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.
Architectural reproduction and restoration specialists use GC liquid mold
silicone
rubbers to make site molds of aging/damaged ornate architectural elements. We
are
China architectural molding silicone, architectural restoration molding
silicone
supplier and exporter.
