Condensation Liquid Silicone Moulding Rubber Plaster Mold Making
Silicone
MCSIL-920 RTV2 silicone rubber is a kind of two-component material,
that is the mold making silicone rubber made up of Part A base
silicone and Part B curing agent. The mixed Part A base silicone
and Part B curing agent can cure at room temperature by a
condensation reaction,then become a silicone rubber mold that can
be used for objects reproduction.
Advantages of MCSIL-9 series RTV2 silicone liquid rubber:
-Amazing fluidity and easy to operate (10000~13000 Cps)
-Complex design available
-Not Oily ,Stable quality, odorless catalyst provided
-Excellent tension and tear strength
-High performance in duplication
-Shrinkage is almost zero (below 0.2)
Applications of MCSIL-9 series RTV2 silicone liquid rubber:
Tin cured silicone can be used for casting polyurethane, epoxy,
polyester resin, PU resin, cement, plaster, gypsum, candle,soap,waxes, toys crafts, poly resin crafts, Lighting, plastic toys,
stationery gifts, statue,furniture decorative materials, building
decoration material, sculpture, sandstone, low melt alloys/metals,
urethane and so on.
USING INSTRUCTION of MCSIL-9 series RTV2 silicone liquid rubber:
1- Take 100g of part A and add 2g of part B and mix the silicone
rubber and curing agent evenly.
2- vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise,
it will cause , and no more further steps will be available
3- Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and
evenly pour into the mixed silicon rubber into the square frame.
After the cross linking reaction.
Package of MCSIL-9 series RTV2 silicone liquid rubber:
Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
Storage
When the silicone rubber is stored at or below 30 centi degree in
the original unopened containers, Silicone Base and Curing agent
have a usable life of 12 months from the date of production. After
12 months stockpiles use the Stir to mix the Part A silicone for
some minutes, then the silicone can be use again, no influence for
other performance.
