Operations for RTV 2 silicone rubber:
Step One to use RTV 2 silicone rubber: Take 100g of part A and add 2g of part B and mix the silicon rubber and the curing agent evenly.
Step Two to use RTV 2 silicone rubber: vacuum pumping
Without exception, this takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
Step Three to use RTV 2 silicone rubber: Brushing cast & Perfusion Molding operation.
Frequently asked questions of RTV-2 silicone rubber for mold making
Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine ***ailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take th |
