Smooth-On Silicone Effects Kit – Ecoflex™ 00-20 + Slacker™ (1 Pint Each) – Skin-Safe, Flexible Silicone for FX, Prosthetics & Molding

Elevate your silicone casting projects with this high-performance Smooth-On duo – the Ecoflex 00-20 Super Soft Silicone Rubber and Slacker Silicone Deadener. Whether you're a special effects artist, medical prosthetics designer, or cosplay creator, this kit provides the versatility, realism, and skin-safe assurance you need. Ecoflex 00-20 offers unmatched softness, stretchability, and strength, making it ideal for highly flexible molds and lifelike prosthetics. With easy 1A:1B mixing, low viscosity, and room-temperature curing, it's beginner-friendly and professional-grade. Pair it with Slacker, a silicone deadener that modifies texture, softness, and rebound characteristics, to create silicone that looks, feels, and behaves like real human flesh – including wrinkling and bending with movement. Color with Silc Pig pigments, thin with Silicone Thinner, or thicken with THI-VEX to match your desired effect. This is the ultimate combination for creating soft-touch, skin-safe silicone with customizable realism.

• All-in-One Silicone Kit for Realistic FX & Prosthetics: This combo includes 1 pint each of Ecoflex 00-20, a platinum-cure silicone rubber, and Slacker, a silicone deadener. Together, they allow you to create ultra-realistic, flexible silicone pieces for film, medical, cosplay, or orthotic applications. Perfect for both professionals and hobbyists looking for skin-safe, high-performance results.
• Ecoflex 00-20 – Ultra-Soft, Durable & Highly Stretchable: Ecoflex 00-20 cures to a super-soft, incredibly stretchy rubber that can extend several times its length and snap back without tearing. It’s ideal for use in animatronics, soft robotics, cushioning components, and prosthetic appliances, with a certified skin-safe and body-safe formula that’s safe for prolonged wear.
• Slacker – Realistic Tissue Texture Without Residue: Slacker modifies cured silicone to simulate the soft, fleshy feel of human tissue—perfect for special effects artists, medical simulators, and anaplastologists. Unlike silicone oils, Slacker blends seamlessly without leaving greasy residue, providing a more stable, mess-free finish that holds up over time.
• Mix & Customize for Desired Consistency: Adjust the Slacker to Ecoflex ratio to achieve anything from tacky, self-adhering appliances to gel-filled prosthetic inserts. This flexible mixing system allows for extreme customization—ideal for replicating everything from soft skin layers to dense cushioning pads.
• Compatible with Smooth-On Additives for Advanced Effects: Tailor your material even further with Silc Pig pigments for lifelike color matching, Silicone Thinner to lower viscosity for easier pouring into molds, or THI-VEX to thicken silicone for brush-on applications and layering. Whether you're casting, brushing, or tinting, this kit adapts to your creative workflow.
