International Classification:

C10M 173/00
C10M 149/06

US Classification:

508471, 508507, 508551, 508583, 106 36, 10628725

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.

Appl. No.:

11/735882

Inventors:

Ronald J. Mathis - San Antonio TX, US

Assignee:

SOUTHWEST RESEARCH INSTITUTE - San Antonio TX

International Classification:

A63H 27/00
A63B 65/10

US Classification:

446 46, 446 48, 473589

Abstract:

The present disclosure relates to a device and method for dispensing a substance. The device may include a body portion in the shape of an airfoil and includes a region to contain the substance to be dispensed. The device may include one or a plurality of ports which may include a covering having a mechanical strength (e.g. tensile strength) that is less than the mechanical strength of the body portion. The device may be launched either by hand or by a launching mechanism.
