“RS3A mold release works very well and is very durable for release of silicone, there is no sign of release transfer to the molded product or any surface change which is common with other mold releases. There is no touch-up needed for a good release. After four hours of running there was no noticeable change in release and believe it was not necessary for touch-up.”
