ΟίΙ Well Drillers: higher yields wi thout costly t reatment when using MCP's improved Attapulqus Dril l ing Clay

Gyp, salt, oil emulsion, and completion muds — MCP's Attapulgus Drilling Clay is lower-cost than bentonite in just about any drilling mud. Why ? Substantially higher yields, and continued stability in the presence of field contaminants without requiring costly chemical treatment. Graph shows evidence of comparative perfor­mances in gyp solutions. Viscosity and water loss rate of the Attapulgus Drilling Clay suspen­sion is practically unchanged, from initial make­up in fresh water throughout continued build-up of gypsum concentration. However, the bentonite suspension solution shows a steady loss in vis­cosity and increase of water loss rate.

*Paillt Makers: get fine grind quickly, superior suspension with Surface Modif ied ASP® extender pigments Required fineness of grind in shortest time, long shelf life are assured for organic surface coating systems using MCP's Surface Modified ASP 103 . . . graphs present proof. Other benefits: stability, weatherability, color integrity — ASP's are water-washed to uniform particle size and shape, virtual chemical inertness. There's much more to the role of ASP's in surface coatings . . . this is a starred item . . . use the coupon.

Patton Pigment Settl ing Gauge measures settl ing charac­teristics of paints. A weighted probe passes down through paint in quart can, at half-minute intervals distance above bottom is read and load increased. Readings provide a t profi le of settled pigment.

Results of Patton Pigment Settl ing Gauge tests on three formulations.Φ Each formulat ion was ground 5 hours and set on the shelf for 35 days. Then the settl ing character­istics were measured. Interpretat ion of results: The higher the reading, the more settl ing and the harder the body of settled pigment. In the ASP 103 formulat ion, the weighted probe went completely through the paint to the bottom of ihe can with minimum weight, in minimum t ime.

Waxes give up last traces of odor, taste to Porocel® adsorbent

More top quality waxes are produced with MCP's Porocel than with any other adsorbent. Porocel is in this top position because of its superior effici­ency for finishing waxes . . . even highly-hydrogenated waxes benefit from a final clean-up by Porocel. Par­affin waxes, micro-waxes, and petro-latume give up color bodies and lose organic acidity to meet the tightening specifications imposed.

Printing Inks with ASP'S give printer the clarity and finish he seeks

With a choice of the new surface modified organ-ophilic grades or the unmodified hydrophilic pig­ments, more printing inks now benefit from the superior soft texture, ease of dispersion, suspension properties, and economy of MCP's ASP aluminum silicate pigment extenders. They're grit-free, frac­tionated to narrow particle-size ranges to give that performance. Look into the ASP's . . . use the coupon.
