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 />

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 />
that can apply for each country regulation and<br />
depending if the product is used as a dispersant and/or as<br />
