Today's new classes of Anti-Slips are generally epoxy and contains aluminum oxide. Epoxies are tough and chemically resistant while aluminum oxide is highly abrasive and resistant to wear. What makes these products unique is the way they are applied. Most Anti-Slip coatings are rolled using a napless roller. This is the solvent resistant phenolic core which you would expect to see inside your regular nap roller.
Application is performed by pouring ribbons of the coating and rolling it out in one direction.
When the roller pulls the material, it creates unique ridges with furrows and troughs. These high and low areas provide improved traction. In harsh environments or where water or oil is present the liquids flow in the valleys between the ridges. These coatings can raise the coefficient of friction from 0.5,which is OSHA's minimum for smooth floors to greater than 1.20. Some coatings are sprayed but the majority in the marketplace today are rolled.
