Product Description

Ecoflex™ 5

Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage.  Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.

Skin Tite™

Skin Tite™ is a skin safe silicone used to create fast wounds, scars and to adhere silicone appliances directly to the skin. It can be sculpted “on the fly”, offers maximum control and stays precisely where you put it. Skin Tite™ will adhere to the skin and perfectly conforms to all contours. Cured rubber is strong and will flex with body movement. Wounds and appliances will not come off until you remove them. Material is skin safe and certified by an independent laboratory.

An infinite variety of color effects are achieved using Silc Pig™ silicone pigments. Blended Silc Pig™ color pigments added to Skin Tite™ will create hyper-realistic cuts, scars, slash wounds, bruises, necrotic (dead skin) effects, bullet holes and more. Thi-vex™ thickener will thicken Skin Tite™ for even greater vertical hang control and is ideal for creating skin pockets, hanging skin, deep cuts & wounds, holes and more.

Bio-Adhesive: Skin Tite™ can also be used to adhere skin effects silicone appliances or silicone masks to the skin even when affixed to hard to hold areas such as elbows, fingers and joints. It is ideal for repetitive motion applications. Skin Tite™ will release from closely cropped hair-covered skin surfaces (short arm hair, beards, moustaches and eyebrows).
