Ecoflex GEL is an extremely soft, platinum silicone rubber gel specifically designed for creating silicone makeup appliances, for cushioning, creating gaskets, encapsulation, and other applications requiring a very soft silicone material. 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 Silc Pig ; silicone 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.
