Brunel EnviroMarine System Benefits

The use of EnviroMarine system brings significant cost savings and benefits to the environment. To identify these benefits it is necessary to compare the principal alternatives to an EnviroMarine coating system.

Typical traditional solvent based paint

These systems involve many layers of coating in order to function. In addition to various additional ‘Tie Coats’ to atone for the incompatibility with their systems, these layers comprise:1 Primers to create mechanical bond to substrate.

3 Self-polishing coats that shed layers of paint into the marine environment.

 Pores formed from evaporation of solvents provide footholds for marine micro-organisms, which support barnacles and other marine growth.

This traditional system is solvent based and contains chemicals which contaminate the atmosphere. The process of evaporation also results in the presence of fine pores which provide footholds for marine micro-organisms which in turn support barnacles and other marine growth.

The damage this system causes to the environment is immense. The cost of regularly re-coating a vessel is equally immense.

Silicone Coatings

Silicone is a contaminant to other hulls and needs to be applied in total isolation – an expensive process. However this does not avoid contamination to the atmosphere.

Silicone coatings are also soft, non-durable and prone to erosion, particularly on areas not constantly underwater. They also leach contaminants into the marine environment.

Silicone based coatings have no track record of longevity, are not yet proven to be a cost effective way to protect the hull of a vessel and are likely to fall victim to future legislation.

Other Hard Coatings

EnviroMarine is the only hard coating made up of 100% solids. Other hard coatings can comprise Vinyl Ester, with the inherent problems that come with this product; or can contain chemicals such as Hydrogen Peroxide – a highly flammable and noxious material which can cause severe skin burn even, as with solvents, respiratory disease and cancer.

In order to function properly most hard coatings require an element of solvent, either integral or as an addition. Solvent, upon evaporation, leaves minute pores that harbour marine micro-organisms which nurture marine growth.

Hard coatings can require variable mixtures which are dependent upon ambient temperature and application is often by means of non-conventional equipment.

Some systems even require an additional and expensive conditioning process before the vessel can return to service!

Brunel’s EnviroMarine has many substantial benefits over these systems – both economic and environmental

Brunel EnviroMarine systemBrunel’s EnviroMarine System

• A chemical and mechanical bond to substrate and the chemical bonding of each layer, create a single impermeable protective coat.

• A totally inert coating with no chemicals released to the environment, creating a surface that improves ship performance.

• An impervious surface that will not support marine growth. Performance is maintained without the need to shed sacrificial layers.

EnviroMarine is the only coating guaranteed to be 100% solid, there is not even the smallest evaporation process or the slightest presence of the pores that will support future marine growth.

EnviroMarine contains no metals, biocides, or solvents. It will not contaminate the atmosphere on application, or release pollutants into the marine environment.

EnviroMarine is completely inert, safe to handle and presents no health hazard. It will not adversely contaminate other hulls, application personnel, or dockside structures.

Brunel EnviroMarine systemEnviroMarine can be applied quickly using a conventional airless pump. It needs no specialised equipment or training.

EnviroMarine can be applied in high humidity or light rain and does not need variable mixtures. The coating process will not be delayed by ordinary weather conditions.

EnviroMarine only requires only 2 coats of 150 microns. It minimizes application costs, dry docking time and additional vessel weight.

EnviroMarine requires NO additional conditioning process. A vessel can normally return to sea within hours of the last coat being applied.

EnviroMarine provides a chemical and mechanical bond to the substrate. Each coating combines to create ONE single impermeable protective coat which will not shed.

EnviroMarine cures quickly and provides a surface three times harder than concrete with a friction coefficient less than that of glass. It will aid a vessel’s efficiency and reduce running costs.

EnviroMarine is more flexible than the steel substrate and will not lose its film thickness. It is one homogenous coat that is designed not to wear away – performance does not degrade.
