Marine Antifouling Agent The First Global Solution for Copper-free Antifouling Paints

Marine biofouling is caused by settlement and growth of micro- and macro-organisms on ships and other marine

structures. These organisms can include marine plants and invertebrate animals like barnacles, hydroids, bivalve

mollusks and tube worms. Marine biofouling may impair the operational efficiency of a ship, in severe cases causing

up to a 40% increase in fuel consumption.

To date, the most effective and economical method to prevent ship biofouling is the application of an antifouling

paint that releases a biocidal compound. Since the ban on tributyltin as an antifouling biocide by the International

Maritime Organization (IMO), there has been a substantial shift to copper as the active ingredient of choice for

antifouling coatings. Most recently there have been regional efforts to restrict the use of copper for antifouling due

to environmental concerns.

The steady increase in copper price has spurred the search for cost-effective alternatives.

What is ECONEA® ?

ECONEA® (tralopyril) is an arylpyrrole compound developed by Janssen

PMP. ECONEA® is metal-free and represents the latest generation of

active ingredients for antifouling paints for ships and other marine

structures.

ECONEA® is about ten times more active than copper against marine

hard fouling organisms. Because it has a low water solubility and resists

leaching, ECONEA® containing paints can provide long lasting protection.

Depending on the paint formulation, ECONEA® can be as effective as

cuprous oxide at about one tenth the use concentration in the paint by

weight.

Once ECONEA® is released from the paint into the marine environment,

it breaks down rapidly. Registration has been granted or is in progress

in most of the key regions of the world.

unmatched technical service and global

regulatory expertise and support.

How to Formulate with ECONEA®

Effective use levels of ECONEA® in copper-free antifouling paints

are typically between 4 and 6 per cent by weight (on total formula,

wet paint). Alternatively, ECONEA® can be used in conjunction

with a copper-based biocide, either to reduce the copper level

without sacrificing performance or to increase the performance

and/or service life of copper-based products.

It is recommended to use ECONEA® in conjunction with a soft

fouling agent to ensure complete protection against both hard

and soft fouling. ECONEA® is fit for use in different types of

antifouling paint including traditional rosin-based Controlled

Depletion Polymer (CDP) paint types, as well as Self-Polishing

Copolymer (SPC) systems.

ECONEA® provides outstanding protection against fouling challenges from a wide spectrum of hard-shelled and soft-

bodied animal fouling organisms.

In addition to this intrinsic biological activity, ECONEA® has the necessary physical and chemical properties for it to

be effective in marine coatings. Because of its chemical and physical stability in coatings, the low water solubility

and leachability, ECONEA® containing antifouling paints can often be specified for multi-year dry-docking intervals

comparable to those achieved with copper-based products.

Antifouling Efficacy of ECONEA®

US Navy Qualification Testing

The Naval Sea Systems Command (NAVSEA) of the US

Navy has qualified SEAVOYAGE™ Copper-Free from The

Sherwin-Williams Company to performance specification

MIL-PRF-24647D, Application 1 (= service life of minimum

3 years).

International Paint has developed INTERSPEED® 5640 to

meet the same MIL spec. Both products are copper-free

and based on ECONEA® as the sole hard fouling biocide.

Environmental Profile of ECONEA®

ECONEA® is highly effective at controlling a wide range of fouling organisms while having an acceptable environmental

risk at recommended use concentrations.

After ECONEA® has exerted its antifouling effect and has been released from the antifouling paint, it is rapidly transformed

into degradation compounds that pose minimal risk to aquatic life at predicted environmental concentrations.

Furthermore, it has been demonstrated that ECONEA® has an extremely low bioconcentration potential in fish.

For its environmental attributes, ECONEA® was nominated for the 2010 European Business Awards for the Environment

organized by the Directorate-General for the Environment of the European Commission.

Fit for use on AluminiumECONEA® is particularly applicable for aluminium vessels where

the use of copper-containing products is often disregarded due to

concerns of galvanic corrosion.

Weight SavingsEliminating copper provides a substantial reduction in weight

and offers shipowners potential advantages of fuel savings and

increased tonnage.

Light and Bright ColoursUsing conventional copper-based biocides, it is difficult to

formulate light or bright coloured paints and still achieve optimal

antifouling performance. ECONEA® based antifouling paints can

be made available in clean, crisp, bright colours which meet the

highest antifouling performance standards.

Lower VOCECONEA® is suitable for the formulation of antifouling paints with

reduced levels of Volatile Organic Compounds.

ECONEA® offers the paint formulation chemist the possibility to achieve certain desired coating properties that would

otherwise be very difficult or impossible to achieve using the traditional copper-based antifouling biocides.

Improved Colour RetentionCopper-based antifouling paints generally exhibit a low consistency in colour throughout their in-service lifetime.

The use of ECONEA® allows the formulation of paints with unsurpassed colour retention.

Let’s Talk Honestly About

Cost

In former days it was more expensive

to formulate an antifouling paint with

ECONEA® than it was with conventional

copper-based biocides.

However, due to a continued effort

to optimize the production cost of

ECONEA® combined with increasing

copper prices over the last years,

ECONEA® has now become a

cost-effective alternative to copper

in antifouling applications.

Enabling Technology

Regulatory Status of ECONEA®

ECONEA® is approved as an antifouling preservative by the United States Environmental Protection Agency since 2007

(EPA Reg. No. 43813-27 and 43813-52). In addition, ECONEA® is supported as a new active substance under the

European Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) for Product-type 21: Antifouling Products.

Janssen PMP’s strategic goal is to have regulatory coverage for ECONEA® in all significant markets for antifouling

products worldwide. To meet the requirements of the various regulatory schemes in different parts of the world,

ECONEA® is supported by a comprehensive toxicological and environmental data package.

Owing to significant investments in the regulatory data package for ECONEA®, Janssen PMP is in a position to support

its customers’ registration efforts by providing Letters of Access to the relevant data and registration of the active

substance.

Use biocides safely. Always read the label and product information before use.ECONEA® may not be registered for certain uses in certain countries. For more information on the regulatory status in your country of interest, we invite you to contact us.As a Product Stewardship initiative, Janssen PMP has issued a booklet entitled Guidelines for the safe use of ECONEA® Technical.
