MOLYKOTE 3179
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses

Main features
- Dilatant Rheological Behavior
- Non-Slumping Static-Flow Resistance
- Novelty/Educational Toy-Market Use
Product Description
MOLYKOTE® 3179 Dilatant Compound is a unique, filled silicone polymer primarily designed for the novelty toy and educational markets. Exhibiting a coral or pink color, it provides a specialized combination of dilatant rheological properties that allow it to be stretched, snapped, and bounced by children. While it moves easily under low mechanical force, it demonstrates excellent resistance to slump and flow when left at rest.
Key features
- High elasticity and bounce: Designed to offer high bounce (70% rebound) and stretchability for interactive handling.
- Non-slumping behavior: Resists static flow, allowing it to hold molded shapes like cubes, rectangles, and pyramids for weeks.
- Clean formulation: Formulated without intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS).
Applications / Suitable for
- Novelty toys designed for children to bounce, stretch, and snap
- Educational products demonstrating dilatant rheological properties
- Molding simple, semi-permanent shapes
