c. Operation 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 molding silicone rubber –
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.
