Rhino Linings Raleigh – Lining Specifications

Technical Specifications - TuffGrip™ Polyurethane Product Description

TuffGrip polyurethane is a two-component, 100% solids (no VOCs), fast-curing, elastomeric polyurethane coating system. It provides high film build, excellent abrasion resistance, excellent weather resistance, along with good resistance to chemical and process environments. TuffGrip has high tensile strength, elongation and tear strength properties.

Definition of Terms:

"Shore A" Hardness
This test involves the penetration of a specific shaped point when forced into the elastomer surface. "Shore A" specifies the type of durometer. This test permits hardness measurements based on initial indentation and/or indentation after a specified time period. The reported value of 90 Shore A is for an initial reading.

Tensile Strength
The reported tensile strength is the force required to stretch the elastomer in one direction. The reported value is 1700 psi at break. In other words, 1,700 pounds could be suspended from a one inch square rod before failure.

Elongation
This is the distance the material can stretch before failure. 100% elongation implies that a sample can be stretched to twice its original length before breaking. 200% elongation means the sample can be stretched to three times its original length before failure occurs. The higher the elongation value, the more elastic the material.
