ERVIN INDUSTRIES

Circle 73 on Reader Service Card

The first cast steel shot and grit abrasives were produced by John

F. Ervin, who was awarded a U.S. patent in 1939 for his unique discov- ery of using alloyed steel to make a technically advanced abrasive prod- uct for blast cleaning and surface preparation.

Ervin Industries, Ann Arbor,

Mich., remains a family-owned busi- ness. A new product development center located in Tecumseh, Mich., is now being completed. This new research facility will support the continuous improvements that pro- vide customers of Amasteel with excellent product performance for surface preparation. Ervin Amasteel comes in three forms: shot, grit and a blend of the two.

The fundamental requirement is removal from the steel surface of a contaminants that would be condu- cive to premature paint failure.

Three principal degrees of blast- ing cleaning cleanliness are speci- fied and described by both the Steel

Structure Painting Council (SSPC) and the National Association of Cor- rosion Engineers (NACE).

ESGARD

Esgard, Inc., Lafayette, La., of- fers a wide range of coatings de- signed to offer optimum protection of marine and power transmission equipment. All Esgard coatings are formulated for environmental and worker safety while preserving op- erators dollars.

New to the market are the "P" products. These five coatings are all qualified under MIL-C-16173D, are easily removable and are VOC com- pliant. Their intended uses include preservation of power transmissions, gears, reducers and associated lube oil components, steam turbines and other machined metal equipment.

Each "P" product was designed to exceed specifications and the most stringent of clean air requirements.

The mainstay of Esgard's prod- uct lines are Bio Kote and Bio Float.

These coatings offer effective, safe, nonhazardous and economical pro- tection for ballast tanks, cofferdams and void areas on marine vessels.

Both are single package products which are applied over minimal pre- pared surfaces. Although they are 100 percent solids, they cure to a firm film which will not wash out and provides a safe surface for in- spection. Independent testing has shown no pollutants attributable to the coating.

Esgard sales, service and prod- ucts are available worldwide.

EUREKA CHEMICAL

COMPANY

Circle 75 on Reader Service Card

Eureka Chemical Company,

South San Francisco, Calif., manu- factures non-solvent base coatings and lubricants under the trade name, Fluid Film. The increase in the extended life cycle of in-service ships has resulted in a substantial increase in the sales of the liquid and semi-liquid non-solvent coat- ings for salt water ballast tank pro- tection.

Surface preparation is minimal.

The coatings are applied over rust scale at three to 15 mils thickness at a cost of three to seven cents per square foot. The liquid type is des- ignated Liquid A and may be ap- plied by flotation or spray. Protec- tion afforded depends on the condi- tions at time of application and will range from two to four years. Both coatings may be used as a descaler to clean surfaces, thus reducing maintenance costs substantially.

Both Liquid A and semi-liquid AR are transparent, and the fluid char- acteristic assures penetration to the base metal.

Fluid Film products will not evaporate and dry out like solvent base products. As an indication of the effectiveness and high quality performance, the company notes major producers with competitive coatings and lubricants, which specify Fluid Film tank coatings and wire rope lubricants instead of their own company's products.

MAGNAKOTE : The best way to avoid a tough scrape with your ship's worst enemy.

The easiest, most effective, and economical way to protect your ship's ballast tanks and void spaces from rust and corrosion is with MAGNAKOTE® rust preventative.

MAGNAKOTE's unique patent- ed formula penetrates the existing rust in your ballast tanks and pro- tects the base metal from forming new corrosion.

Easy to apply.

MAGNAKOTE rust preventative is easily applied, while in port or in transit, by spraying or float-coating.

The tank surface can be new or rusted, wet or dry. In approximately 36-48 hours, MAGNAKOTE cures to a pliable, transparent, protective film that will not crack or peel and protects for years.

No need for extensive surface preparation.

Apply MAGNAKOTE to a rusted surface and it penetrates right through the oxidized deposits to the base metal. As MAGNAKOTE rust preventative attaches itself to the metal, it breaks the bond between the oxide and the steel surface. With normal ship move- ments, the rust layer is dislodged and falls to the bottom of the tank.

No scraping, grit, or high-pressure water blasting procedures are necessary.

Protection that lasts.

Unlike coatings that simply cover the surfaces of ballast tanks and void spaces, MAGNAKOTE rust preventative actually bonds to the steel and forms layers of micro- scopic platelet crystals. The effect is like "fish scales," or layers of protection. Only a thin film of approximately 3 mils is necessary for long-lasting protection.

The MAGNAKOTE "LIFE

PRESERVER PROGRAM."

The fight against rust and corrosion is an ongoing battle.

That's why Drew offers the

MAGNAKOTE "LIFE PRE-

SERVER PROGRAM." With this program you get Drew's warranty, plus worldwide inspection of your ship's ballast tanks and void spaces by Drew Service

Engineers for as long as you are a MAGNAKOTE user.

MAGNAKOTE rust preventative:

Your ship's best protection against its worst enemy.
