Instructions for Manual Molding
Silicone Rubber
RTV*2 Manual Molding Silicone Rubber
is a flowable liquid, and the
quality has nothing to do with the color. It consists of two
component. Part A is a flowable liquid silicone rubber, part B
is the curing agent. Firstly, after your previous work of
dealing with the original model, take some liquid silicone
rubber , add 2%*3% curing agent of the amount of silicon, and
mix them evenly. Then after vacuum-pumping the mixture, you can
pour it into the mold frame. The silicone mold will cured in
**3 hours.
Note:The time for vacuum-pumping should be less
than 3—5 mins ,otherwise, once the silicone rubber has
cross-link reaction during vacuumizing, it will not be
operated.
FAQ of manual
