Note: This is a 100A:3B mix ratio product that must be measured by weight. The
choosing of suitable hardness should be according to the size and pattern
design of
the products. If large products and therefore multiple-piece molds are needed
by
customers, silicone rubber with higher hardness will be required for the molds.
Conversely, soft silicon is indispensable for molds with complicated pattern
and
delicate details. The amount of curing agent admixture depends on the actual
need
of customers. More will be added for speedy drying and fast release and less
when
otherwise.
Guochuang Silicone manufacture and produce custom rtc-2 silicone, addition cure
silicone rubber, silicone for mold making. Our platinum cure silicone rubber,
liquid silicone rubber for sale.
