Premium Polymer 80:

• Our most popular polymer-modified rapid-setting surface dressing emulsion;
• The addition of polymer gives it improved tensile, cohesive and adhesive strengths, compared to a Cationic 70 %;
• Is more resistant to the higher summer temperatures.
• Ideal for surface dressing highly trafficked roads;
• Is particularly suitable for use with multi-layer surface dressings, such as racked-in or double surface dressing processes;
• Produces a highly stable interlocked aggregate mosaic, thereby reduces early life chip-loss and provides a durable long-life surface dressing; and
• Should only be applied during the months of May to September, as it required good drying conditions.

Composition 160-220 pen bitumen, water bitumen emulsifiers, adhesion agents, block co-polymer and fluxant.
Temperature Application temperature 80-85°C.

• Store in Insulated, heated tanks with thermostatic control.
• Storage temperature 40-70°C for long term storage protect from frost.
• Circulate tanks before loading.
• Before spraying heat to 80-85°C and circulate.
• Precautions non-flammable but will boil and develop steam pressure above 90°C

• Premium Polymer 80 should be sprayed using purpose built Emulsion Sprayers properly maintained and calibrated in accordance with BS1707 and EN12272-1.
• Application rates should be designed to suit the particular circumstances of the site.
• Best results in Surface Dressing will be achieved during the main Spraying Season April- September.
