Supplied in a convenient one-pint unit, this product is intended for professional, industrial, and advanced hobbyist applications where controlling durometer, tack, and feel of silicone elastomers matters. Use it to tune silicone shore hardness, produce muted-surface finishes, and add an internal deadening effect to thin-walled castings.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Slacker change the feel and hardness of silicone parts?\u003c\/h3\u003e\n\u003cp\u003eSlacker dilutes and plasticizes cured silicone, lowering surface tack and reducing apparent shore hardness when blended correctly. It integrates into RTV and pouring silicones to create softer, more lifelike textures or to achieve a specific tactile response in finished parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMix ratios alter final softness — small additions subtly soften, higher percentages produce markedly lower durometer.\u003c\/li\u003e\n  \u003cli\u003eCompatible with many addition- and condensation-cure silicones when used per manufacturer guidance.\u003c\/li\u003e\n  \u003cli\u003eHelps eliminate sticky surfaces without introducing abrasives or fillers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat applications benefit most from this silicone deadener?\u003c\/h3\u003e\n\u003cp\u003eSlacker is used where touch, sound, or vibration control is important: special effects props, soft prosthetics, replica skins, vibration-damped components, and thin silicone castings that need a less rigid feel. It is popular in moldmaking and finishing processes to achieve a more natural give and quieter performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSpecial effects bodies and creature suits needing realistic softness.\u003c\/li\u003e\n  \u003cli\u003eThin-walled silicone parts that otherwise feel harsh or snap back too quickly.\u003c\/li\u003e\n  \u003cli\u003eAcoustic damping for silicone-mounted components or prop elements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do you use Slacker safely and effectively in a workflow?\u003c\/h3\u003e\n\u003cp\u003eWork with measured ratios and test small batches first to dial in the desired softness and cure characteristics.

Smooth-On Slacker 1 Pint is aimed at professional moldmakers, special effects artists, prop shops, advanced hobbyists, and engineers who require fine control over silicone tactile properties and acoustic behavior. If you need to reduce tack, soften silicone parts, or tune the feel of finished castings, this product gives a precise, testable way to adjust silicone performance in small-batch or studio environments. Not intended for consumer crafts without appropriate experience—follow all technical safety and compatibility guidance from Smooth-On for best results.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is Smooth-On Slacker compatible with all silicones?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Slacker works with many addition- and condensation-cure silicones, but compatibility varies.
