UNITOR SEACARE ECOSPERSE 52<br />

Marine<br />

<strong>Chemicals</strong><br />

Product description<br />

Seacare Ecosperse 52 is a concentrated oil spill dispersant<br />

highly efficient for use on a wide range of oils. It converts<br />

hydrocarbons into fine emulsions that can be bio -<br />

degraded much more quickly in sea water. It can be applied<br />

by boat or aerial spraying.<br />

When authorized, this product can be used as a concentrate<br />

or diluted for many types of oil cleaning operations<br />

at sea, on rocky shoreline and beaches.<br />

Seacare Ecosperse 52 is non toxic and biodegradable.<br />

Seacare Ecosperse 52 official approvals and listings:<br />

Affairs. Reference No. MAFF/FEPA 129/2001. Type II and<br />

Directions for use<br />

Dispersion<br />

Oil Spills at Sea – Application from boat<br />

Seacare Ecosperse 52 can be used neat or diluted with<br />

sea water. It can be applied by spray from booms on work<br />

boats, hand sprayers or hoses using an injector.<br />

Used neat (Type III for UK & Scotland), 1 litre of Seacare<br />

Ecosperse 52 will disperse between 20 and 30 m2 of oil<br />

depending on the thickness and age of oil being treated.<br />

Used diluted (Type III for UK & Scotland), Seacare<br />

Ecosperse 52 can be diluted with seawater at a ratio of 1<br />

to 10. Mix immediately before use. 1 litre of mixture will<br />

cover approximately 10 square metres of oil spill. The ratio<br />

can vary depending on the type and thickness of oil<br />

spill. At sea one part of mixture will disperse 2-3 parts of<br />

oil.<br />

To maximize the efficiency of dispersion it is important<br />

that a dispersant is used at an early stage of the operation,<br />

before oil weathering takes place.<br />

Oil Spills at Sea – Aerial Spraying<br />

In the UK, aircraft using the appropriate form of spraying<br />

equipment which has been tested and found satisfactory<br />

by AEA Technology Plc. may spray Seacare Ecosperse 52<br />

over the sea, the product being used neat. Seacare<br />

Ecosperse 52 has passed tests in accordance with the<br />

specification of the UK Ministry of Defence.<br />

Cleaning<br />

Oil on beach and rocky shore<br />

Remove and reclaim as much oil as possible. Then using<br />

suitable spraying equipment, spray Seacare Ecosperse 52<br />

over the oiled areas using one part of dispersant to 7-20<br />

parts of oil. Wash down the beach or rocks with water.<br />

The quantity of product used depends on the type and<br />

thickness of oil spilt, also on the amount of weathering of<br />

the oil. In some cases several applications may be necessary.<br />

Use in the UK (Department for Environment,<br />

Food & Rural Affairs) & Scotland<br />

Definition<br />

The following classification and definition of oil spill treatment<br />

products is valid for the UK and Scotland:<br />

Type II : Water-dilutable Concentrate - for use at sea after<br />

dilution 1:10 with sea water and sprayed from WSL spray<br />

sets using breaker boards or other suitable means of application<br />

and agitation.<br />

Type III: Concentrate - for use undiluted from aircraft, ships<br />

or on beaches, using appropriate spray gear.<br />

Notes for guidance<br />

It is the responsability of the user to comply with the restrictions<br />
