CLEANING AND PRETREATMENT

FOR PAINT

Chemetall Oahite, Berkeley Heights, N.J.

CrysCoat 600NR, a specially for- mulated blend of phosphates, ac- tivators, solvents, and surfac- tants, offers metal finishers a one- step manual method for cleaning and preparing large parts for painting in high-pressure or steam applications. The liquid de- tergent iron phosphate requires no rinsing and provides increased paint adhesion suitable for mod- ern finishes. CrysCoat 600NR is designed to remove soils typically encountered in the manufacture of large parts, counteract the ef-

fects of hard water, and reduce streaky coatings. Circle 403 on the reader service card

COAGULANTS

Be&Dearborn, Trevosa, Pa.

KlarAid coagulants are self-pre- cipitating with excellent heavy metal complexing abilities and an affinity for oil and grease. They perform effectively over a wide range of influent conditions and are safer and easier to use be- cause of their all-organic struc- ture derived from natural materi- als. KlarAid tannin and starch coagulants have minimal environ- mental impact, producing organic sludge that can be incinerated or landfilled. Circle 404 on the reader service card
