Firm 40 shore A Platinum Cure RTV2 Silicone RubberMC Silicone addition cure molding silicone rubber is a two
component elastomer cross-linking at room temperature. The
polymerization can be accelerated by heat. The silicone components
are delivered as liquids, which once mixed and cured transform into
a transparent, elastic and resistant material. Polymerization
occurs without formation of heat.Characteristics of Platinum cure Silicone rubber for Molding#Convenient to operate because the RTV property#Easy to mix due to the low viscosity (7000~9000Cps)#High duplication because of high tear and tensile strength#Long shelf life with low shrinkage#Can be accelerated for rapid cure
#Food safe, Non-Toxic, Odor free
#Resistant to high temperature
Applications of Platinum cure Silicone rubber for Molding1.A range of materials can be cast into the cured silicone mold:polyurethane and other reactive resinsSmall pieces of cement,plaster,concrete products.Food like chocolate,fondantsWax,candle,soap;Low melt metal2.casting body parts,shoe insole,cloth label,texture coating.
Instructions for Platinum cure Silicone rubber for Molding1. Preparing
The surface of the original objects should be clean and free of
loose material. If your products have thin flower patterns, and
especially have porous substrates, please use a suitable mold
release agent such as soap water, detergent, Vaseline or petroleum
jelly.
2. Mixing
Please weigh Part A silicone base and part B CA30 Curing Agent with
ratio of 100: 2 into a clean container. Stir Part A base silicone
thoroughly before use, then Mix Part A and Part B evenly until the
curing agent completely dispersed in the silicone base. Manual or
mechanical mixture can be used, but do not last much time or allow
the temperature to exceed 35° C (95° F). It's suitable to mix small
quantities to ensure thorough mixture of silicone base and curing
agent.
Note: It is strongly recommended that entrapped air be removed in a
vacuum chamber, allowing the mixture to completely expand and then
collapse. After a further 1 to 2 minutes under vacuum, the mixture
should be inspected and can be used if free of air bubbles. A
volume increase of 3-5 times will occur on vacuum de-airing the
mixture. So a suitably large container should be chosen.3. Pouring and curing
Pour the mixed Part A base silicone and CA-30 curing agent as soon
as possible onto the original object, avoiding air entrapment. The
catalyzed material will cure to a flexible rubber within 6 hours
(or faster by different mixing ratio or room temperature), we
advice you de-mold after 24 hours, it is will improve the replicate
times of silicone mold.
Storage and shelf lifeWhen the silicone rubber is stored at or below 25 degree Celsius 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, please use tool to stir the Part A silicone for some
minutes, then the silicone can be use again, no influence for other
performance.Package:20kg per drum, 200kg per drum20kg/drum;480kg/pallet or 640kg/pallet.
