  • Anti-traction compositions
    Patent number: 7625848
    Abstract: An anti-traction material is disclosed which may be used as a coating on a variety of surfaces over which people and vehicles may find it difficult to traverse. The anti-traction material may include polymer particles capable of absorbing or being dissolved by a fluid and a fluid capable of absorbing or dissolving the polymer particles. The anti-traction material may include hydrophobic particles which may then control the rate and/or amount of fluid absorption of the polymer particles which may therefore improve storage capability and polymer particle flow behavior.
