Traction surface and methods therefor

摘要

Devices and methods are contemplated in which a plurality of microfractures are generated on the surface of an article to so generate a non-abrasive surface having a COF of at least 0.6. Most preferably, the surface is the surface of a transparent polymer and is the surface is structured to allow high-resolution display of an image that is disposed on a surface opposite the surface with the microfractures. Consequently, numerous anti-slip products with such surfaces are contemplated.

主权项

1. An article comprising:
a transparent polycarbonate or acrylic polymeric layer having a non-abrasive micro-impacted microfractured first surface having a plurality of discontinuities, wherein the plurality of discontinuities extend into the layer and create a plurality of respective edges, and a second surface opposite the first surface; wherein the layer and the microfractured first surface have a structure effective to allow for optical resolution of an image coupled to the second surface of equal or less than 1 mm; and wherein the microfractured first surface imparts a coefficient of friction (COF) of at least 0.6, and wherein the COF is determined per ASTM F1677 or ASTM F1679.
