Gilsonite paint, when fluxed with raw tung or oiticica oil, gives an unstable liquid, that is, one which will take on excessive body when aging, and one which is not gas-proof.
On the other hand, when we fluxe the gilsonite coat with tung or oiticicaoils and heat-treat with the additions of gums or resins in the ordinary fashion, the resulting paint becomes full of check marks and deteriorates rapidly, particularly upon exposure.
The use of the present type of oils, however, results in a paint which does not take on excessive body upon aging and at the same time does not check and deteriorate rapidly upon exposure.
A paint consisting essentially of 20 gallons of petroleum solvent and 10 gallons of linseed oil,10 gallons turpentine, pounds of Gilsonite pigment, 4 gallons varnish mixture consisting of 17.8% pentaerythritol rosin ester, 30.8% dehydrated castor oil, 1.4% of a mixture of lead
