АKLEN 06-U – modificated polymeric universal composition for 2-3- layer PE steel pipes coating system. The product is supplied in granules for application by coextrusion.

Chemical structure

Grafted copolymer based upon composition consisting of HDPE polyethylene and linear polyehtylene (LLDPE) with grafted function-associated anhydride and carboxylic groups.

Applications

АKLEN 06-U is recommended as an adhesive for 2 -3– layer extruded PE systems for water- gas-oil pipelines in accordance with EN 10288, DIN 30670, ISO 21809-4, CSA Z245.21, ISO 21809-1, NFA 49-710, Shell DEP. 31.30.40.31

Operating temperature -45°С …+90°С.

Recommended processing temperature.

Aklen 06-U is applied for standard extrusion equipment. Effective temperature range for composition Aklen 06-U is defined within 170°С – 210°С. Effective temperature range for steel pipes surface during PE coating operation is defined within 180°С – 220°С. In case if pipes surface temperature will exceed effective temperature to be 230°С inclusive, thus adhesion to the steel pipe will not exceed values indicated in present specification.

Packaging and Storage.

Packed in 25 kgs paper-polypropylene bags or 1000 kgs polypropylene big bags.

Store in dry and ventilated place, avoid direct UV rays and contact with water.

Shell life: 24 months.

Safety.

The adhesive is not classified to be a dangerous one.

The equipment should be grounded in case of any dust explosion caused by dust during operational procedure. Ventilation is necessary to avoid inhalation, because it irritates respiratory tract.
