ADVANTAGES

 

Exceeds the minimum Highways Agency requirements for skid resistance and texture depth.

 

(SRV 65+ (using calcined bauxite)).

COMPONENTS

 

BINDER

The binder consists of a thermosetting modified epoxy/amine compound which holds the aggregate firmly in position, and has excellent adhesion to the substrate. It is applied above 5°C at a minimum application rate of 1.35kg/m_ (typically 1.8kg/m_ depending on the type and rugosity of the substrate) and complies with Table 1.

Properties (after 7 days curing @ 23°C)

Tensile Strength @ 23°C           10.5N/mm _min

Elongation at break at 23°C       30% minimum

 

 

AGGREGATE

The aggregates used are natural or pigmented calcined bauxite which has a typical Polished Stone Value (PSV) of 70 and Aggregate Abrasion Value (AAV) of 4., or high PSV (typically 60+) natural coloured or pigmented aggregates which provide a coloured skid resistant surface.

The average coverage rate is 7 – 8 kg/m_ and typical gradings comply with Table 2.  The aggregate should be clean and free from foreign matter.

WHAT IS IT?

 

Epoxy Resin is a highly durable, specialist hand or machine applied coloured

skid resistant surface treatment, consisting of a thermosetting modified

epoxy/amine binder which is usually pigmented and dressed with natural coloured

or pigmented aggregate, typically calcined bauxite or granite. 

 

It provides a well textured surface typically 5mm thick for the standard road grade

and 2-3mm thick for the pedestrian grade. 

 

The system can be readily applied to asphalt, macadam and concrete surfaces

providing the latter is suitably primed.
