Ecoflex 00-10 Super-Soft Addition Cure Silicone Rubber Pint - Very

In this review the Ecoflex 00-10 pint is recommended for artists, prop makers, and prosthetic crafters who need an extremely soft, highly elastic silicone that rebounds well after stretching. The single biggest reason to buy is its unusually low shore and superior stretch: mixed 1A:1B and cured at room temperature, this addition cure silicone produces a very soft, strong rubber ideal for lifelike appliances and cushions. The review notes practical tradeoffs too, including a tacky cured surface and a limited working time for larger pours.

Key Features

• Very soft cured rubber: The finished material stretches many times its original size without tearing, providing lifelike flexibility for prosthetics and soft effects.
• 1A:1B mix ratio: Easy by weight or volume, the equal parts mix simplifies measuring and shortens prep time in small-shop workflows.
• Low viscosity: Thin initial viscosity makes mixing and de-airing straightforward, improving detail capture in molds and casts.
• Color and viscosity options: Compatible with silicone pigments and silicone thinner so users can tint and lower viscosity for pours or coatings.
• Brushable and thickening options: THI-VEX thickener can be added for brushable applications, broadening application methods beyond simple pouring.
• Tacky cured surface: Note that cured parts retain a tacky finish which may require surface treatment depending on the application.

Who It's For

The Ecoflex 00-10 pint suits special effects artists, prosthetic makers, and anyone creating soft cushions or animatronic skins where repeated motion and high elasticity are required. Its very soft feel and ability to take pigment makes it useful for lifelike appliances and flexible molds that need to return to shape cleanly.

It may be less ideal for projects that demand a hard, non-tacky finish or very long working times for large castings; users who need a firmer shore or a fully non-tacky cured surface should consider other silicone grades or additional finishing steps.

Pros & Cons

Pros

• Exceptional softness and stretch make it suitable for realistic prosthetics and soft-touch parts.
• Simple 1A:1B mix ratio reduces measurement errors and speeds small-batch work.
• Low viscosity aids in mixing, degassing, and capturing fine detail in molds.
• Can be pigmented or thinned for custom colors and pour behavior.

Cons

• Cured surface is tacky, which may need post-treatment depending on the finish required.
• Working time and cure window can be restrictive for very large pours; plan pours and molds accordingly.

Our Verdict

Ecoflex 00-10 pint is an excellent value for creators who need one of the softest, most elastic addition cure silicones available, especially for prosthetics, animatronics, and soft cushioning. Its easy 1:1 mix and low viscosity make it practical for small studios, while pigment and thinner compatibility add versatility; just be prepared to manage the tacky finish and plan around the working time for larger pours.

Frequently Asked Questions

Can Ecoflex 00-10 be colored?
Yes. It accepts silicone pigments for a range of color effects and can be tinted before curing.

Is it suitable for animatronics?
Yes. Its high elasticity and rebound make it a good choice where repetitive motion and durability are required.

Does the cured surface require treatment?
Possibly; Ecoflex 00-10 cures with a tacky surface and some applications may need a coating or finish to reduce tack.
