Notes:
1. For anatase pigments, ail suppliers are included in one assignment, Ti-Pure - DuPont, Titanox - Titanium Pigments, Unitane - Calco.
2. For rutile pigments, equivalent grades are grouped together above.
3. When possible, show all equivalent assignments as alternates on formula cards.
6. Mean particle size is 0.3 microns for anatase pigments and 0.3 to O.ii for rutile,

Whether anatase or rutile pigment results is dependent on the nucleation of the original liquor which largely determines the -crystal- structure of the hydrous Ti02 and partly on the conditions of calcination following the previously-mentioned metallic oxide treatment. The rutile types have
the greater opacity.
In making reduced grades, a finely-divided anhydrous CaSOt is added prior
to hydrolysis. The hydrous TiC2 is precipitated by hydrolysis cm the ex
tender to -which it is tightly held* resulting in a true composite futile -
pigment.

6600 Pull chalking anatase. A general purpose pigment where full-chalking is desired or not harmful. Primary use is in exterior house `paints.
6611 66C25;
Full chalking rutile grades analogous to 6600, used almost exclusively for emulsion paints. Although a greater hiding power is attainable in house paints, use of 6600 results in earlier chalking and greater whiting.
6603 Semi-chalking anatase. Useful to obtain balanced chalking rate and fr.r architectural white enamels. Use of the rstile grotp below (662C-6C2I-S622) is preierred,
6620) SenrL-chaiking rutile grades analogous tc 6603. The most versatile 6621) TiOg us.ed, its use is recommended except where maximum chalking _or 6622) maximum chalk resistance is imperative.
6630 Non-chalking rutile grades. General use is in exterior tinted enamels, lacquers and paints, and in interior-exterior enamels.
6608
Color-retentive chalking anatase. Modified for minimum discolora tion and after-yellowing, especially with synthetic resins, it is of primary use in baking finishes. Although whiteness of .6608 is higher, use of the more efficient rutile group (66UO-66I4I.-66U2) is recommended.
66h0) Color-retentive chalking rutile grades analogous to 6608. Modified 66Ul) for minimum discoloration and after-yellowing, especially with syn66I42) thetie resins, these represent the maximum gloss, opacity, whiteness,
brightness, and cclor stability attainable with rutile TiC,,. They
are particularly adaptable to baking finishes. Exterior use is not general since chalking may not be sufficient to insure acceptable re moval. of dirt collection.

Remarks (Con't.) 6680 A high water-sensitive reduced pigment used to modify chalking
of 6600, and where dry-hiding is required. 6681 A finer-textured, lower oil absorption version of 6680. 6682 A low water-sensitive, low wet-dry-hiding reduced pigment useful
to obtain low angular sheens, or where high humidity results in high consistency. 6685 A non-chalking, fade-resistant reduced pigment for exterior enamels and paints.
