Product Q&A
Q:What is the mixing ratio for Part A and Part B?
A:
The mixing ratio is 100:2 by weight. Part A is the silicone base and Part B is the CA30 curing agent.
Q:How long does it take for the silicone to cure?
A:
The material cures to a flexible rubber within 6 hours at room temperature. We recommend demolding after 24 hours for better replication results.
Q:What is the hardness of the cured silicone?
A:
The hardness of the cured silicone is 28 Shore A.
Q:Can I use vacuum de-airing to remove bubbles?
A:
Yes, it is strongly recommended to use a vacuum chamber to remove entrapped air. The mixture will expand 3-5 times under vacuum.
Q:What are the available packaging options?
