Title:
FRICTION CONTROL ARTICLE FOR WET AND DRY APPLICATIONS
Document Type and Number:
WIPO Patent Application WO2002013638
Kind Code:
A3
Abstract:
A friction control article (20) including a backing layer (21) having a first surface (24) with an array of at least 100 upstanding stems (26) per square inch and a second surface (25). At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.
