicone rubber www.shinetsu.co.jp , this type of silicone rubber is no good in doing Optical clear transparent PU castings. Or you can either place the masters in 60°C oven for 1 hour or in room temperature for 3 days to decrease the inhibitation.

Is anyone using SL5220 and/or SL5240 resins as masters for RTV urethane
castings? I believe I'm having contamination problems with my silicone from the
sla material (master) and would like to receive feedback from people that have
had similar issues. I would like to speak with actual users and not vendors
wanting me to use their products. Thanks for any helpful info.
