Smooth-On Slacker Silicone Deadener 1 Pint — Softens Cured Silicone, Reduces Tack

Smooth-On Slacker is a professional-grade silicone deadener (tactile mutator) supplied as a 1 pint unit to reduce tack and soften cured silicones for moldmaking and flexible parts.

Slacker is formulated to modify the tactile properties of silicone elastomers used in molding, casting, and prop or special effects fabrication. Sold by Smooth-On in a convenient one-pint package for shop or studio use, this additive is intended for professional applications where changing surface feel, softness, or tackiness of cured silicone is required. It mixes into compatible silicone systems to alter their finished hand without replacing the base rubber.

How does Slacker change the feel of cured silicone?

When blended into a compatible silicone formulation, Slacker adjusts the elastomer’s surface and bulk properties to create a softer, less tacky finish. The result is a finished part that feels less sticky to the touch and can present a smoother, more realistic skin-like feel in prosthetics, props, or tactile samples.

• Softens cured silicone for a more pliable hand
• Reduces surface tackiness and cling
• Integrates into existing silicone mixes—no need for different base rubbers
• Packaged as a single 1 pint unit for lab or studio dosing

What are common uses for this tactile mutator in a workshop?

Slacker is used wherever silicone’s tactile characteristics need adjustment after formulation—moldmaking, prosthetics, animatronics, and product prototypes are typical applications. Professionals add it to silicone mixes to tune softness and surface feel while keeping desired mechanical properties such as flexibility and tear resistance as close as possible to the original.

• Prop and special effects silicone for realistic textures
• Mold linings where less surface tack is needed
• Soft-feel prototypes and consumer-touch surfaces
• Adjusting small-batch runs without reformulating base silicone

How is Slacker supplied and handled in the studio?

Smooth-On Slacker is provided as a one-pint unit sized for small to medium adjustments and batch work. As a professional product, it should be used according to Smooth-On’s technical data sheet and standard safety practices for working with silicone additives and resins—measure carefully, mix thoroughly, and observe recommended cure and pot-life guidelines for the base silicone you are modifying.

• One-pint packaging for controlled, workshop-friendly dosing
• Recommended for professional users familiar with silicone handling
• Measure and mix into the base silicone per product guidance
• Follow safety and storage recommendations on the product documentation

Will adding Slacker affect strength or cure time?

Adding a tactile mutator like Slacker will change tactile and some mechanical properties of the cured elastomer; the extent depends on the percentage added and the base silicone system. To preserve performance, add in controlled amounts and perform test pours to verify tear strength, shore hardness, and cure behavior before full-scale production.

• Performance changes vary by load percentage and silicone chemistry
• Small test batches recommended to validate results
• May require minor adjustments to cure schedule depending on the base system
• Designed for professional users who will verify mechanical outcomes

Who is this product for? Smooth-On Slacker 1 Pint Unit is aimed at professional moldmakers, special effects artists, prop fabricators, and R&D teams who need to fine-tune the hand and surface behaviour of cured silicones. If you routinely produce silicone parts and need to reduce tack or achieve a softer, more lifelike feel without switching base materials, this pint-sized tactile mutator provides a studio-scaled option for controlled adjustments and testing.
