Description of Addition cure RTV-2 mold making silicone rubber
Addition cure RTV-2 mold making silicone rubber is generally
namedtwo-components silicone rubber, Part A is a flowable liquid,
part B is thecuring agent. It features an exceptional fluidity and
good operability. Themixing ratio is 1:1, mainly be suitable for
making FDA molds application.
Applications of Addition cure RTV-2 mold making silicone
Addition cure RTV-2 mold making silicone rubber could be
mainly usedfor making concrete stones, precision molds, PU molds,
for life casting, fabricfinishing, seal for electronic components
and solar circuit board, trademarkdecoration. etc.
OPERRATING INSTRUCTION of Addition cure RTV-2 mold makingsilicone
1. Stir part A and part B with right mixing ratio evenly. And get
themixture for vacuum-pumping. (If there is no vacuumizer, you can
just pour themixture slowly from the corner so that less bubbles
2. Enclose the product (the original model) with four plastic
plates orwooden plates.
3. Clean your products and brush a layer of release agent(detergent
orsoap water) on your product.
4. Pour the mixture with correct mixing ratio into the model frame.
After about 2-4 hours, when the silicone cured, get out the
originalmodel, and there you get a finished addition cured silicone
