Natural asphalt using in industrial sector


Natural asphalt in Paint.

A paint consisting essentially of 20 gallons of petroleum solvent, 10 gallons of linseed oil, 10 gallons turpentine, pounds of natural asphalt pigment, 4 gallons varnish mixture consisting of 17.8% pentaerythritol rosin ester, 30.8% dehydrated castor oil, 1.4% of a mixture of lead, cobalt and manganese naphthenates, 1 gallon wetting agent consisting essentially of salts of petroleum sulfonic acids, 2 quarts of drier, and 1 pint of a hydrocarbon silicon penetrating oil, obtained by heating a mixture of finely ground silicon dioxide under pressure to a temperature of about 300 F. with a distillate product obtained by subjecting natural asphalt to fractional distillation, said distillate product being that fraction which distills at a temperature range of about 430 F. to 438 F.

Natural asphalt in ink

Natural asphalt is widely used as the primary carbon black wetting agent for black news inks and headset and toner ink. ATDM natural asphalt resin competes advantageously with hydrocarbon resins, phenolic resins.

Natural asphalt in asphalt composition

We discovered that a synthetic flux oil can contain and deliver asphaltites, such as gilsonite, more easily and readily to an asphalt to improve its properties. The synthetic flux oil includes the asphaltite and a carrier oil. Depending on the nature of the carrier oil, the synthetic flux oil may or may not need to be heated during mixing and incorporation into the asphalt.

Natural asphalt in construction

Natural asphalt cement compositions are disclosed which utilize petroleum asphalt, natural asphalt, a reactive oil and an elastomer. These compositions produce superior natural asphalt cement that can give low viscosity during application followed by high viscosity, toughness and tenacity after curing on the highway.

Natural asphalt in foundry

Natural asphalt, an additive for foundry sand preblends providing reduced smoke and other emissions, the additive comprising a mixture of one part iron oxide as one part of a highly volatile carbonaceous material, and four parts of metallurgical coke. The additive is used as one quarter of the foundry sand preblend, the other three quarters consisting essentially of clays.
