Because this paper marks 50 years since the first Mattiello Memorial Lecture, it begins with a remembrance of the man in whose honor we meet and an appreciation of his character and his contributions to the coatings industry. The body of the paper is concerned with the coating used on a hull of a ship to prevent the accumulation of barnacles and other fouling. The most effective antifouling paint now being used contains toxins and will be forbidden by international regulations within eight… Expand
FP-based formulations as protective coatings in oil/gas pipelines
Abstract Corrosion in the interior of pipelines is a major and costly problem encountered in the oil and gas industry. In this context, a fluoropolymer and a hybrid epoxy/fluoropolymer resin wereExpand

Non-eroding silicone-based coatings can effectively reduce fouling of ship hulls and are an alternative to biocidal and heavy metal-based antifoulings. The products, whose formulations and make upExpand
Development of polyorganosilazane–silicone marine coatings
Abstract The objective of the present work is the development and characterization of marine coatings based on polyorganosilazanes (PSZ). Two types of coatings containing silicone oils and biocidalExpand
Non-silicone biocide-free antifouling solutions
Abstract: The prevention of biofouling attachment and growth on vessel hulls and other immersed surfaces has, and continues to be, primarily achieved through the use of antifouling paints, whichExpand
A review on protective polymeric coatings for marine applications
The main objective of this review is to discuss the recent research on polymer-based surface coatings contributing to the protection against marine biofouling based on the knowledge available inExpand
Elastomeric fluorinated polyurethane coatings for nontoxic fouling control
A new coating which combines the best features of fluorinated and silicone coatings and is non-toxic is described which is shown to foul slowly, clean easily, be durable in the marine environment and organisms bonded to it only weakly. Expand
Hydrophobic coatings from emulsion polymers
One of the chief requirements of protective coatings is the ability to confer water resistance to painted substrates. To accomplish this task, the coating itself must be water resistant but shouldExpand
Effects of pigmentation on siloxane–polyurethane coatings and their performance as fouling-release marine coatings
Siloxane–polyurethane paints were formulated and characterized for coating properties and performance as fouling-release (FR) marine coatings. Paints were formulated at 20 and 30 pigment volumeExpand
The dominant presence of marine diatoms fouling the latest non-toxic, antifoul coatings has increased interest in characterising diatom adhesives and the mechanisms of their adhesion. In this studyExpand
Bioprospecting Novel Antifoulants and Anti‐Biofilm Agents from Microbes
The chapter suggests that marine host organisms that lack their own chemical defense mechanisms may be colonized by antifouling-producing bacteria, such as Pseudoalteromonas species. Expand


The concept of producing coating sufficiently anti-adhesive that marine foaling organisms attached to the surface can be removed by relatively small mechanical forces is being investigated. CentralExpand
Novel non-toxic coatings designed to resist marine fouling
Abstract Coatings designed for applications as non-toxic non-fouling coatings have been prepared. Conventional coatings used in this application suffer from lack of adhesion to the substrate and lackExpand
Properties which influence marine fouling resistance in polymers containing silicon and fluorine
Our research strives to understand and construct polymer surfaces with no inherent power to interact with other materials, especially with the biological polymers used by marine organisms to bindExpand
Compositional effects on the fouling resistance of fluorourethane coatings
ConclusionsA series of fluorinated polyurethane polymers have been prepared and characterized. Immersion experiments have been performed to determine the fouling-release effectiveness of theExpand
Mechanical factors favoring release from fouling release coatings
The types of bonding associated with polymeric materials used in fouling resistant coatings are reviewed, the removal process is described in terms of fracture mechanics, and the importance of surface energy, elastic modulus and coating thickness in the release of biofoulants is discussed. Expand
Barmacle Cement-Key to Second Generation Antifouling Coatings
First generation antifouling coatings show depletion in time of toxic content by the slow leaching out into sea water. Up to 3-yr effective fouling prevention on ships identifies such coatings.Expand
The Phenomena of Rupture and Flow in Solids
In the course of an investigation of the effect of surface scratches on the mechanical strength of solids, some general conclusions were reached which appear to have a direct bearing on the problemExpand
Pull-off behavior of epoxy bonded to silicone duplex coatings
Abstract Flat-head studs, 7.2 mm diameter, were epoxied to 0.1–0.9 mm thick silicone layers attached to a rigid substrate. Pull-off tests were performed at nominally 1.5 N/s to establish criticalExpand
Macrofouling of hydrocarbon polymers which contain variable proportions of crystallinity
The effect of crystallinity on the ability of a hydrocarbon to resist attachment to marine fouling organisms has been investigated. Polymers composed only of carbon and hydrogen were casted orExpand
Self-assembled water-borne fluoropolymer coatings for marine fouling resistance
SummariesFluoropolymer coatings were prepared by crosslinking a polymeric perfluoroalkyl surfactant with a poly[(2-isopropenyl-2-(oxazoline)]. Marine organisms adhered to these coatings withExpand
