LIST C Proposals of Little General Interest But Some Few May Have Merit for Future Long-Range Projects C-l Make an M50 type of pigment but replace the chromium with some other ele ment. (l) C-2. Makm an M50 or M50 type containing a third or even a fourth element (in addition to the lead ami chromium). (2) C-3. Oncor "tint" pigments: single pigments to make a gray, a cream, a light blue, etc., like the Krebs tinted titaniums of the 1930's and early 40's. w C-4. Make an Oncor type pearlescent pigment but keep the silica content low. C-5* (6) Ii Use colored glasses -- perhaps as beads -- as pigments in paints, or coat particles of glass or pigments with reflective transparent films. (10) C-6. Use gels such as Bentone, silicate gels and lead gels of low refractive in dex in clear finishes to obtain finishes of greater durability. (12) Use a light-sensitive glass as a "pigment" in clear finishes, possibly to offer protection to the vehicle. (29) C-7 A chromate or chromium oxide core as a substrate for any of a variety of coatings (TiOg, AlgO^, silicates, etc.) to provide anticorrosive proper ties in various colors; phosphates should also work. (13) C-8. Use an Oncor basic zinc chromate for traffic paints because of its cheap ness and brilliance. (l4) ML 000041460 List C, Coat'd. -2- C-9- Resihated Oncer pigments - typified "by resinated Ti^-coated silica and resinated zinc-chromate coated silica - have demonstrated good exposure results. (15) C-10. Organic derivatives of chromic acid should have greater solubility of the chromate ion and therefore better metal protection as coECE.red to inorganic chromates; organic lead-chromate pigments may prove of interest, (lb) C-ll. Make a pigment having both organic and inorganic components, ex.g., a lead compound with maleic acid, styrene and chromate. (20) C-12. Combinations of pigment and polymer which can be in dry powder form and con stituted into a finished paint by simply stirring into tap water. (25) Encapsulate pigments with polymers to nuke :,stir-in" paints. (37) | C-13. Other Oncor-type pigments having coatings of available organic pigments such as duPont's Monastral Red. (26) C--lto. Investigate sensitivity of lead compounds to radiation for possible utility in color TV, etc. (36) Investigate halogenated phosphors for TV tubns. (kg) C-15- Put functional groups on ferrocene-type eompoinds. (55) C-l6. Investigate Bentone derivatives as pigments, ex.g., the old Bentone Blue. (69) C-17. Utilize increased pigment agglomeration to improve exterior durability. (70) C-l8. Materials made on the Oneor principle might have utility as fillers in ad hesives, epoxies, etc. (71) NL 000041461
