Drying tests, under controlled temperature and humidity conditions, of four sets of house paints-- three national brands; one made to Federal specifi cations--prove conclusively that paints containing white lead dry jaster! Especially in humid, dusty environments where prolonged wetness picks up damaging dust par ticles and debris, house paints with white lead in their formulations dry set-to-touch three to six hours sooner than lead-free paints. o X >, a !| P f N i1 r * _,' i ' i /:/! 11 1 l, ' % `s I , (, 4* ' K ,r > ' t ' r iI-K> i ' 1 *,' \ i' J .V 1 15- i ' : II ipfti i$nM mpmii mufeft Mm mm DA Manufacturer ; ` i vj ;; ij |> t. | l;. p.

The graph speaks for itself. The figures, taken from a standard, generally-accepted, stylus-type drying recorder--and confirmed by duplicate tests in separate laboratories--show clearly how white lead shortens the drying-time of house paints. "Lead" base and lead-free house paints, all mixed the same day, were applied to test panels to a thickness of three mils. Three paint manufactur ers, (A, B and C) each supplied a set of two brandname paints--one "lead" base and one lead-free-- for the tests. The fourth set (D) was made to Federal specifications: TT-P-102 ("lead" base), and TT-P-103 (lead-free). Two separate tests were made under different atmospheric conditions (warm and dry; cool and humid). These are valid reasons for the use of lead pigment in your paint formulations ... all valid sales argu ments. For detailed information on the most effec tive use of white lead in your paints--write for "White Lead in Mixed Pigment House Paints" and "White Lead Technical Bulletin #1."
