it uses a standard test method al- ready approved by both the scien- tific and commercial communities.

The major attributes of the test pro- cedure are as follows: measurabil- ity, repeatability, simplicity, con- trolled conditions and cost effective- ness.

In summary, the proposed per- formance standard is relevant to the blast cleaning/painting indus- try and establishes criteria for cost benefit analysis.

Corroseal, Inc. produces two prod- ucts for marine use at its plant in

Seattle, Wash. The first product is

Corroseal™, a rust convertor and metal primer used in daily mainte- nance all types of marine vessels.

The second product is Crystal Lok™, a concrete hardener and waterproofer for ferro cement hulls, concrete dry docks, wharfs and other shore structures.

Corroseal™ converts rust to an inert substance called magnetite and at the same time polymer primes the metal for top coating.

This conversion process, when ap-

You want a shipyard that will work with you to get the job done. One that knows that your project is unique, and has what it takes to do it right. A shipyard with a reputation for quality, productivity, and customer service that's second to none. A shipyard like Todd. If it's important to you, it's important to

It does not dissolve the rust into the metal primer coating but rather con- verts it where the rust occurs to a non-rusting, inert substance.

Corroseal™ is an ideal product for ship, tug or barge maintenance of corroded surfaces. It is nonflam- mable, contains no toxic pigments, is VOC compliant at 60 grams-per- liter, has no offensive odors and its mild, converter formula has a pH between grapefruit juice and orange juice.

This makes the product user friendly and a reported favorite of vessel crews because it is easy to apply. It is especially effective on welds.

Crystal Lok™ is not a coating. It penetrates new or existing concrete and hardens the surface, locking out moisture it reduces effervescence and chloride intrusion of concrete and it will stop moisture penetra- tion of concrete up to 300-inch im- mersion depth. This helps prevent rusting of rebar or steel in concrete and thus prevents spalling or break- ing up of the concrete.

DEVOE

Founded in 1754, Devoe Coat- ings, Louisville, Ky., is one of the oldest companies in the U.S. and reportedly the oldest paint company in the world. Over the years, Devoe has been a major contributor to coat- ing technology. From Devoe's origi- nal invention and patent of the ep- oxy resin back in the 1940's, the company has maintained a leading position in epoxy technology.

Devoe offers a diverse range of products under trade names Devran,

Bar-Rust and Devchem. The prod- uct range includes coatings designed for underwater application, low tem- perature cure, surface tolerant and the industry standard in chemical tank linings.

Not only has Devoe been a leader in epoxy technology, but the firm also was one of the first companies in the world to offer organotin-free ablative antifoulings. Its ABC line of antifoulings has proven perfor- mance in waters around the world.

DU PONT COMPANY

Circle 72 on Reader Service Card

Du Pont Company, Wilmington,

Del., offers Starblast XL blasting abrasive for the marine industry.

At less than one percent free crys- talline silica, Starblast XL abrasive has been added to the Navy's Quali- fied Product List and is CARB ap- proved.

The abrasive is said to be excep- tionally efficient and economical due to low-dusting, faster cleaning rates, less clean-up time and virtually free of heavy metals.

Starblast XL abrasive leaves a surface profile of 1.8 to 2.2 mils, which is ideal for maximizing coat- ing adhesion performance.
