This report covers bouse tests, field experience and studies of free chalking outside white bouse paint
Bade with soya PE oil. Soya PE 11 offer improvement.' in tints
and !Twc*Purpse tfhite as covered In Memorandum-Report-No &*66g This is .a separate, report because tbs material.covered is.not directly applicable to the .tints and Two~Purp8 House'Paint. However,- the experience with soya PE in free chaining' bouse paint
is extensive and -doe supplement ur knowledge of soya PE vehicles Report No,. K66:9- is issued simultaneously with this report.

MOISTORE BLISTERING;
Exposure Series 20821, 20817 and 9001 study moisture blistering only* The tests were run during the 2948-49, end 1950-51 seasons. Blistering tests were run on Series 10S2I during the 1949-50 and 1950-51 seasons* Thus, in four comparisons covering three seasons the soya PE paint was tested against
standard linseed oil paints* In all three studies the soya Pi paint was equal to the linseed oil control,
EROSION: .
;'v'
Conclusions on erosion should not be made yet because #108l6 is the only series listed below in which film thickness is controlled* Although first signs of bare wood are showing,
we should wait ffer sis months or a year when erosion is advanced before drawing definite conclusione* However, in the other studies soya PB consistently erodes to bare wood earlier, and, to be able to make allowances in any future free chalking soya PE formula^ w are exposing a small study of TiPure R-610/ TiPure T ladders in series 13600 to determine what level of TiPure R-610 Is needed to obtain chalking equal to 301-9X8
