1.RTV Silicone,ZA 40 Thixo
ZA 40 THIXO FAST - this is a very solid silicone rubber, which can be applied to the skin to create the shape of the face, hands or other parts of the body. Rubber vulcanised quickly at room temperature and accurately conveys the shape of the body of any initial model - better and faster than with any alginate.
Unlike alginate forms, suitable only for a single use, flexible shell mold of ZA 40 THIXO FAST has been successfully used in multiple fills most complex and exotic products.
For the casting of final products manufactured in the form of ZA 40 THIXO FAST, you can use molding materials based on polyurethane, polyester and epoxy resins, gypsum, both conventional and polymer, various types of concrete, the mixture for the production of ceramics, and other similar materials.
ZA 40 THIXO FAST in primary form, is RTV silicone rubber, consisting of two components (base and catalyst), which is cured at room temperature.

2. Latex Rubber
Latex is natural rubber extracted from rubber trees found
mainly in Southeast Asia. To make this rubber usable as a
mold material, the raw rubber is usually processed with ammonia
and water. Latex is almost always brushed onto an original
model .
Advantages -- Latex is a one-component system (no
weighing necessary) that is ready to use right out of the
container. Latex is relatively inexpensive. Latex is an
elastic mold rubber and molds are generally thin-walled, strong
and exhibit good abrasion resistance. Because of its high elasticity,
a feature unique to latex is its ability to be removed from a
model like a glove. A latex mold will retain its shape after being
repeatedly rolled up and away (and turned inside out) from an
original model or casting – like a glove. Because of this feature
and its resistance to abrasion, latex is commonly used for making
“glove molds” in the reproduction of ornamental concrete (lawn
ornaments and statuary). Latex molds are also good for casting
wax and gypsum.
Disadvantages -- Low-cost latex products generally
shrink – on the order of 10 to 20% depending on product.
Making molds with latex rubber is slow and time consuming.
Brush-on molds made with latex require as many as 20
brush coats, with 4 hours of drying time between each coat.
Time factor for making a brush-on latex mold is ten days or
more. Many latex products have an ammonia odor (however,
there are new latex products on the market with lower shrinkage
and no odor). Latex molds are generally not suitable for casting
resins.
