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

How to prevent silicone manual
molds getting sticky?
The main reason for this problem is
that you do not handle the products or original molds well, then
you should deal with the original mold or products carefully before
molding. Such as for the products with a complicated pattern or a
unsmoothed surface, you should polish and clean the products after
which it will be molded ,then spray the release agent. Normally,
the release agent can be Vaseline , detergent. liquid wax Etc. In
practical process, you can bush different release agent according
to different material.
The second reason is that the
operator pour the silicone into the mold when the mixture is mixed
evenly, then the finish silicone mold will not cure and dry
entirely.
