How to Make Durable Non-Slip Surfaces Using Electron Beam Curing

A method for creating flexible, non-slip materials by bonding mineral grit to plastic sheets using a special radiation-cured glue that stays strong even when stretched.

What it covers

This patent describes a way to create a non-slip material by gluing abrasive mineral particles onto a flexible plastic backing. The key is using a specific type of polyurethane adhesive that is cured—or hardened—using an electron beam. Because the adhesive is radiation-cured, it forms a strong, flexible bond that allows the entire sheet to be stretched or thermoformed into complex shapes without the grit falling off or the layers separating. This is useful for things like safety flooring or grip pads that need to wrap around curved surfaces.

What it doesn't cover

• —Does not cover non-slip materials that use heat-cured or air-dried adhesives instead of radiation-cured binders.
• —Does not cover materials where the abrasive particles are embedded into the plastic rather than bonded to the surface.
• —Does not cover adhesives that lack the specific blend of polyester urethane acrylate resin and the defined monomers.
• —Does not cover applications where the material cannot maintain at least 125% elongation before tearing.

The clever bit

The innovation lies in the specific chemical formulation of the binder that allows the finished product to remain 'thermoformable'—meaning it can be heated and stretched into a new shape without the grit layer cracking or peeling away from the plastic base.

Why it matters

Before this technology, non-slip coatings often cracked or delaminated when applied to complex, curved surfaces. By using electron beam curing, manufacturers could create high-performance grip materials that were thin, flexible, and durable enough to be molded into shapes like vehicle interiors or industrial safety components.
