Abstract

Abstract A non-slip composition for application to a ground surface where lighting conditions may be poor including a polymer epoxy having two parts of diglycidyl ether resin and one part aliphatic amine adduct modified with 30% AEP as a stabilizer. A phosphorescent pigment including zinc, sulfide, and copper may be mixed with the epoxy to provide luminescent characteristics thereto. During application, a clear aluminum oxide aggregate is spread across a layer of the applied epoxy prior to curing, thereby enhancing the light emitting properties of the phosphorescent pigment as well as providing non-slip characteristics to the exposed surface of the applied layer of epoxy.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 79 words
A non-slip surface to be applied to an exposed surface comprising: a base structured and configured to be attached to said exposed surface in overlaying, covering relation thereto, and including an exposed planar surface portion, said base being coated on said exposed planar surface portion with a highly visible, anti-skid coating material which comprises polymeric epoxy compound mixed with a phosphorescent pigment which includes copper activated zinc sulfide, and further including an aggregate material spread therethrough prior to curing.
Claim 2
Dependent Claim 79 words
A non-slip surface to be applied to an exposed surface comprising: a base structured and configured to be attached to said exposed surface in overlaying, covering relation thereto, and including an exposed planar surface portion, said base being coated on said exposed planar surface portion with a highly visible, anti-skid coating material which comprises polymeric epoxy compound mixed with a phosphorescent pigment which includes copper activated zinc sulfide, and further including an aggregate material spread therethrough prior to curing.
Claim 3
Dependent Claim 38 words
A non-slip surface as set forth in claim 1 wherein said polymeric epoxy compound includes two parts per gallon of diglycidyl ether resin and one part per gallon of aliphatic amine adduct modified with 30% amyl ethyl piperidine.
Claim 4
Dependent Claim 15 words
A non-slip surface as set forth in claim 1 wherein said aggregate includes aluminum oxide.
