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.
