antifouling

Medetomidine can be used as an antifouling substance in marine paint.

This red-coloured solid is a component of some antifouling paints.

This results in a more effective bottom paint that requires lower biocide levels to deliver full antifouling protection.

The steel plates, black in the earlier darkness, now became a dull red as the antifouling paint became more evident.

Not all sloughing serves an antifouling function.

Econea should always be combined with a secondary biocide to prevent soft growth and enhance its antifouling capabilities.

It is used as an environmentally friendly underwater antifouling coating for motor boats and sailing yachts.

This may be the first example of proactive antifouling technology (designed to prevent the attachment of fouling organisms, rather than to remove them).

Ablative paints are often utilized for this purpose to prevent the dilution or deactivation of the antifouling agent.

Engineering the antifouling agents and the ablation rate can produce long-lived protection from the deleterious effects of biofouling.

In addition to its antifouling benefits, copper netting has strong structural and corrosion-resistant properties in marine environments.

Alternatives to TBT include biomimetic antifouling coatings and ePaint.

Water Based (Hydrocoat Technology)- This formula uses water to replace the harsh solvents found in conventional antifouling paints.

A few natural compounds with simpler synthetic routes, such as nicotinamide or 2,5,6-tribromo-1-methylgramine (from Zoobotryon pellucidum), have been recently been incorporated into patented antifouling paints.

Interest in potential application of this compound as an antifouling agent for boats and other marine installations has led to attempts to produce it synthetically by convenient routes.

White Copper -(Cuprous Thiocyanate)- requires 50% less copper content than the heavy, dark copper used in conventional antifouling paints.

In particular, 2,5,6-tribromo-1-methylgramine shows 3-6 times the antifouling activity of TBTO against barnacle attachment while remaining 10 times less lethal to the barnacles.

Lethal effects of Mexel 432, an antifouling agent, on embryolarval development of common carp(Cyprinus carpio L.).

In 1917, Hempel collaborated with Technical University of Denmark on the development of the world's first antifouling coating for ships' hulls.

Some corallines slough off a surface layer of epithallial cells, which in a few cases may be an antifouling mechanism which serves the same function as enhancing herbivore recruitment.

An example of biomimetic antifouling research was conducted at the University of Florida into how marine animals like dolphins and sharks are able to effectively deter biofouling on their skin.

The free base form of medetomidine is distributed by the Swedish company I-Tech AB under the product name Selektope for use as an antifouling substance in marine paints.

During World War II they would revert to the marine industry, developing McInnes Green, an antifouling paint that was used in large quantities on US Government contracts.

Tributyltin (TBT) compounds found in some antifouling paint on ship hulls leaches into seawater and is toxic to marine organisms and humans; efforts are underway to restrict its use.

In his Fulbright studies, Mr. Sullivan said, he hopes to find a natural antifouling agent, perhaps a component of red algae, to replace toxic paints that are used to protect vessels from barnacles.
