Ecoflex™ GEL has a Shore hardness of 000-35, this is below the Shore 00 hardness scale. Because Ecoflex™ GEL is so soft, it works very well as a silicone gel for filling encapsulated silicone makeup appliances and prosthetics. An infinite number of color effects can be achieved by adding silicone pigments as well as other effects pigments. As Ecoflex GEL is very tacky when cured, in some situations, it is recommended that Ecoflex™ GEL be encapsulated with another non-tacky platinum silicone such as Dragon Skin FX Pro, or another suitable membrane. Ecoflex™ GEL is mixed 1A:1B by weight or volume. Rubber cures at room temperature (73°F / 23°C) with negligible shrinkage. Available in trial (2 pint) sets and 2 gallon sets.
